Gas boiler Keber instruction manual, reviews

Pressing and washing

Crimping is not always done, due to the lack of a special pump and the reluctance to call a team, but if the heating fails in the midst of cold weather, the costs can be much higher!

It is especially important to test a new system and one that, on the contrary, has been serving for several years. The cost of crimping in construction companies from 3000 rubles

Additionally, they can charge a fee for visiting the facility (about 2 thousand rubles). By the way, a manual pressure pump will cost 4.5 - 6 thousand rubles

Peculiarities

The ATEM brand has put all its efforts into the development and production of a quality device for autonomous heating. For more than 27 years, the company has been giving heat to its consumers in the form of Zhitomir gas boilers. Since the appearance of the first boiler, a huge rebranding has been made, the device has received changes from the internal basis of spare parts to the external design. Today, the Zhytomyr boiler is a neat small block with switching instructions that even a child can handle. The main quality inherent in the boilers of this brand is the quality and reliability of the device. Product specifications have also changed as new technologies emerge. Not only these components, but also many other facts allowed the ATEM brand to get the European Quality award.

About the manufacturer

Since 2006, Keber gas boilers have been produced by the domestic company Zvezda-Strela Trading House LLC, which is part of the Tactical Missile Weapons Corporation OJSC.These heaters are well adapted to Russian operating conditions, they function smoothly even in places that are characterized by very low temperatures.

If necessary, such heaters can be used for space heating in the Far North.

The Keber range includes both household and industrial models.

Single-circuit and double-circuit units are distinguished. The former are used exclusively for heating, while others provide the room not only with heat, but also with hot water.

Technical parameters of Atem gas boilers

Atem produces:

• floor gas boilers Zhytomyr;
• wall devices ().

Units with installation on the floor are further subdivided into single-circuit and double-circuit. Devices with two circuits can heat water for two or three consumers at low costs. See the technical characteristics of all gas boilers Zhytomyr floor-standing in the aggregate.

The capacity of the hot water supply circuit of floor standing units with two lines is from 175 to 1400 l/h at a temperature difference of the heated liquid of 35 °C. The device can be equipped with a circulation pump, which is installed as a function. Parameters of the model range of double-circuit gas boilers Zhitomir of parapet type in the table.

Parapet 2-circuit units provide a flow rate of warm water from 160 to 345 l/h at a liquid temperature difference of 35 °C.

From the tables, we can conclude and make sure that the wall-mounted and floor-standing boilers of this manufacturer are adapted to the conditions of low gas pressure in the pipelines of the mains, and this is their huge plus. A weighty minus is the maximum pressure of the heat carrier in the heat exchanger, which is possibly quite low. For floor-mounted boilers, this is up to 2 kgf / m², and for mounted boilers, up to 0.7 kgf / m². While imported analogues can operate at a system pressure of up to 3 kgf / m². Therefore, you can be sure that Atem gas equipment is more suitable for gravity systems and small houses with one or two floors.

Experts do not recommend buying wall-mounted devices for 2-storey cottage buildings, since there will simply be not enough pressure for the high-quality operation of the pressure system.

Design features

The main elements of the Zhitomir boiler are:

• a building in which the main components and equipment are installed;
• gas burner block located in the furnace. Here, gas is burned and heat flow is released;
• a recuperative heat exchanger in which heat exchange takes place between the combustion products and the coolant;
• gas exhaust system, its duties include the removal of combustion products outside the boiler and discharge into the chimney.

In order to increase the efficiency of heat transfer, the gas boiler Atem Zhytomyr 3 has the following design features.

1. Heat-resistant steel heat exchanger pipes have a rectangular section, such a device allows you to increase the contact area of ​​the flue gas and the coolant.
2. The oncoming movement of heat carriers was organized, such a solution made it possible to increase the efficiency of the heat exchanger up to 92%;
3. To increase the area of ​​interaction between combustion products and coolant, as well as to prevent the accumulation of soot on the surface of the steel pipes of the ATEM boiler heat exchanger, turbulators were installed. Soot accumulates on the lower surface of the turbolizers, the walls of the pipes remain clean. To remove soot, periodically remove the turbolizers and clean them of soot.
4. Gas double-circuit turbocharged boilers in Zhytomyr around the heat exchange heating pipes have a coil of copper pipelines.

To organize a stable gas combustion process, a POLIDORO gas burner is used. Its distinguishing feature is a single-stage atmospheric type burner.The edges of the burners themselves are made of heat-resistant steel, which allows you to maintain the combustion mode with different gas supply to the furnace. Even at low gas flow rates, the edge heating is sufficient to maintain stable combustion.

The regulation of the gas supply mode is performed by the EUROSIT gas valve. This device automatically switches the gas supply to the burners depending on the temperature of the coolant. The user independently sets the temperature of the coolant, focusing on the temperature in the open air. With a decrease in the ambient temperature, the temperature of the coolant rises.

Let's move on to cleaning the column

Turn off the gas supply valve to the boiler. Using the key No. 10, we unscrew the fastening screw under the boiler door and remove the door.

Disconnect the wire connecting the piezoelectric element and the ignition electrode.

Using the key number 10, unscrew the thermocouple retainer. Using the key number 9, unscrew the thermocouple from the valve.

Note:
it is necessary to ensure that the thermocouple does not rotate during unscrewing.

We note the depth of entry of the nozzle into the main burner so as not to disturb the boiler setting.

With the key No. 17, we unscrew the nut that secures the copper tube from the burner to the valve. Using key No. 10, unscrew the ignition electrode from the pilot burner and the copper tube from the pilot burner and valve. Unscrew the two pilot burner screws with a flat head screwdriver.

The gasket installed under the pilot burner has become unusable. It will need to be replaced.

Remove the nozzle from the pilot burner.

Tip: If the nozzle is stuck, you can lightly tap the burner with a wrench.

We unscrew the four screws securing the main burner to the boiler body and the screw securing the body in order to be able to remove the main burner.

Lowering the main burner down, remove the copper tube from the valve.

Remove the main burner.

We take out the thermometer sleeve from the boiler body.

Using the key No. 10, we unscrew the four screws securing the upper cover of the boiler and remove it and the insulation sheet under it.

We unscrew the two nuts securing the flue to the boiler body.

We remove the terminals from the thrust sensor.

We remove the gas pipeline.

We remove the swirlers from the boiler heat exchanger. We clean them with a brush. If necessary, use a metal brush.

We clean the outer part of the heat exchanger with a metal brush. We clean the channels of the heat exchanger with a brush to the full depth. We clean the bottom of the heat exchanger with a brush. We also clean the gap between the boiler body and the floor. We clean the exfoliated debris with a vacuum cleaner.

With key No. 13, we release the screw that fixes the depth of entry of the nozzle into the main burner and remove it.

We clean the burner with a brush and brush, clean its holes with a vacuum cleaner. We clean the flue from dust from the outside and from the inside.

We clean the outer surface of the nozzle with a brush, then clean the nozzle holes with a needle or wire.

Note: The needle must be smaller in diameter than the diameter of the nozzle hole. Even a slight increase in the diameter of the nozzle hole can affect the combustion mode.

We install the main burner in place.

We install a copper tube with a nozzle and bait its nut onto the gas valve.

Only after that we fix the nozzle on the burner according to the mark with key No. 13.

Note:
this sequence is necessary in order not to strip the threads in the valve body.

We finally tighten the nut of the copper tube with a key number 17.

We clean the pilot burner with a metal brush.

This is how the thermocouple should be installed in the pilot burner (the tip of the thermocouple against the tongue of the flame).

Install the pilot burner on the new gasket.

Before installing the nozzle in the pilot burner, it must be slightly lapped against the tip of the copper tube for better sealing. The nozzle should also be cleaned or purged.

We connect the copper tube to the pilot burner and to the valve with a key number 10.

The remaining parts of the boiler are assembled in the reverse order.When connecting the ignition electrode, do not clamp it with a key, it is enough to do it by hand, because it is made of ceramic and can easily crack.

We make control washing of all connections. It will be possible to check the tightness of the connection of copper pipes to the main and pilot burners only when the boiler is turned on.

Rules for filling the system with water before turning on the gas boiler

Before igniting the gas boiler and turning on the heating system, it is first filled with cold coolant, which, after heating, will circulate through pipes and radiators. During the first launch, everything is carefully checked so that the work in the future is uninterrupted, and the equipment does not require repair.

These pressure parameters can be changed as they depend on the manufacturer's requirements for operating pressure in the heating system. But filling with cold water does not finally end there, since replenishment will be required after the structure is freed from air jams.

Removing air pockets before lighting a gas boiler

Before igniting a gas boiler, it is necessary to fill the heating structure with a liquid cold coolant. But one filling with water is not enough. It will either not work, or the degree of heating of the room will be insufficient. A full-fledged first start is impossible without the release of air accumulated in the system. Often in modern gas boilers there is a special system that automatically releases air when filling. But often its effectiveness is insufficient: you still need to manually reset the air locks. Only then can you start.

It is necessary to remove air plugs before turning on the gas boiler not only from the heating unit, the circulation pump, but also from all heating radiators. The process should start with batteries - for this, as mentioned above, they are equipped with Mayevsky cranes. They are opened by substituting a container from below. At first, a slight whistle will be heard, which means that air is gradually escaping from the system. After removing the plugs, water begins to flow. Then the taps are closed. A similar procedure should be done with each of the radiators. "How to choose a Danko boiler - types of heating gas boilers, features, benefits."

When the air from the batteries is removed, the pressure gauge needle should be set to a certain value. Before igniting a gas boiler, a coolant should be added to the system and thus energized. "How to turn on the Lemax boiler - operating rules."

Varieties

To date, several types are involved in the production of Zhitomir boilers - parapet (wall) and floor. In turn, floor products also have divisions into single-circuit and double-circuit.

floor standing

If a gas boiler is needed only for heating purposes, attention should be paid to single-circuit models. They are unpretentious, practical and economical.

Equipping a single-circuit boiler "Zhytomyr" primarily involves imported components. Thanks to them, the device can be turned on and off if necessary. And if there is a need, in addition to heating, to have hot water in direct access, you will need to choose from two-circuit options.

According to their technical characteristics, floor-standing boilers in most have such similarities as:

• the maximum temperature limit is +90 degrees;
• efficiency is 92%;
• gas pressure - 635 Pa.

But already when choosing a model that you definitely like, it is necessary to consider its specific characteristics and capabilities.

wall

The same separation as for floor models is also present in wall-mounted models of boilers. They can also be single-circuit and double-circuit. The efficiency of all devices is the same. The same applies to gas pressure.

But still it is worth considering their characteristics p>

• the power of parapet boilers must be at least 5 kW and not more than 20 kW;
• the coolant in the device is no more than 17.5 liters;
• depending on the chosen model, the consumption of natural gas is considered; according to the standard - 0.56–1.67 cubic meters per hour;
• profitability due to imported automation.

For its part, the manufacturer provides a wide range of boilers to choose from, but the Zhitomir-3 KS-G-020 SN model is still in great demand. This device differs from its counterparts not only in terms of availability in terms of the price factor, but also has clear technical data. The design of the device is designed in a minimalist style, outwardly the boiler looks like a cabinet. It should only be placed on the floor. On the front of the model there is a small door behind which is hidden the button for turning on and adjusting the settings of the device. In the same part there is a control window, with the help of which it is necessary to monitor the performance of the boiler.

The main package includes a housing, which also includes elements of the heat exchanger. Outside, it is covered with heat-insulating material and a casing made of steel. The burners are presented in the amount of two pieces: one is the main one, and the second is the ignition one. The package includes a gas duct and an automatic gas valve, which is responsible for safety during operation.

Turning on the boiler

1. The gas boiler is plugged into an outlet.
2. The switch must be set to zero.
3. The gas supply is turned on (the tap on the gas pipe opens).

Further actions may differ for different models of gas boilers.

For example, the Aton or Danko boiler switch must be set to the “asterisk” icon, press the entire switch and hold for 5-10 seconds.

Then, without releasing the switch, press the button located next to it.

The unit will respond with a characteristic click and hum. After that, the regulator is released and the required power is set.

To turn on the Baksi boiler, you also need to turn on the gas, plug in the plug and press the "Start" button. The operating sound will appear. The device needs to be given a little time, and it will automatically ignite the flame. After that, you need to press the power button again and by this connect the heating circuit (the corresponding icon will appear on the display). In conclusion, the desired temperature is set using the buttons.

We will consider the types of generators for gas boilers here.

To organize a full-fledged heating system in a private house, it is necessary to install a boiler. The article http://microklimat.pro/otopitelnoe-oborudovanie/kotly/kak-vybrat-dlya-chastnogo-doma.html discusses the main criteria for choosing heating equipment.

Malfunctions of gas boilers Keber

Of course, any equipment can fail. Keber boilers are no exception. Consider the most common problems that owners of such equipment have to face:

1. Unstable work .
   This problem is usually solved by cleaning the jet
   . In some situations, it is necessary to check the meter, as it may not allow gas to enter the system in the required amount.
2. The gas burner goes out a few minutes after switching on.
   There can be many reasons that lead to this, but most often this is due to the failure of the thrust sensor. The best thing to do is to contact the experts.
3. No gas supply to injectors
   .
   If you purchased a boiler with Arbat automatics, then, most likely, the stem is jammed
   in the middle of the structure. You can drop some machine oil yourself, then check the automation
   in case of a gas leak. If the above steps are not successful, then you should contact the experts.
