Gas equipment is ubiquitous in apartments and country houses. You independently adjust the technique by setting a comfortable room temperature. So you are not dependent on utilities, you can save fuel on your own. But for the operation to be truly economical, the correct setting of the gas boiler is important.
How to set up a boiler yourself
Why do you need the correct adjustment of technology:
- To save resources.
- To make the room comfortable, use hot water.
- To extend equipment life.
You need to start with the correct choice of the boiler, its power. Consider the features of the room: the number and area of windows, doors, insulation quality, wall materials. The minimum calculation is carried out from heat loss per unit time. You will learn more about this in the article “How to calculate the power of a gas boiler”.
Gas boilers are divided into single-circuit and double-circuit. The latter perform heating on the heating circuit and hot water supply (DHW). Single-circuit units provide only heating. Therefore, to obtain hot water, indirect heating boilers are installed.
According to the type of placement, the technique is floor and wall. Units placed on the floor have great power. Therefore, they are used for large areas (from 300 m²). Installation is carried out only in separate rooms (boiler rooms). These are models Baxi ("Baxi"), Buderus ("Buderus"), "Navien", "Kiturami".
Attachments (Neva Lux, Arderia, Daewoo, Ariston, Bosch) fit perfectly in small apartments in the kitchen. Therefore, it is important to consider all the nuances of the location. The comfort of those living, as well as the durability of the boiler, depend on the correct selection of parameters.
Power setting
The strength of the heating depends on the modulation of the gas burner. If you have chosen an electronically controlled device, then it includes a thermostat, which is connected to a room thermometer. The adjustment is automatic: the thermometer measures the temperature in the room. As soon as it falls below comfortable, he gives a command to start the burner or increase the flame force.
In normal mode, the thermometer monitors the temperature in only one room. But if you install valves in front of each radiator, control will be in all rooms.
You can adjust the burner manually by acting on the gas valve. This is true for atmospheric boilers with an open combustion chamber. So, in Protherm Cheetah, Proterm Bear models, the valve is regulated by an electric motor. To change the settings, you need to go to the service menu. Most often this is done by a specialist, and the user performs the actions specified in the instructions.
But still we will tell you how to call up the hidden menu for adjustment.
Before entering the menu and making settings, do this:
- Unscrew the taps on the batteries.
- Set the maximum value on the room thermostat.
- In the user settings, set the maximum temperature that you use in severe frosts. The burner always shuts off when the readings reach 5 ° C more than set. For example, at +75 degrees, the shutdown will happen after reaching 80 degrees.
- Cool the coolant to 30 ° C.
For Protherm Gepard:
- Hold down the Mode key on the panel. As soon as “0” appears on the display, set the value to 35 by pressing “+” and “-”.
- Press Mode to confirm.
- As soon as d lights up on the screen. 0, enter the line number in the menu. Do this with the “+” and “-” d. (Number). To set the maximum power of the burner, select d.53, the minimum - d.52.
- Use Mode to move to parameter selection. Change it to “+” “-”.
- The installation receives an automatic confirmation.
- Return to the original menu - hold Mode.
During regulation using the panel, monitor flame changes and temperature increases.
For Proterm Panther actions differ:
- Press Mode for about 7 seconds.
- Using the 2 keys (see the picture above), enter code 35.
- Confirm your entry.
- As soon as d.00 appears on the left side of the screen, use the 2 buttons to enter the number.
- You can change the parameter on the right side of the screen using the 3 keys.
- After confirmation, press mode to exit the menu.
For models "Electrolux Quantum":
- Unplug the device for a few seconds.
- After turning on, hold the red button on the controller for 15 seconds.
- As soon as P01 lights up on the display, press the red key until P07 appears.
- If after P07 the number 1 flashes, then 38 ° C – 85 ° C is maintained. If 4 - 60 ° С – 85 ° С, 7 - 38 ° С – 60 ° С glows.
- Use the “+” “-” knob to adjust the desired value.
- Turn off the boiler for a few seconds. Now it will automatically support the specified parameters.
How to program technique Viessmann (Wiesman)look at the video:
For Eurosit 630:
All the above steps are used to configure the device in heating mode. Many users are faced with a problem when unstable temperature water flows from the tap in hot water mode. To fix this, use our recommendations.
Changes in hot water temperature
To adjust the water supply to a comfortable level, it is necessary to reduce the power of the burner.
- Open the mixer to switch the boiler to hot water mode.
- Set the temperature to 55 ° C.
- Go to the service menu as described above (for “Proterm”).
- Select option d. 53.
- Press Mode.
- After that, the line will show the maximum power. For example, take the indicator 17.
If you experiment and choose immediately the minimum value - 90, then the temperature of the tap water will not be comfortable. We set 80 and get an increase in the degree of water. Increase the values gradually until you are satisfied with the DHW supply. In our case, the water reached +50 degrees, and the setting was 80. This despite the fact that the factory was 17. This is the difference.
SIT valve adjustment
The automation of some units provides for a gas valve type SIT. It is found in Vaillant (Vailant) and Proterm models. The adjustment is made by rotating the bolts on the valve. To change the power, you need to change the pressure. Values of 1.3–2.5 kPa are considered normal.
Valve bypass
If the batteries in the room do not warm up evenly, increase the circulation rate of the coolant. To do this, turn the bypass screw clockwise.
If, when the heating is switched on, the batteries on the contrary are noisy, then reduce the coolant speed by turning the screw in the opposite direction. Use a pressure gauge or a digital differential pressure gauge to configure and measure. It will indicate the nominal pressure, which should not exceed 0.2–0.4 bar.
Startup problems
During the launch and operation of the gas equipment Bosch, Ariston, Ferroli, Oasis, problems may arise.
Boiler timing
With the wrong choice of equipment power, excessive cycling occurs. This means that the burner of the device often turns on and off, and the radiators do not have time to warm up. Firstly, this leads to a rapid deterioration of components and equipment parts. Secondly, a large amount of fuel is used.
To eliminate the phenomenon and reduce cyclicity, two methods are used:
- Reduce burner flame.
- They increase the heating power, including additional radiators in the circuit.
How to fulfill the first paragraph, we described above. Sometimes you have to mount additional batteries, although this is quite a costly method.
The igniter does not work
If ignition attempts at Immergaz, Korea Star are unsuccessful, inspect the ignitor. He could be clogged. The problem is resolved by cleaning the part. You can wipe it with a dry cloth or use a solvent.
Inspect the combustion unit. Often soot accumulates there. By lightly tapping the gas supply pipe to the burner, soot is removed.
The igniter has worked, but there is still no ignition. Diagnostics required:
- thermocouples;
- supply valve;
- temperature regulator;
- solenoid valve.
No DHW heating
When the mixer is opened, water is supplied with a small pressure, the flow is cold. Inspect the heat exchanger for obstruction due to scale deposits. Clean the tubes with reagents. Use a pump for bleeding. After the procedure, rinse the unit with running water. For comfortable temperature readings, install cleaning filters. They reduce the likelihood of scale formation.
You can find recommendations from the manufacturer in the instructions. Correct connection and adjustment of equipment is the key to its effective and long-term operation.
