Device and repair of the solenoid valve AOGV Rostov (Publication date 08/18/2016)

60 years

By popular demand, we publish the device and operation of the solenoid valve, which are equipped gas boilers AOGV Rostov. This device was designed and put into production by the plant back in the 50s. The very fact that in the 21st century we still need to carefully study the operation of this device only says that the device of the 50s turns out to be much more reliable than anything that has been proposed by "progress" over the past 60 years. And this is connected, as I think, only with the fact that there is still not enough electricity for everyone. And even if it is enough, then no one guarantees 100% stability in supplies anyway. Therefore, devices that ensure the operation of gas boilers, regardless of whether there is electricity in the network or not, have always been, are and will always be advanced in the household. The most best service what security? - the most inconspicuous and unobtrusive. So these devices serve us for years without drawing our attention to themselves at all, without requiring special qualifications, nor special means for diagnostics, no service, no time, no money. Once again, I emphasize - back in the 50s ...

Basic moments

In order to immediately begin to have a grip, first consider the solenoid valve in the state when it is installed on the boiler. And later we will remove it and examine it, holding it in our hands. All the elements we need are numbered in the photo. We will need a grasp in order to quickly understand what kind of boiler you have, even if you have lost your passport. Quickly find out what needs to be replaced. Order all this and go do other things.

Let's look at the numbers:

6. Gas supply pipe to the boiler. If you remove this plug, in the depths we will see a regular grid (circle). This fitting is threaded inside or outside. External thread diameter 3/4"" for AOGV boilers from 17 kW to 35 kW. For boilers AOGV-11.6 - internal thread 1/2 "", - which we observe here. Further...
5. Gas outlet fitting to the draft control tee. From this tee, the gas has outlets: down, to the boiler igniter, and up, to the gas emergency shutdown pipe in case of overheating.
4. Plug of the gas part of the solenoid valve. It is located on the back side of it is not visible in this photo.
3. Branch pipe for connection to the gas valve temperature controller. This connection is always shorter than the gas supply connection (6). And it always has a thread only with an internal diameter of 1/2 "".
2. Contact for connecting the gas control thermocouple to the windings of the electromagnetic part of the device. By quickly attaching a tape measure from the nut screwed onto the contact (3) and measuring the distance along the thermocouple to its first bend, comparing this length with the lengths of thermocouples for AOGV Rostov, you can quickly determine which thermocouple is installed on your boiler.
1. Solenoid valve button for manual release of gas to the igniter. If this button "looks" to the side, and not up like Zhukovsky's, then this is definitely Rostov.

Next, we separate the solenoid valve from the boiler and check the numbers again. In the second photo, the plug of the gas part of the valve (4) is already clearly visible. And there is a noticeable difference in length between nozzles 6 and 3. And it is clear how to install the valve in its place - contact (3) for connecting a thermocouple should "look down".

If this is clear, we proceed to the analysis of the solenoid valve for gas boiler AOGV Rostov

For the convenience of the penetration of visual material into the brain, we made inscriptions on the proposed photos. This greatly simplifies all the main comments, since it is better to see everything once than to talk in vain. Go! We unscrew the four screws from the valve cover and separate the top from the bottom. Before us is the electromagnetic and gas parts of the device. I even somehow find it difficult to answer the question "Which part is more difficult in terms of device?" Well, most likely, we will start with the electromagnetic part, since it is the main one and controls the situation.


Electromagnetic part of the valve AOGV Rostov

Having thrown off the cover of the electromagnetic part, we will see following construction. In the second photo, we denote its main details with numbers:

1. Electrical part. Here we see two windings and a contact for connecting a thermocouple gas control.
2. Solenoid valve cover.
3. Washer.
4. Stock.
5 Button with a spring, which is put on the stem.


This thing works like this. We press the button 5, thereby pressing the washer 3 to the windings of the electrical part 1. The gas went to the boiler igniter. We kindle the igniter and wait for the gas control thermocouple to heat up and begin to generate EMF. After that, washer 3 "magnetizes" to the winding contacts and remains in such a "sticky" position until the boiler igniter is on and the thermocouple is working. Due to this, the gas part valve remains open and gas enters the boiler. If this does not happen, then either the thermocouples are not in order, or the windings are not energized and the washer 3 cannot stick. Then we replace the thermocouple and the solenoid valve with new ones. Or change the thermocouple and .

The electromagnetic part is connected to the gas rod 4. It is with the rod of the electromagnetic part that we press the valve stem of the gas part to release gas. Further.

We even pulled the rod out of the electromagnetic part so that you could see where it abuts inside the product. It rests against the membrane of the gas part. This is under which there is already gas. It may wear out and it is possible to replace it with a new one. Further.

We take this sealing membrane. Under it we see a plastic lining. This is so that the membrane simply does not pierce with a rod when pressed.


This lining is also easily removed and we finally see the valve stem of the gas section.

It is important that you see the hole for the gas to flow to the igniter. For convenience, we put a paper clip there.

It is impossible to pull the valve out of the gas part - you have to unscrew the nut from the back. When the latter is turned inside out, we see that gas valve inside the gas part is supported by a spring. That is, when you manually press the rod of the electromagnetic part and start the gas to the igniter and the entire boiler, the spring resists. They close the valve in case of blowing out the igniter of the boiler or when the EMF from the thermocouple stops flowing to contact 2.


We take out the valve and see that this is the simplest design without subtleties.

By the simplicity of engineering, we can simultaneously judge the reliability of this product. Simple and angry. Mechanical wear is practically non-existent here. Wear of rubber parts is possible, but if lubricated with castor oil, then it is delayed for quite a long time.

That's it. Good luck! Go to section

Overview of the gas boiler AOGV-11.6-3 Economy

Domestic gas heating boiler with a water circuit AOGV-11.6-3 Economy is designed for water heating of residential and office space equipped with water heating systems (CO).

The device works on natural and liquefied gases. The manufacturer supplies devices with nozzles for natural gas. To work on liquefied gas injectors need to be replaced natural gas on nozzles for liquefied.

These units can be installed indoors heating system with expansion tank of membrane type. The pressure in the heating system in working condition (at a water temperature in the heating system of 60 - 80 ° C) should be no more than 1.5 kgf / cm2.

A safety valve must be installed on the riser (outlet pipe), adjusted to operate at a pressure in the heating system of 1.8 ± 0.1 kgf / cm2. To control the pressure in the heating system, a pressure gauge with a measurement limit of 0.4 kg/cm2 must be installed.

The automation unit is an electromechanical device and consists of a unit body, inside which there are valves and a system of levers,
electromagnet, and serves to supply gas to the igniter and burner, regulate the water temperature and automatic shutdown gas supply at:

The extinction of the igniter.

A drop in gas pressure in the network below the allowable one or a gas supply interruption;

No draft in the chimney.

Traction chopper 1 (Fig.1) is designed for automatic stabilization the magnitude of the rarefaction in the furnace of the apparatus, i.e. reducing the effect of fluctuations in the magnitude of the rarefaction in the chimney on the draft in the furnace of the apparatus. For successful operation, the door of the draft breaker 2 must rotate easily on the axis.

The automation of the gas boiler AOGV-11.6 for regulating the water temperature consists of a bellows-bulb 6 assembly installed inside the tank of the apparatus and a system of levers with a valve located in the automation unit.

An adjusting nut 6 (Fig. 2) is fixed on the block body, by turning which you can adjust the automation to a temperature from 50 °С to 90 °С. This change in temperature is caused by the movement of the bellows together with the stem 5 up (down) when the adjusting nut is rotated.

After heating the water to a temperature corresponding to the setting, the gas supply to the burner is automatically reduced, and it switches to the "small fire" mode.

When the water temperature in the apparatus drops (not more than 15 °C) as a result of heat extraction during heating or hot water, the gas supply to the burner is automatically increased. The temperature of hot water in the hot water supply system during its intake should not exceed 60 °C.

Traction automation consists of a draft sensor 4 (Fig. 1) mounted on the tank cover and a cable 8 connecting the draft sensor with a magnetic box.

Fig.3. The ignition device of the boiler AOGV-11.6

1. Thermocouple; 2. Igniter

The ignition device (Fig. 3) is designed to mount the igniter, thermocouple and ignite the main burner. The igniter flame should be around the end of the thermocouple.

The safety of the gas boiler AOGV-11.6 is ensured by automation, the operation of which occurs when:

The extinction of the flame on the igniter;

Lack of draft in the chimney;

The gas supply is cut off or the gas pressure drops below the lower value.

In this case, the gas supply to the igniter and the main burner is automatically stopped.

Preparing the AOGV-11.6 boiler for operation

The room where the AOGV-11.6 boiler is installed must have Free access outside air and ventilation hood at the ceiling and comply with the requirements for the placement of thermal units intended for heating and hot water supply of single-apartment or
blocked residential buildings.

Installation of a boiler unit in a residential building is allowed only if there is a chimney with the removal of combustion products from the apparatus into it. The chimney must meet all requirements.

The chimney channel must have a "living" section not less than the diameter of the device's connecting gas outlet device, be strictly vertical, smooth, even, without turns and narrowings.

The outer surface of the chimney, located above the roof, must be plastered cement mortar. The part of the chimney located in the attic must be plastered and thermally insulated.

Below the point of connection to the chimney of the connecting pipe from the apparatus, a “pocket” must remain in the chimney, at least 25 cm deep, with a hatch for cleaning. In order to ensure optimal working vacuum in the chimney, we recommend that the chimney height be at least 5 meters.

The connection of the AOGV-11.6 boiler to the chimney must be carried out with pipes made of roofing steel. The diameter of the pipes must not be less than the diameter of the draft breaker of the apparatus. The pipes must be pushed tightly without gaps into one another along the course of the combustion products by at least 0.5 of the pipe diameter.

The vertical section of the flue pipe, located directly above the draft arrester, should be as long as possible, but not less than 0.5 m.

Laying connecting pipes through living rooms prohibited. If possible, long horizontal flue pipe lengths should be avoided.

The total length of the horizontal sections of the connecting pipes should be no more than 3 m. (B existing houses length not more than 6 m is allowed).

pipe slope to the side gas appliance must be at least 0.01. Curve radii should not be made smaller than the pipe diameter.

The gas boiler AOGV-11.6 is installed near fireproof walls at a distance of at least 15 cm from the wall. If the apparatus is installed near a non-combustible wall, its surface must be insulated. steel sheet on a sheet of asbestos 5 mm thick, protruding 10 cm beyond the dimensions of the case.

There must be a 1 m wide passage in front of the unit. When installing the unit on wooden floor, the floor should be insulated with steel sheet over asbestos sheet 5 mm thick. The insulation should protrude 10 cm beyond the enclosure dimensions.

To improve the conditions of water circulation in the heating system, it is preferable to install the boiler as low as possible at the level of heating devices (radiators). The expansion tank is located at the highest point of the system. The heating system must be top-mounted.

The surface of the heating devices is determined by calculation. To avoid getting a big hydraulic resistance systems, it is not recommended to underestimate the diameters of pipelines.

AT recent times gasification is proceeding at a rather intensive pace settlements Russia. The main element of the equipment that is installed in each farmhouse, is a gas boiler, the author of this material shares his experience in repairing automation of the AOGV - 17.4-3 gas boiler, popular in rural areas, produced by the Zhukovsky Mechanical Plant.

The device of the gas boiler AOGV - 17.3-3

Its main elements are shown in rice. 2 . The numbers in the figure indicate: 1 - traction chopper; 2 - thrust sensor; 3 - draft sensor wire; 4 - start button; 5 - door; 6 - gas magnetic valve; 7 - adjusting nut; 8 -tap; 9 -storage tank; 10 -burner; 11 -thermocouple; 12 - igniter; 13 - thermostat; 14 -base; 15 - water supply pipe; 16 - heat exchanger; 17 -turbulator; 18 - knot-bellows; 19 - water drainage pipe; 20 - the door of the traction control; 21 -thermometer; 22 -filter; 23 -cap.

The boiler is made in the form of a cylindrical tank. On the front side are the controls, which are covered with a protective cover. gas valve 6 (Fig. 2) consists of an electromagnet and a valve. The valve is used to control the gas supply to the igniter and burner. In the event of an emergency, the valve automatically turns off the gas. Traction chopper 1 serves to automatically maintain the vacuum value in the boiler furnace when measuring the draft in the chimney. For normal operation, the door 20 should freely, without jamming, rotate on the axis. thermostat 13 designed to maintain a constant temperature of the water in the tank.

The automation device is shown in rice. 3 . Let us dwell in more detail on the meaning of its elements. Gas passing through the purification filter 2, 9 (Fig. 3) goes to the solenoid gas valve 1 . To the valve with union nuts 3, 5 draft temperature sensors are connected. The ignition of the igniter is carried out when the start button is pressed 4 . There is a setting scale on the body of the thermostat 6 9 . Its divisions are graduated in degrees Celsius.

The value of the desired water temperature in the boiler is set by the user using the adjusting nut 10 . Rotation of the nut leads to linear movement of the bellows 11 and stem 7 . The thermostat consists of a bellows-thermobalon assembly installed inside the tank, as well as a system of levers and a valve located in the thermostat housing. When the water is heated to the temperature indicated on the adjuster, the thermostat is activated, and the gas supply to the burner stops, while the igniter continues to work. When the water in the boiler cools down 10 ... 15 degrees, the gas supply will resume. The burner is ignited by the flame of the igniter. During operation of the boiler, it is strictly forbidden to regulate (reduce) the temperature with a nut 10 - this can lead to breakage of the bellows. You can reduce the temperature on the adjuster only after the water in the tank has cooled down to 30 degrees. It is forbidden to set the temperature on the sensor above 90 degrees - this will trigger the automation device and turn off the gas supply. The appearance of the thermostat is shown in (Fig. 4) .

How to turn on the gas boiler AOGV

Actually, the procedure for turning on the device is quite simple, and besides, it is described in the instruction manual. And yet, consider a similar operation with a few comments:

- open the inlet gas supply valve (the handle of the valve must be directed along the pipe);

- press and hold the start button. At the bottom of the boiler, a hiss of escaping gas will be heard from the igniter nozzle. Then the igniter is lit and after 40 ... 60 and the button is released. Such a time delay is necessary to heat up the thermocouple. If the boiler has not been used for a long time, the igniter should be lit 20 ... 30 s after pressing the start button. During this time, the igniter will fill with gas, displacing air.

Possible malfunctions of the AOGV gas boiler

After releasing the start button, the igniter goes out. A similar defect is associated with a malfunction of the boiler automation system. Note that it is strictly forbidden to operate the boiler with the automation turned off (for example, if the start button is forcibly jammed in the pressed state). This can lead to tragic consequences, since if the gas supply is interrupted for a short time or if the flame is extinguished by a strong air flow, the gas will begin to flow into the room.

To understand the causes of such a defect, let us consider in more detail the operation of the automation system. On fig. 5 shows a simplified diagram of this system.

The circuit consists of an electromagnet, a valve, a draft sensor and a thermocouple. To turn on the igniter, press the start button. The rod connected to the button presses on the valve membrane, and the gas begins to flow to the igniter. After that, the igniter is lit.

The igniter flame touches the body of the temperature sensor (thermocouple). After some time (30 ... 40 s), the thermocouple heats up and an EMF appears on its terminals, which is enough to trigger the electromagnet. The latter, in turn, fixes the rod in the lower (as in Fig. 5) position. Now the start button can be released.

The draft sensor consists of a bimetallic plate and a contact (Fig. 6). The sensor is located in the upper part of the boiler, near the pipe for the removal of combustion products into the atmosphere. In the event of a clogged pipe, its temperature rises sharply. The bimetallic plate heats up and breaks the voltage supply circuit to the electromagnet - the rod is no longer held by the electromagnet, the valve closes, and the gas supply stops.

The location of the elements of the automation device is shown in Fig. 7. It shows that the electromagnet is closed protective cap. The wires from the sensors are located inside thin-walled tubes. The tubes are attached to the electromagnet using cap nuts. The body leads of the sensors are connected to the electromagnet through the body of the tubes themselves.

Consider the method for finding the above malfunction

Checking when repairing a gas boiler they start with the “weakest link” of the automation device - the thrust sensor. The sensor is not protected by a casing, so after 6...12 months of operation it "acquires" a thick layer of dust. Bimetal plate (see fig. 6) oxidizes rapidly, resulting in poor contact.

The dust coat is removed with a soft brush. Then the plate is pulled away from contact and cleaned with fine sandpaper. We should not forget that it is necessary to clean the contact itself. Good results are obtained by cleaning these elements with a special spray "Contact". It contains substances that actively destroy the oxide film. After cleaning, a thin layer of liquid lubricant is applied to the plate and contact.

The next step is to check the health of the thermocouple. She works hard thermal mode, since it is constantly in the igniter flame, naturally, its service life is much less than the rest of the boiler elements.

The main defect of the thermocouple is burnout (destruction) of its body. At the same time, there is a sharp increase contact resistance at the place of welding (junction). As a result, the current in the Thermocouple - Electromagnet circuit.

The bimetal plate will be lower than the nominal value, which leads to the fact that the electromagnet will no longer be able to fix the stem (Fig. 5) .

How to check the thermocouple of the AOGV boiler

To check the thermocouple, unscrew the union nut (Fig. 7) located on the left side of the electromagnet. Then turn on the igniter and measure the constant voltage (thermo-EMF) at the thermocouple contacts with a voltmeter. (Fig. 8) . A heated serviceable thermocouple generates an EMF of about 25 ... 30 mV. If this value is less, the thermocouple is faulty. For its final check, the tube is undocked from the casing of the electromagnet and the resistance of the thermocouple is measured. The resistance of the heated thermocouple is less than 1 ohm. If the resistance of the thermocouple is hundreds of ohms or more, it must be replaced. The appearance of a thermocouple that has failed as a result of burnout is shown in rice. 9 . The price of a new thermocouple (complete with tube and nut) is about 300 rubles. It is better to purchase them in a store at the manufacturer's factory or use the services of an authorized service center. The fact is that the manufacturer is constantly improving its products. This is reflected in the details own production. For example, in the boiler AOGV-17.4-3 of the Zhukovsky plant, since 1996, the length of the thermocouple connection has been increased by about 5 cm (that is, similar parts manufactured before or after 1996 are not interchangeable). This kind of information can only be obtained from a shop (authorized service center).


The low value of thermo-EMF generated by a thermocouple can be caused by the following reasons:

- clogging of the igniter nozzle (as a result, the heating temperature of the thermocouple may be lower than the nominal one). "Treat" a similar defect by cleaning the igniter hole with any soft wire suitable diameter;

- shifting the position of the thermocouple (naturally, it can also not heat up enough). Eliminate the defect in the following way - loosen the screw fastening the eyeliner near the igniter and adjust the position of the thermocouple (Fig. 10);

- low gas pressure at the boiler inlet.

If the EMF at the thermocouple leads is normal (while maintaining the symptoms of the malfunction indicated above), then the following elements are checked:

- the integrity of the contacts at the connection points of the thermocouple and the draft sensor.

Oxidized contacts must be cleaned. Union nuts are tightened, as they say, "by hand". In this case wrench it is undesirable to use, since it is easy to break the wires suitable for the contacts;

- the integrity of the electromagnet winding and, if necessary, solder its conclusions.

The performance of the electromagnet can be checked as follows. Disconnect the thermocouple lead. Press and hold the start button, then ignite the igniter. From separate source constant voltage a voltage of about 1 V is applied to the released contact of the electromagnet (from the thermocouple) relative to the housing (at a current of up to 2 A). To do this, you can use a regular battery (1.5 V), as long as it provides the necessary operating current. Now the button can be released. If the igniter does not go out, the electromagnet and draft sensor are working;

- thrust sensor

First, the force of pressing the contact to the bimetallic plate is checked (when indicated signs malfunctions, it is often insufficient). To increase the clamping force, loosen the lock nut and move the contact closer to the plate, then tighten the nut. In this case, no additional adjustments are required - the clamping force does not affect the sensor response temperature. The sensor has large stock according to the deflection angle of the plate, ensuring reliable tearing electrical circuit in case of an accident.

Unable to ignite the igniter - the flame flares up and immediately goes out.

There may be the following possible reasons similar defect:

— closed or faulty gas cock at the boiler inlet,
- the hole in the igniter nozzle is clogged, in this case it is enough to clean the nozzle hole with a soft wire;
- the igniter flame is blown out due to the strong air draft;

The gas supply is turned off during boiler operation:

- actuation of the draft sensor due to clogging of the chimney, in this case it is necessary to check and clean the chimney;
- the electromagnet is faulty, in this case the electromagnet is checked according to the above method;
- low gas pressure at the boiler inlet.

Installation and maintenance of the boiler AOGV-11.6-3

Installation and connection of the gas boiler AOGV-11.6 to communication systems

Works performed for the installation of the boiler AOGV-11.6:

Install the unit vertically and check the vertical level. Install shield 15 (Fig.1) at the bottom of the tank.

Install the draft breaker 1 (Fig. 1) on the boiler, ensuring its 11 strictly vertical position. The end of the draft breaker door 2 must not protrude outward and must deviate from the nominal position inside the draft breaker by no more than 1-2 mm.

The draw-breaker door should rotate easily on the axle. Casing 3 must not touch the bimetallic plate of the draft sensor 4.

Connect the AOGV-11.6 boiler to the chimney, gas pipeline and pipes of the heating system (CO) and hot water supply (DHW). On the gas supply pipe in front of the unit must be installed gas tap blocking gas access to the apparatus.

Connecting pipes pipelines must be precisely adjusted to the location inlet fittings apparatus. Connection should not be accompanied by mutual tension of pipes and units of the apparatus.

Fill the thermometer fitting 5 with machine or motor oil (volume of oil to be filled in 15 cm3).

Fill the heating system with water. Filling of the heating system is controlled by signal pipe 3 (Fig. 4).

After installing the AOGV-11.6 boiler, check the gas and water communications for leaks. Check the tightness of the gas pipeline connections with a soap emulsion. It is forbidden to use fire to detect gas leaks.

Install the adjusting nut 6 (Fig. 2) of the automation unit on required temperature water in the boiler.

Carry out sequential switching on of the unit.

Check that the igniter flame intensively washes the end of the thermocouple and provides instantaneous (no more than 2 seconds) ignition of the burner over the entire surface.

Check the operation of the AOGV-11.6 boiler automation by draft. Cut-off of gas to the igniter and the main burner must occur within no more than 60 seconds. and at least 10 sec. If necessary, adjust the response time of the draft sensor.

When the device is operating for heating and hot water supply, water for household needs should be supplied for a short time (the duration of one cycle of hot water intake is not more than 1.5 hours) in order to avoid violations temperature regime heating systems.

In case of long-term hot water withdrawal, we recommend: to increase the temperature and volume of hot water, first set the adjusting nut 6 (Fig. 2) to a temperature of 90 C and close the valve 10 (Fig. 4) on the main return water 7 in the heating system.

After the end of the hot water intake, open the valve 10 on the return water line 7 to restore water circulation in the heating system and set the adjusting nut 6 (Fig. 2) to the required temperature.

For the summer period, close valve 10 (Fig. 4) on return water line 7 and open valve 10 on line 12. For the autumn-winter period, close valve 10 on line 12 and open valve 10 on line 7.

Remove the shield covering the furnace window.

Press the start button 2 (Fig. 2) to the full and, holding it, bring the lit match to the igniter. The igniter should light up.

After 60 seconds (counting from the moment the flame appeared on the igniter), release the start button, while the flame on the igniter should not go out. If the flame goes out, repeat the operation no earlier than after 5 minutes.

Open the gas valve 11 (Fig. 1) of the burner, to do this, smoothly turn the valve handle 90 ° counterclockwise (the valve handle should be parallel to gas pipe).

The main burner should light up. If for some reason the burner does not ignite and the igniter goes out, re-ignite no sooner than after 5 minutes.

Install the shield in place.

Check for draft in the chimney. With normal draft, the flame of a match brought up to the door of the draft interrupter should be drawn into the draft interrupter. In the absence of draft, as well as when hot gases are knocked out of the furnace, it is impossible to use the AOGV-11.6 boiler.

By turning the adjusting nut 6 (Fig. 2) set the required water heating temperature. After heating the water to the temperature corresponding to the setting, the gas supply to the burner is automatically reduced and it switches to the “small fire” mode.

When the water temperature in the boiler unit drops (no more than 15 C), as a result of heat extraction during heating or hot water extraction, the gas supply to the burner automatically increases.

When transferring the adjusting nut from the existing temperature to a lower one, in order to exclude possible damage node "bellows-thermoballoon", it is necessary:

Close the gas valve 11 (Fig. 1) in front of the burner;

After lowering the temperature of the water in the tank to the required one, set the adjusting nut to this temperature;

Open the gas cock in front of the burner.

Close the door.

After the AOGV-11.6 boiler is put into operation until the entire heating system is completely warmed up, temporary drops of water may appear from under the bottom of the tank, falling onto the burner and the pan. This is the result of the formation of condensate (sweating) on ​​the walls of the firebox. When water is heated to 25 - 30 ° C, condensation stops.

Maintenance of the boiler AOGV-11.6

Maintenance work on the gas boiler AOGV-11.6:

Preventive inspection and repair of the boiler is carried out by specialists of the gas industry, service department factory - manufacturer, service department, having a license (permission) for this species works.

It is the responsibility of the owner to supervise the operation of the unit and to keep the unit clean and in good condition.

At the end heating season flush the heating system with an alkali solution (0.3 kg soda ash per 10 liters of water). To do this, fill the heating system with the solution and hold for 2 days, then drain the solution and flush the system with water. Fill the heating system with clean
water.

In the event of the termination of the operation of the boiler AOGV-11.6 in winter time for a long period (more than a day), completely drain the water from the heating system and the hot water supply system through the valves 10 drain lines 8 (Fig. 4) to prevent it from freezing.

Before the start of the heating season, check and clean the chimney, check for dust and debris under the unit.

To increase the service life of the unit and economical consumption gas, it is recommended to fill the heating system with a clean, chemically aggressive water with carbonate hardness not more than 2 mg. equiv/l.

During operation, once a week, check the filling of the system with water by the presence of a sufficient water level in the expansion tank. If necessary, add water to the tank.

Periodically, but at least once every six months (before the start of the heating season), check the accuracy of the thermostat settings of the AOGV-11.6 boiler automation unit. To do this, install a thermometer of any type with a measurement limit of 0 ° - 100 °С (0 ° - 160 °С) in the branch pipe for installing a thermometer 5 (Fig. 1).

Set the adjusting nut 1 (Fig.5) to 60 C.

Heat the water in the appliance tank to 60°C. The burner should switch to “small fire” mode.

If the thermometer readings deviate from the temperature set on the setting scale by more than ±5 °C, it is necessary to make adjustments.

To do this, holding the screw 4 (Fig. 5) from turning with a wrench, unscrew the nut 3 (Fig. 5) by 1 - 1.5 turns. By turning the adjusting nut 1 (Fig. 5), align the mark, the temperature of which corresponds to the reading of the thermometer with the arrow.

Then, holding the sleeve 2 (Fig.5) from turning with a wrench, slowly tighten the screw 4 (Fig.5) until the valve closes in the block. (The burner has switched to the “small fire” mode). Lock adjusting screw 4 with nut 3 (Fig.5).

Set the adjusting nut to more high temperature(burner should go to “full fire”). Remove the thermometer from the device nozzle.

At least once a year, inspect the condition of the inner surface of the coil fitting at the hot water outlet for scale.

To remove scale, pour descaler into the coil chemical removal mineral deposits "REBOUND", the manufacturer - the company "KEMILINE"; weak solution of hydrochloric acid(3 parts water to 1 part solution) or other similar means. Remove light scale with a mechanical
way. After the scale has been removed, flush the coil with a weak alkali solution, then with water.
