Gas equipment is ubiquitous in apartments and country houses. You independently regulate the equipment, setting a comfortable temperature in the room. So you are not dependent on utilities, you can save fuel as you see fit. But for the operation to be really economical, the correct setting of the gas boiler is important.
How to set up a boiler with your own hands
Why do you need the correct adjustment of equipment:
- To save resources.
- To make it comfortable to be in the room, use hot water.
- To extend the life of the equipment.
You need to start with the right choice of the boiler, its power. Consider the features of the room: the number and area of windows, doors, the quality of insulation, wall materials. The minimum calculation is based on heat losses per unit of 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 to 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 equipment is floor and wall. Placed on the floor, the units have more 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 (“Baksi”), Buderus (“Buderus”), “Navien”, “Kiturami”.
Attachments (Neva Lux, Arderia, Daewoo, Ariston, Bosch) fit perfectly in small apartments in the kitchen. Therefore, it is important to take into account all the nuances of the location. The comfort of residents, as well as the durability of the boiler, depend on the correct selection of parameters.
Power setting
The heating power depends on the modulation of the gas burner. If you have chosen an electronically controlled device, then it includes a thermostat that is connected to a room thermometer. Adjustment occurs automatically: 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 strength of the flame.
In normal mode, the thermometer controls the temperature in only one room. But if you install valves in front of each radiator, control will be in all rooms.
It is possible to adjust the burner manually by acting on the gas valve. This is true for atmospheric boilers with an open combustion chamber. So, in the Protherm “Gepard”, “Proterm Bear” models, the valve is controlled 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 indicated in the instructions.
But still, we will tell you how to call the hidden menu for adjustment.
Before entering the menu and setting up, do this:
- Open the taps on the batteries.
- Set the room thermostat to the highest setting.
- In the user settings, set the maximum temperature that you use in severe frosts. The burner always turns off when the reading reaches 5°C above the set value. For example, at +75 degrees, a shutdown will occur when it reaches 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. 0, enter the line number in the menu. Do this with “+” and “-” d.(number). To set the maximum burner power, select d.53, the minimum – d.52.
- Use Mode to navigate to parameter selection. Change it “+” “-“.
- The installation receives an automatic confirmation.
- Return to the original menu – hold Mode.
During regulation, use the panel to monitor the change in flame and temperature rise.
For “Proterm Panther” actions are different:
- Press Mode for about 7 seconds.
- Using keys 2 (look at 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 Electrolux Quantum models:
- Unplug the appliance from the mains for a few seconds.
- After turning on the regulator, hold the red button for 15 seconds.
- As soon as P01 lights up on the display, press the red key until P07 appears.
- If the number 07 flashes after P1, then 38°C – 85°C is maintained. If it glows 4 – 60°С–85°С, 7 – 38°С–60°С.
- Use the “+” “-” knob to adjust the desired value.
- Switch off the boiler for a few seconds. Now it will automatically support the specified parameters.
How to program technology Viessmann (“Vissman”), look at the video:
For Euros 630:
All the steps above are used to set the appliance in heating mode. Many users are faced with a problem when, in DHW mode, water of an unstable temperature comes out of the tap. To fix this, use our recommendations.
Hot water temperature changes
To regulate the water supply to comfortable levels, it is necessary to reduce the burner power.
- Open the mixer to switch the boiler to DHW mode.
- Set the temperature to 55°C.
- Go to the service menu as described above (for “Proterm”).
- Select parameter d.53.
- Click Mode.
- After that, the maximum power will appear in the line. Let’s take 17 as an example.
If you experiment and immediately select the minimum value – 90, then the temperature of the water from the tap will not be comfortable. We set 80 and we get an increase in the degree of water. Raise the values little by little until you are satisfied with the DHW supply. In our case, the water reached +50 degrees, and the setting was 80. This is despite the fact that the factory was – 17. That’s the difference.
SIT valve adjustment
The automation of some units provides for the presence of a gas valve of the SIT type. It is found in the models Vaillant (“Vailant”) and “Proterm”. Adjustment is carried out by turning 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.
To reduce pressure, turn the bolts counterclockwise. To reduce the pressure in DHW mode, you need to rotate the adjustment nut. More details are shown in the video:
Bypass valve
If the batteries in the room warm up unevenly, increase the coolant circulation rate. To do this, turn the bypass screw clockwise.
If, on the contrary, the liquid makes noise in the batteries when the heating is turned on, then reduce the coolant speed by turning the screw in the opposite direction. Use a pressure gauge or a digital differential pressure gauge to set up and measure. He will indicate the nominal pressure, which should not exceed 0,2–0,4 bar.
Startup problems
During the launch and operation of Bosch, Ariston, Ferroli, Oasis gas equipment, problems may arise.
Boiler clocking
With the wrong choice of equipment power, excessive cyclicity 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, it leads to rapid wear of units and parts of equipment. Secondly, a large amount of fuel is used.
To eliminate the phenomenon and reduce the cyclicity, two methods are used:
- Lower the burner flame.
- Increase the heating power by including additional radiators in the circuit.
How to complete the first paragraph, we described above. Sometimes you have to mount additional batteries, although this is a rather expensive method.
Igniter not working
If ignition attempts at Immergaz, Korea Star were unsuccessful, inspect the igniter. He could get dirty. The problem is fixed by cleaning the part. You can wipe it with a dry cloth or use a solvent.
Examine the combustion block. Soot often accumulates there. Soot is removed by lightly tapping on the gas supply pipe to the burner.
The igniter worked, but there is still no ignition. Diagnosis required:
- thermocouples;
- supply valve;
- thermostat;
- 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 clogging caused by scale deposits. Clean the tubes with reagents. Use a pump to pump. After the procedure, rinse the knot with running water. To make the temperature readings comfortable, install cleaning filters. They reduce the likelihood of scale formation.
You can find recommendations from the manufacturer in the instructions. Proper connection and adjustment of equipment is the key to its efficient and long-term operation.
