Safe operation standards

BEKAR brand gas heaters are highly efficient and reliable products that meet the requirements of Russian and European safety standards. However, the following safety regulations must be observed:

• Do not use the heater where there are vapors of gasoline, acetone, paint thinners, alcohol or other flammable substances, or explosives.
• When using the heater, observe all local laws and ordinances in addition to national laws.
• When delimiting the heated space on separate zones using barriers made of materials such as tarpaulins and canvas impregnated with flame retardants, ensure a minimum distance of three meters between these materials and the heater. All barriers must be securely fastened.
• Use the heater only in well-ventilated areas, see Ventilation Requirements.
• Use the heater only in places where there is no excessive dust.
• Use only the voltage and frequency specified on the heater rating plate located on the heater case.
• Use only a grounded power cord with a three-prong plug
• Provide the following minimum distances from heater to combustible materials:
  - from the side of the hot air outlet - 3.0 meters;
  - from above - 2.0 meters;
  - rear and sides - 1.0 meter.
• To prevent a fire, an operating or hot heater must be placed on a level, stable surface.
• Keep children and animals away from the heater.
• Do not leave a running heater plugged in.
• Be careful: a heater equipped with a room thermostat turns on and off automatically at random times.
• Do not use the heater in residential or sleeping areas.
• Do not block or cover the inlet and/or outlet of the heater.
• It is forbidden to move, lift or service a hot, running or plugged-in heater.
• Premises where heaters are installed must be equipped with fire extinguishing means.
• Do not attach any hoses to the inlet and/or outlet of the heater. This can reduce the airflow through the heater and increase the amount of carbon monoxide in the exhaust air.
• Do not violate the established sequence of turning off the heater.
• Do not cover an operating heater.
• Do not use the heater below floor (ground) level as propane is heavier than air and will seep to the lowest level if it leaks.
• Keep the heater away from drafts, spray water and rain.
• Check heater for damage after each use. Do not use a damaged heater.
• Use only propane gas, 13 R.
• Do not allow the gas cylinder to heat up to temperatures above 37°C.
• Use only the hose and gas pressure regulator supplied.
• Keep the heater at least two meters away from gas cylinders. Never point the heater at a gas cylinder.
• Do not modify the design of the heater. Do not use a technically modified heater.
• This heater must use the spare parts provided when it was dismantled. Incomplete spare parts can cause serious injury and accidents.

Carbon monoxide poisoning is deadly!
The first signs of carbon monoxide (carbon monoxide) poisoning are similar to flu symptoms - headache, dizziness or nausea. If you have these symptoms, then the heater may not be working properly.
Immediately: 1. Turn off the heater.
2. Ventilate the room.
3. Go outside for fresh air.
Contact the service center!

Staff

• Each piece of equipment must be assigned to a specific employee. It is unacceptable that random people are engaged in the maintenance of heaters.
• Personnel whose functions include maintenance of heaters must be qualified, familiar with the requirements of this Manual, Rules technical operation and labor safety requirements in gas industry.

Design Description

The product is a blast gas heater direct action, which fully utilizes the heat of the burnt gas by mixing hot combustion products with blast air.

Areas of use

• For heating workshops, utility rooms.
• During the construction and performance of installation and finishing works.
• As an additional heater for non-residential premises.
• Everywhere and always when creation heating network expensive and impractical, as well as for seasonal work.

Product composition

The main design elements of the heaters are shown in Figures 1, 2 and 3.

Fuel

FUEL SPECIFICATIONS

• As a source of thermal energy in gas air heaters, a mixture of liquefied hydrocarbon gases is used, consisting mainly of propane (C 3 H 8), butane (C 4 H 10) and pentane (C 5 H 12); The main component of this mixture is propane.
• To ensure safety when using liquefied gases The user of a gas air heater must take into account the following properties:
  - liquefied hydrocarbon gases in ambient conditions are in a gaseous state, and with a slight increase in pressure (without a decrease in temperature) they pass into a liquid state. This property makes it possible to store and transport liquefied gases in containers and cylinders with the conveniences typical for gases;
  - vapor pressure of liquefied gases in the cylinder depends on the ambient temperature;
  - in the gaseous state, hydrocarbons are 1.5 ... 2.0 times heavier than air, due to which liquefied gas vapors accumulate in recesses, pits and other lowest points of the room, making it difficult to weather them;
  - low viscosity favors gas leaks;
  - low explosive limits: at a content of 2% liquefied gas in the air (lower explosive limit), the resulting gas-air mixture becomes explosive and continues to be so until the concentration of liquefied gas in it increases to 10% ( upper limit explosiveness); when the content of liquefied gas in the air is more than 10%, the gas-air mixture is not explosive, but combustible;
  - when the outside temperature rises, the liquefied gas in the cylinder expands significantly, therefore, the heating of the gas cylinder above a certain temperature (37 ° C) must not be allowed;
  - Liquefied gases are odorless. For timely detection its gas leaks
  odorize, i.e. add a special substance - an odorant;
  - all hydrocarbon gases, replacing oxygen in the air, have asphyxiating properties.
  Reducing the oxygen content to 22% is deadly;
  - ingress of the liquid phase of liquefied gas on open areas skin leads to strong
  frostbite.

• Propane as a liquefied gas can be used at temperatures down to -30°C. At a lower temperature, propane vapor condenses, and gas supply stops at a temperature of -42°C. Vapors of technical butane begin to condense at -0.5°C. This property makes it impossible to use butane in winter period in cylinders installed outdoors. The gas remains in the cylinder in a liquid state, there is no evaporation, and, consequently, there is no necessary pressure in the cylinder, at which the gas pressure regulator can provide the minimum allowable gas flow.

FUEL SUPPLY

• The user must complete the gas heater with a 50 kg gas bottle(s) filled with propane. It is unacceptable to use gas cylinders of smaller capacity.
• The amount of propane available for use is determined by two factors:
  - the amount of propane in the cylinder (cylinders);
  - temperature of the cylinder (cylinders).
• When operating the heater at low temperature ambient or maximum heat output, gas cylinders may cool down due to an increase in the gas evaporation rate, which can lead to a pressure drop in the cylinder (s) and poor combustion. In this case, it is recommended to do parallel connection cylinders, as shown in Figure 4, using a special "tee" (purchased at an additional cost).

Fig.4 Parallel connection of gas cylinders

• Below is the number of 50 kg cylinders required for the operation of a gas air heater with a thermal power of 30 kW.

MAKE CONNECTIONS

1. Provide a propane supply system, see section “Fuel. Providing fuel."
2. Check for a gasket under the reducer union nut. Connect the reducer to the gas cylinder using the union nut (Figure 5), tighten the nut with a wrench. Important: When locating cylinders outdoors, install the reducer so that the adjustment knob (if any) is turned down, this will prevent damage to the reducer due to adverse weather conditions.

Fig.5 Connection of a reducer with a gas cylinder.

Important: To increase the safety of operation of gas air heaters, it is recommended to install on the gas supply line "gas fuse", purchased for an additional fee, shutting off the gas supply when a leak occurs in the gas supply system. When connecting heaters to the gas supply system, install a gas fuse between the fittings of the reducer and the gas supply hose to the heater. When PREPARING TO POWER ON, press the guard head gas fuse and fix it in the lowest position (this operation must be done every time after the gas pressure drops - for example, after replacing an exhausted gas cylinder). If the gas fuse has tripped, cut off the gas supply and stopped the air heater, this means that in gas hose there was a leak. In this case, perform the operations described in the MAINTENANCE section. A LEAK. After repairing the gas leak during the PREPARATION FOR START-UP, return the gas fuse into the working position by pressing on its head - gatehouse ..
3. Connect the hose to the heater power connector (Fig. 6). Lock the connection with a wrench.

Fig.6 Connecting the hose to the heater.

4. Open the valve on the gas bottle.
5. Set the reducer handle (if the reducer is adjustable) to the gas pressure value
corresponding to the operating range of the heater (see section TECHNICAL
SPECIFICATIONS).
6. Make sure there are no gas leaks by using the place of soaping - applying liquid
soap or soap solution to the joints.

Warning! Never use an open flame to find a leak.
Use the soaping method - applying a soapy solution to all joints.
The bubbles that form will show where the gas is leaking.
Take immediate action to repair any leaks.

7. Close the gas cylinder valve.

REPLACING THE GAS CYLINDER

Change the gas bottle(s) only where there is no open flame. Extinguish all sources
flames, including those on duty. Use only propane, 13R.
The sequence of operations when replacing a gas cylinder:
1. Tightly close the valve on the gas cylinder(s) to be replaced.
2. Disconnect the reducer from the cylinder(s).
3. Connect the reducer to the new gas bottle. Tighten the union nut tightly.
4. Check all connections for gas leaks.

Principle of operation

FUEL SUPPLY

The gas pressure regulator (reducer) is attached to the propane tank, see the section “FUEL. MAKING CONNECTIONS”, or can be mounted on the body of the heater itself. When the gas cylinder valve is opened, gas is supplied to the combustion chamber nozzle after opening the gas valve, which has an electromagnetic principle or is opened manually by pressing the valve button.

AIR SUPPLY SYSTEM

The engine rotates the fan, under the action of which the air moves inside the combustion chamber, forming a gas-air mixture, and around it. After combustion of the gas, a stream of clean hot air is formed at the outlet of the heater.

IGNITION SYSTEM

Gas ignition comes from spark discharge between the electrodes - igniters, the voltage to which is automatically supplied from the control unit when the heater is turned on or from the ignition element when its button is pressed manually.

FLAME CONTROL SYSTEM

This system turns off the heater if the flame goes out. At the same time, gas combustion and heat generation stop, however, the fan motor continues to operate, providing purging and cooling of the combustion chamber. The basis of the control system is a temperature sensor, the signal of which shuts off the gas supply valves.

Ventilation Requirements

Before starting the heater, it is necessary to ensure, and in subsequent use, maintain the flow area of ​​fresh outside air through the two ventilation openings (for air inlet and outlet) (S windows) in accordance with the formula:
S window = W max × 25 (cm3);
where W max - maximum thermal power heater of this brand, kW.

The minimum total window area is 250 cm3.

One vent should be at floor level, the other under the ceiling. non-compliance minimum requirements room ventilation can result in CARBON MONOXIDE POISONING. Ventilation of the room with fresh outside air must be ensured before starting the heater.

Terms of use

Check the completeness and accuracy of compliance with the requirements and prescriptions set out in the "Safe Operation Standards" section of this Manual. Do not use the heater if at least one of the requirements is not met.

The Bosch wr 10 2p geyser can operate on both natural and liquefied gas, i.e. balloon. It is equipped with triple protection: a thermoelement for controlling the ignition flame, controlling the draft of gas combustion products, and a temperature limiter that protects the column from overheating.

The model is also equipped with a reliable flame modulation system. This means that the column automatically adjusts the heating to the required fluid flow. If you are washing dishes in the kitchen, and someone decides to wash in the shower, the water temperature will be the same, both in the kitchen and in the shower. The power of the liquid at the outlet is also automatically regulated when the water pressure in the water supply changes.

Before turning on, according to the operating instructions for the Bosch geyser, you need to make sure that there is draft in the chimney. this can be done by bringing a lit candle or match to the chimney. If the flame deviates towards the chimney, then everything is in order with the draft, and the device can be turned on.

If there is no draft, you should find out the cause and clean the air duct, or seal the seams of the air duct pipes if a loose fit of its parts is found. When the column is operating, make sure that the window or window is ajar, the door in the room where the column is installed should not close tightly.

This ensures the natural movement of air and the flow of oxygen, the unit burns during operation a large number of oxygen. Failure to comply with these requirements can result in carbon monoxide poisoning. It should also be remembered that when the column is running, you cannot turn on the fan or air conditioner, this disrupts the outflow of carbon monoxide through the chimney.

On the front panel of the apparatus, on the left, there is a slider that regulates the power, on the right, a toggle switch for the volume of liquid, above them there is a viewing window. Never get too close to it to avoid burns.

Gas column control panel Bosch WR 13-2 P

If starting for the first time or after a long period of inactivity, some air may accumulate in the dispenser pipes. To remove it, open and close the hot water tap several times, at intervals of about a minute, until it is completely removed.

When first turned on, open the gas and water supply valves, open the faucet hot water to make sure fluid is coming in.

The Bosch column has a piezo ignition system, the button of which is located at the bottom left. To turn it on, you need to move the slider from the left extreme position to the ignition position, indicated by an asterisk. Drown it and at the same time press the piezo ignition button several times until the ignition flame appears.

At the same time, loud clicks are heard, they should not be scared, as it should be. If the pilot flame ignites, release the slider button, if ignition does not occur, repeat the entire procedure again. The unit may not start if, after a long period of inactivity or when first turned on in gas pipes air got in. To remove it, hold the slider button in a recessed state until all air is removed.

Once the unit has turned on, set the power you need using the same slider. The extreme right position provides maximum power, while increasing gas consumption. With the help of a round knob, the required flow of liquid and its temperature are set.

By turning the knob clockwise, you reduce the flow and increase the temperature, by turning it counterclockwise, on the contrary, the flow increases, the temperature decreases. High temperature setting increases gas flow and scale formation in the heat exchanger.

The pilot flame burns constantly, and the main burner ignites at the moment the hot water tap is opened. The shutdown occurs when you turn off the hot water tap. To turn off the unit completely, move the power regulator slider to the extreme left position, the pilot flame will go out ...

If there is a risk of water freezing in the appliance, for example, in a country house in winter, the water must be completely drained from it. To do this, close the water and gas supply valves, open the taps on the mixer.

Remove the housing cover by unscrewing a few bolts to access the water unit. Remove the bracket in the form of the letter “P” from the filter housing on the water fitting and remove the plug, which is located immediately behind the bracket. Wait a while until the liquid is completely drained.

To prolong the life of the device, it is necessary to carry out regular maintenance, at least once a year. Clean the inside of the column from dust and soot, rinse the heat exchanger from scale. At the same time, you should be aware that all work with gas equipment should be carried out only by a specialist.

After all preparations have been made Bosch boiler Gaz 6000 for launch, after pre-launch preparation, which includes checking expansion tank, stop valves, filters, checking the pressure in the gas line, the tightness of the connection of all joints, the boiler is connected to the electrical network.

After powering up to the mains, the “attention” icon appears on the electronic display, which is located on the front panel of the unit. Next, press the power button on the front panel, located near the upper left corner of the electronic display. Above the display is a magnetic instruction that allows you to easily change the settings of the unit.

When turned on, within two seconds, the boiler electronics conducts self-diagnostics, all sensors are checked and switched to blocking mode. The display shows the current temperature and status code. Next, it is necessary to adapt the fan speed to the length of the chimney to which the unit is connected.

This operation is performed by simultaneously pressing and holding three buttons - "+", "-" and "back". The mode is set in accordance with the parameter specified in the instructions for the device - we set the second service level, confirm the action with the "ok" button, holding it until square brackets appear on the display.

In addition to the display, in the lower right part, a pressure gauge is mounted showing the pressure in the system, the normal pressure is in the green zone. The red zone indicates the pressure below and above the nominal pressure when the protection is activated and the unit is turned off.

Bosch THERM 4000

You can increase the pressure using the blue tap by unscrewing it counterclockwise until the pressure gauge needle returns to the blue zone. When the pressure increases, the liquid will be discharged through the corrugated tube at the bottom of the unit and the pressure gauge will return to its normal position.

The boiler can operate in two modes, liquid heating and heating mode, which of the modes is active, shows the icon on the display.

The mode is selected by pressing the "+" or "mode" button. After selecting the mode, set desired temperature, then press "ok" - confirm the choice, after which the up and down arrows appear on the display, use the "+" and "-" buttons to set the required heating temperature. To save the selection, press the OK button and hold for a couple of seconds.

If it is necessary to set the heating operating mode, select it with the “-” button, confirm by pressing “OK”. The choice of temperature and saving the choice is carried out in the same way as when setting the water heating temperature. The fire icon that appears on the display indicates that the turbine has turned on and heating has begun.

When the set temperature is reached, the fire icon will disappear, after falling, when the boiler turns on again, it will appear again, this will happen cyclically throughout the entire operation of the boiler with the specified parameters. In the event of any malfunctions in the operation of the Bosch Gaz 6000, for example, in the absence of gas or water supply, the protection will work and an error message will appear on the display.

The interpretation of the error and the actions to eliminate it are described in the instructions for the boiler. After identifying and eliminating the cause, you must confirm the action on the display by pressing and holding the "ok" button for a few seconds. After that, the boiler automatically starts up again.

The unit is protected from freezing if the pump is running and fluid is circulating through the heating system. If the boiler needs to be turned off, then antifreeze is added to the heating liquid, and water is drained from the hot water supply, as a rule, this work is done by a specialist. Maintenance is also carried out by a specialist, since the unit is a rather complex device associated with high blood pressure and gas.

INSTEAD OF RD 34.35.518-91

This Instruction Manual gas protection(hereinafter referred to as the Instruction) is mandatory for employees involved in the adjustment, technical and operational maintenance of gas protection devices in the power systems of the Russian Federation.
The Instruction describes the principles of operation and provides the designs and technical data of gas and jet relays used in power systems, as well as methods for technical and operational maintenance of protection with these relays. Information is given about the shut-off valve and the oil level control relay in the expander, since these elements are functionally part of the gas protection circuits. The description and technical data of the PG-22 and PGZ-22 relays that have expired and are morally obsolete are excluded from the Instruction, which are recommended to be replaced with relays of modern designs. Also excluded is an appendix on the replacement of reed switches in a relay made in Germany in connection with the termination of the activity of NTTM "Poisk" - a manufacturer of elements of the reed switch holder. The Instruction includes a description of the design and instructions for commissioning and maintenance during operation of the new domestic gas relays RGT80 and RGT50 and the jet relay RST25.
The Instruction has been amended in accordance with clause 5.3.22 of RD 34.20.501-95 and individual comments of power systems.
With the release of this Instruction, the "Instruction for the operation of gas protection: RD 34.35.518-91" becomes invalid. (M.: SPO ORGRES, 1992).

1 PURPOSE OF GAS SHIELD
Typical damages of an oil-filled electrical apparatus - a transformer, an autotransformer, a reactor (hereinafter referred to as a transformer) include short circuits (short circuits) between the windings, coil short circuits, "fire" of the steel of the magnetic circuit, oil leakage from the tank, malfunctions of the oil-filled contactor of the tap changer of the voltage regulation device under load (RPN), etc.
Almost all damages inside the tank of an oil-filled electrical apparatus are accompanied by the release of gas as a result of the decomposition of oil or other insulating materials under the action of partial electrical discharges, increased heating, and an electric arc. During a short circuit, an accelerated flow of oil or its mixture with gas from the tank of the apparatus into the expander occurs. During operation, it is also possible to reduce the oil level or release gas for various reasons.
Contactor malfunction can be caused by damage to the insulation, weakening of the mechanism springs, aging of ceramic power contacts, which leads to slowdown and fuzzy switching. A protracted arc is accompanied (taking into account the small volume of oil in the contactor tank) by the rapid decomposition of the oil. A jet of oil mixed with gas is directed from the contactor tank to the expander.
The protection that reacts to these damages is called "gas". This protection is carried out with the help of so-called gas and jet relays.
Gas relays are designed to protect transformers with an expander from damage inside the tank, in which there is a release of gas, a decrease in the oil level, or the occurrence of an accelerated flow of oil from the transformer tank to the conservator.
Jet relays are designed to protect the contactors of oil-filled transformer tap changers from damage, accompanied by the occurrence of an accelerated flow of oil from the contactor tank to the expander.
In case of internal damages in the transformer, even the smallest ones, gaseous decomposition products of oil or organic insulation are released, which ensures the operation of gas protection at the very beginning of the onset of a gradually developing damage. In some cases of dangerous internal damage to transformers ("fire" of steel, interturn short circuits, etc.), only gas protection is in effect, and electrical protection transformers do not work due to insufficient sensitivity.

2 BRIEF DESCRIPTION OF GAS AND JET RELAYS

2.1 Basic design and principle of operation
Gas relays have a hermetically sealed case installed in the oil pipeline between the transformer tank and the conservator. Figure 1 shows a simplified sketch of a design option for such a relay. The reacting relay unit has three main elements: signal 1 and shutdown 2, 3 (elements 1 and 3 - floats, 2 - pressure plate), each of which works under certain conditions.

Picture 1 - Gas relay

Under normal operating conditions, the relay case is filled with oil, and the elements take up a position in which the contacts they control (not shown in the figure) are open. With a slight gas formation in the transformer tank, the gas passes through the oil pipeline into the expander, accumulating in the upper part of the relay housing, where the signal element 1 is located.
When a certain amount of gas accumulates in the relay, the oil level in it decreases, the float of the signal element 1 falls under the action of gravity and the signal contact closes; similarly, the signal element of the relay is triggered when the oil level in the relay drops for other reasons.
With a further decrease in the oil level, when the relay housing is emptied by more than half, the float of the disconnecting element 3 also falls under the action of gravity and the disconnecting contact closes.
In the event of a short circuit inside the transformer tank, under the action of an electric arc, a rapid decomposition of the oil occurs and the flow of oil or a mixture of oil and gas rushes at high speed from the tank to the expander (arrow in Figure 1). Under the influence of this flow, plate 2, which has an adjustable oil flow rate setting, deviates to a certain angle and the tripping contact closes. Depending on the type and development of the transformer damage, sequential or simultaneous operation of the signal and tripping elements of the relay is possible.
With rapid gas formation and sharp jolts of oil, the contacts may rebound after operation, so the gas relay must act to turn off through the intermediate relay according to the self-holding scheme.
Jet relays, unlike gas relays, do not have floats and their contacts are triggered to turn off the transformer under the action of a pressure plate, which, similarly to a gas relay, has an adjustable setting for the oil flow rate. The design of the jet relay usually provides for fixing the pressure plate after actuation in the final position until it is manually released, which increases the reliability of the relay operation under conditions of a less stationary flow of an oil-gas mixture compared to the flow in a gas relay.
The use of jet relays that do not have floats is due to the peculiarity of the operation of the contactors of the on-load tap-changers. V normal operation contactor under the influence of an electric arc at the moment of switching, a small amount of oil is decomposed and gas is released from it, which passes through the pipeline into its expander or into the compartment of the common expander and then through it Airways goes out into the atmosphere. It is normal for a small amount of combustible gas to escape from the oil during contactor operation.

2.2 General instructions for mounting the relay
To provide correct operation gas protection, it is necessary to follow the rules for installing and mounting the transformer and relay.
The diameter of the through hole of the connecting flange of the gas relay must correspond to the inner diameter of the pipeline from the tank to the conservator. The jet relay must be installed in an oil line with an internal diameter of 25 mm and as close as possible to the contactor. Diameter mismatch can result in failure of actuation, such as failure of the lower float to actuate when oil is lost, or a change in the oil flow rate of the pressure plate actuation compared to the set point.
The gas relay must be installed in the pipeline between the tank and the cock to shut off the oil in the pipeline. The arrow on the relay cover must be directed from the tank to the expander.
The cover of the transformer (reactor) must have a rise towards the expander and, therefore, to the gas relay of at least 1%, and the oil line to the expander - at least 2%. To lift the transformer cover from the side of the expander, metal linings are used under the transformer rollers.
The specified rise is carried out so that the gas released from the oil does not accumulate under the tank cover, but, being at the highest point in the tank, passes through the oil pipeline to the gas relay. After filling the upper part of the relay housing, the gas that continues to flow passes into the expander and then through the breathing tube into the atmosphere.
To ensure proper operation of the jet relays, the rise of the oil line from the contactor to the expander should be 2-4% to the horizontal.
When mounting the relay, the gaskets between the flanges of the oil pipeline and the relay and under the relay cover must not protrude into the oil pipeline and the relay housing. All bolts must be securely tightened. Under the safety bolt (one of the bolts connecting the cover to the relay housing, usually its head is painted red), a toothed washer should be laid with teeth towards the relay cover. After installing gas relays with a control (testing) button on the pipeline, it is necessary to remove the transport gasket from under the protective cap of the button.
To ensure reliable operation of gas protection in case of damage in the transformer, cables from gas and jet relays should be laid on the transformer in a protective metal hose. In order to reduce the places of possible decrease in insulation resistance, cables should be laid directly from the relay outputs to the terminals of the transformer protection panel. The insulation of the cables used must be oil-resistant.

2.3 Features of the gas relay RGChZ-66
The main design feature of the RGChZ-66 gas relay is the use of metal cups instead of floats. Like all gas relays, it (Figure 2) has a hermetically sealed case in which there are three reacting elements: the upper one - cup 1 - signal and two lower disconnecting ones - cup 2 and a trip plate 11. When the relay is filled with oil, the contacts located inside cups remain open, since each cup is pulled up to the stop by a spiral spring 5. When a small amount of gas is released from the transformer tank, it accumulates in the upper part of the relay, displacing the oil. In this case, the oil in the cup of the relay signal element remains, and under the action of the mass of this oil, the cup rotates around its axis 12 down until the contacts close.

1, 2 - cups; 3 - contact; 4, 9, 16 - racks; 5 - spiral spring; 6 - assembly ring; 7, 8 - holders;

10 - bracket-shaped stand; 11 - disconnecting plate; 12, 13 - axes; 14 - gasket; 15 - ledge; 17 - lever;

18 - plate; 19, 20, 21, 22 - screens; 23 - crane; 24 - sight glass; 25 - cork; 26 - terminal box
Figure 2 - Gas relay RGCHZ-66

The disconnecting elements (cup and plate) are located in the lower part of the relay housing, the plate is installed against the inlet of the oil pipeline from the side of the transformer. It is an element that reacts to the oil flow rate in the oil line, and the cup is an element that reacts to the almost complete emptying of the relay housing from oil. Both of these elements act on the same contact, and the plate works independently of the cup. If the transformer is damaged, accompanied by rapid gas formation, the pressure in the tank rises, and the oil is forced out of the tank into the expander. When the oil flow rate is equal to or greater than the relay setting, by the force that occurs on the plate 11, the latter rotates around the axis 13 together with the rack 16 and the moving contacts until they close with the fixed contacts. In this case, the cup of the disconnecting element can remain at rest. A little later, the signal element may also work if the released gas rises from the transformer tank and fills the upper part of the gas relay housing.
In case of emergency oil maintenance, when Bottom part the relay housing is emptied, the disconnecting element (cup) will work in the same way as the signal cup - with contact closure. In this case, the plate also deviates, since the wall of the cup, when moving, presses on the protrusion 15 of the rack 16, to which the plate is attached.
In the upper part of the relay case, through sight glasses 24 are embedded with divisions (in cubic centimeters), which allow determining the volume of accumulated gas.
A cock 23 is installed on the cover of the relay housing for sampling gas and venting air from the relay; terminal box 26 is used to connect the control cable. The relay cover has an arrow indicating the direction to the expander. There is a hole in the bottom of the terminal box to drain the moisture that collects in it. A plug 25 is provided in the lower part of the relay housing for draining contaminated oil. The reacting relay unit is attached to the case cover with the help of racks on which all relay elements are mounted.
Each cup on the side of the oil flow inlet is closed by cylindrical half-screens 19, 21. Screens 20 and 22 are installed above the cups to reduce the loss of oil sludge to the bottom of the cups. The screen 22 has a slot for moving the plate 11.
The relay can have one of three fixed oil speed settings: 0.6; 0.9; 1.2 m/s. The required setting is provided by installing one of the three calibrated plates 11.
The response time of the high-speed element at an oil flow rate of 1.25 does not exceed the setting specifications 0.2 s (practically - about 0.1 s).
The signaling element of the relay is activated when the upper part of the relay is filled with gas with a volume of approximately 400 cm.
The relay contacts are designed to make and break the AC circuit and direct current up to 0.2 A at a voltage of 220 V.
The relay insulation withstands a test voltage of 2000 V at 50 Hz for one minute.
Working range of ambient temperature - from -40 to +40 °С. The limiting oil temperature is +100 °C.
The weight of the relay is about 12 kg, the diameter of the flange through hole is 80 mm.

III Principles of preparation.

cooking typology.

The types of preparations you can make with this machine are described in this manual:

Bakery and confectionery products. Professional bakery with:

Convection: bread is made with hot air Convection and humidity: bread is made with hot air and humidity.

Gastronomy. Professional food preparation with:

1.steam: cooking is done with steam

2. convection: cooking is carried out only with hot air without steam

3. convection + steam: cooking is done with hot air and steam

1.1 Basic cooking methods:

Attention:

A. Before any operation, heat the oven 30˚ above the desired temperature. This allows you to achieve the best results.

B. use more high temperatures than needed for certain foods cause uneven cooking

C. Baking bread and confectionery: do not use trays over 20 mm high. and avoid food touching each other on the tray.

convection cooking

Humidity: not used

V convection ovens cooking is carried out by hot air, which circulates through the cooking chamber. This allows you to cook uniform food, due to the distribution of heat evenly.

Homogeneous baking is guaranteed even at full load. Products are well baked not only inside, on the surface, but also a golden crust is obtained.

The main advantage is the ability to cook at the same time different kinds products without mixing flavors.

convection + humidity

Temperature: 0 to maximum

Humidity 0% to 10˚0%

Cooking is carried out with hot air with different percentages of humidity, according to the type of food.

Steam cooking

Temperature from 105 to 115˚С

Steam cooking.

The use of ventilation steam is expected every time the effect of boiling (cooking) is needed.

nutritional ingredients, appearance and the weight of the products remains unchanged. With this type of cooking, the food does not lose liquid.

Cooking is done with a combination of hot air and steam. Cooking time has been reduced. Products remain moist and almost do not change in weight.

1.2 Other cooking times.

The ability to set the temperature and steam according to your desire allows you to implement other types of cooking:

Recovery (regeneration) of products

Temperature: 0 to maximum

Steam: 0% to 100%

Low temperature cooking

Temperature below 100˚С

Steam from 0% to 100%

Cooking changes.

Temperature

Precise temperature control guarantees proper preparation products, both outside and inside.

The temperature is lower than it should be drying, not cooking food

The temperature is higher than it should brown the surface, while the inside remains uncooked (sometimes this is necessary, for example with meat products).

Its change depends on the amount of products placed in the oven. More products require more time and vice versa.

Less cooking time than required does not cook food well.

More time burns products.

The combination of temperature and steam allows you to cook different types of food, depending on the type of food you want to cook.

The ability to set the temperature and steam as you wish allows you to cook in the trivalent way: convection, steam and a combination of steam and convection.

If you set the steam to maximum and the temperature is around 105°C, steam cooking is possible. For example, vegetables.

Extraction of humidity by the Venturi system.

This function is used when you need to dry food in the oven. We dry the products in a chamber by extracting moist air with a venturi system.

With the extraction of moisture, foods become crispy and crumbly on the outside (such as bread and meat), while the inside is dry with a uniform texture.

If the food itself is damp, you can dry out that moisture with a venturi system. Thus, the climate inside the chamber remains always dry.

Fan stop.

This function is needed for the products to rise inside the chamber.

Moreover, it is needed to delay the start of cooking.

Number of products

The amount of food affects the cooking time.

The more products, the more time cooking and vice versa.

Use of trays - wire grate

Aluminum trays: pastries, not frozen bread

Stainless steel trays: first course, meat, fish, potatoes

Wire grates: hot dogs, sausages, sausage, frozen bread, frozen pizza

This manual is not a professional setup manual, this is a household HBO operating manual.

Vacuum (for a carburetor) or electronic (for an injector) two-stage gearbox is designed to operate on liquefied petroleum gas fuel (propane-butane). From a cylinder gas under pressure of 16 atm. enters the gas valve, where it is cleaned from resinous substances and mechanical impurities. Further, the purified gas passes into the first stage of the reducer, where the pressure is reduced to 2 atm., and then to the second, where it is reduced to 0.5 atm.

Under the action of vacuum created in the collector of a running engine, gas from the cavity of the second stage of the reducer enters the tee-dispenser. From the tee-dispenser through a mixing device (spacer, mixer or nozzles) to the carburetor chambers or injection device, where a homogeneous combustible mixture is formed, which enters the engine cylinders. The coolant from the engine block through the adapter enters the lower reducer pipe, heating the gas and improving its evaporation.

The procedure for launching HBO into the operation of a carburetor car

- Starting a cold engine is necessary (at temperatures below + 7-10 degrees) and preferably, in principle, to produce on gasoline, followed by warming up to a temperature of 40-50 degrees. Then the switch (switch in the cabin) is moved to the middle position, gasoline is produced from the float chamber. As soon as the car starts to work intermittently, move the switch to the "gas" position. It is allowed to start a warm engine on gas.

- The idle speed is regulated by a screw located on the gearbox housing. The gas flow rate is regulated by screws on the tee-dispenser. After the initial adjustment made by the master of the installation center, the flow-dynamic characteristics can be improved as follows: screw 1 regulates the gas supply to the first chamber of the carburetor, which affects the dynamic characteristics of the machine during acceleration and partial loads. Accelerate the car to 80 km / h, and if the “reception is good”, tighten the screw 1 half a turn, repeat the procedure until the car starts to “dumb”, then unscrew the screw 1 a quarter of a turn back. Screw 2 controls the second chamber of the carburetor, the degree of filling of which determines the throttle response at full loads. To adjust the second chamber, accelerate the car over 90 km/h and repeat the procedure described above. Because the density of the gas (kg/l) is less than the density of gasoline, gas is consumed by 10-15% more. When parking overnight, the car should be converted to petrol. To do this, increase the engine speed to 3000-3500 rpm, switch the switch (switch) to the “gasoline” position, bypassing the development, and wait for the float chamber to fill with gasoline.

The procedure for starting an injection car

The injection car is equipped with a two-position automatic switch (switch) gas-gasoline. When the switch is in the petrol position, the machine runs on petrol only (the red warning light on the petrol sign is on). To convert a car to gas, you need the following:

1. Switch the switch to the gas position.

2. Start the engine and warm it up to a temperature of 40-50 degrees. At the same time, the lamp of the petrol symbol on the switchboard lights up red, the green lamp on the gas symbol flashes (rev standby mode).

Z. To switch to gas, you must press the accelerator pedal and gain 2500 rpm and release it sharply. The car switched to gas (the green lamp on the gas symbol is on, the red one is off).

Basic safety requirements

- In the case when the power is not satisfied, increased consumption, problems with idling, self-adjustment of the car is prohibited (incorrect regulation can cause cotton (injector only) and, as a result, failure of the mass air flow sensor, air filter housing, intake manifold). In this case, you should contact the service station.
- Injector: it is forbidden to operate the car until the gas from the cylinder is completely depleted (a lean mixture can cause popping). It is recommended to leave 10%.
- It is recommended to change the air filter at least every 5-6 thousand km.
- It is necessary to drain the condensate (plastic screw-plug on the gearbox housing) every 1000 km, but no later than 1500 km.
- Injector: if cotton occurs, it is necessary to switch the switch to the petrol position (only the red lamp will be on) and come for a consultation to the service center.
- Injector: it is forbidden to operate the car on gas when there is no gasoline in the gas tank. Airlock may lead to failure of the fuel pump (minimum balance of 7-10 liters).

- When the car is running on gas, the petrol valve is in the closed position (OFF), therefore, if the electrical system fails, both the gas supply and gasoline are interrupted. In this case, it is necessary to check the HBO fuse and, if it is faulty, replace it. If the fuse is good, the electrical system is checked as follows:
when the switch is switched to the “gas” position (or the “gasoline” position), the corresponding solenoid valves should make a characteristic click. If this does not happen, the system is faulty. In this case, it is necessary to transfer the switch to the middle position (development), screw in the screw for the mechanical opening of the gas valve and come to the technical center. It is strictly forbidden to keep the gasoline valve open when the electrical system is working, because this leads to the simultaneous supply of gas and gasoline to the engine, which is unacceptable.
- for the optimal composition of the air-fuel mixture, it is recommended to change the air filter at least after 7000 km of run.
— It is recommended to use an air filter with as little airflow resistance as possible.
- replace spark plugs every 10,000 km (a spark plug producing less than 3-4 pulses does not ignite the gas-air mixture in the engine cylinder).
- drain the condensate from the gearbox every 1500 km by unscrewing the screw on the gearbox housing.
- After every 500 km driven by a car on gas, drive 15-20 km on gasoline, which contributes to the deposition of lead oxide on the valves and seats, preventing their additional wear, and also reduces wear on the diaphragms and clogging of the carburetor.

General safety requirements

— Carry out a daily check of the coolant level (antifreeze).
— In case of detection of leaks or damage to HBO, close the main valve of the multivalve on the cylinder and come to the service center. It is forbidden to tighten nuts and connecting pipelines under gas pressure.
- It is forbidden to start the car on gas with the choke removed, this will shorten the life of the main membrane or cause a rupture.
- It is forbidden to leave a car fully filled with gas in the sun without first using a few liters.
- It is forbidden to operate HBO if external mechanical damage is detected.
- It is forbidden to continue driving the car on gas if you detect the smell of gas in the cabin.
– When installing and dismantling any HBO units on your own, as well as when preserving a car for long term(more than a month), it is necessary to close the filling and main valves on the cylinder multivalve.

Successful operation!

You need to know that in the cylinder the maximum allowable

Every motorist wants to drive more and pay less. Such unique opportunity gives us HBO 4 generations. In addition to saving, it also has a number of positive advantages. The 4th generation gas equipment system is very similar to gasoline. Distributed injection is provided separately to each engine cylinder. The driver hardly notices the transition from one type of fuel to another. It means,

An analysis of the features of gas-balloon equipment allows us to assert that its design is simple and reliable in operation, fully ensures fire and explosion safety. gas fuel can be used on a par with gasoline fuel if strict observance of safety precautions and maintenance rules.
