The boiler is designed to heat water no higher than the boiling point at atmospheric pressure. It is connected to the heating system and to the hot water preparation system in accordance with its characteristics and power.

The boiler should be installed by a qualified specialist. Before installing the boiler, you need:

a) check that the boiler is configured to work with this type of gas. This information is shown on the packaging and on the factory plate (nameplate) of the boiler.

b) make sure that there is sufficient thrust in the chimney, there are no narrowing, and there is no receipt of extraneous combustion products, with the exception of cases when the chimney is specially designed to maintain several devices.

c) when joining the chimney pipe to an existing chimney, check that the chimney is completely cleaned, t.to. When the boiler was working, particles of soot can break away from the walls of the chimney and close the yield of combustion products, thereby creating a dangerous situation.

d) In addition, in order to maintain the guarantee on the device and to maintain its correct functioning, the following precautions must be applied:

DOB contour:

  • If the stiffness of the water is higher than the value of 20º F (where 1º F = 10 mg of saso3 per 1 liter of water) should be installed a polyphosphate dispenser or a similar system for softening water (magnetic, electromagnetic converter);
  • Rinse the equipment thoroughly after installing it and before starting operation;
  • For reliable operation and ease of maintenance, it is strongly recommended to install a locking valve with a filter on the input pipe of cold water supply.

one.4. The materials used in the hot water supply circuit correspond to the directive of 98/83 of the European Union.

Heating circuit

Before installing the boiler, heating equipment must be pre.cleaned to remove possible deposits or pollution, using substances available in free sale. Substances used to clean the equipment should not contain concentrated acid or alkali, which can corrode metal and damage parts of plastic and rubber equipment (for example, Sentinel X300 or X400 and Fernox Rigenerator for heating equipment). When using cleansing substances, it is necessary to strictly follow the instructions of the instructions for their use.

Operated equipment:

Before installing the boiler, heating equipment must be previously cleaned of dirt and deposits using substances available in free sale (see.point 2.one)

To protect the equipment from scale, it is necessary to use itching substances, such as Sentinel X100 and Fernox Protettivo for heating equipment. When using these substances, it is necessary to strictly follow the instructions of the instructions for their application.

We remind you that the presence of deposits in thermal equipment leads to problems in the operation of the boiler (overheating, noise of the burner, etc.P.)

With non.compliance with these recommendations, the device is removed from warranty service.

The first launch of the boiler should be made by a qualified specialist. You need to make sure the following:

a) the parameters of the boiler in power, water and gas correspond to the available systems of electro-, water, and gas supply.

How often it should turn on?

The incidence of the boiler depends on several factors:

With excessive power, the installation quickly heats up and turns off. The circulation pump provides the receipt of new portions of the cooled coolant, the temperature sensor works and starts the boiler again.

Power can be lowered by software. It is also necessary to reconfigure the boiler, in particular, increase the F11 parameter (waiting time for re.starting) to the maximum, which is 10 minutes.

The use of the thermostat allows you to significantly increase the time between the start of the unit, since the air cools and heats up much more slowly.


Do not use and/or fold easily igniting materials (solvents, paper, and t. D.) next to the boiler.

Before performing any operations, turn off the boiler power supply.

The equipment is not intended for use by people whose physical and mental abilities are limited, or by people with insufficient experience or knowledge, with the exception of cases when they are assisted from other persons responsible for their safety and instructing equipment to use equipment.

Repair of Baxi boilers (baxi) with your own hands: the main causes of breakdowns

Baxi (Baxi) is a line of gas boilers from an Italian manufacturer. The best option for maintaining a comfortable temperature in the room. The gas boilers of this company are safe, environmentally friendly, durable, almost silent, strong and economical, have high performance and are quite easy to operate, in addition, they differ in an affordable price. Even if a decrease in gas pressure is noted on the network, the boiler will not stop its work. Baxi boilers work on liquefied natural gas. Modern design allows you to organically place the boiler in the interior of any room.

In order to choose the right spare parts for the boiler after the revealed breakdown, you need to know its series and model. The most common: Baxi Luna (Comfort, Comfort Combi, Silver Space), Eco, Nula (come with a stainless steel boiler), Slim, Main.

The volume of boilers from supercompact to 80 liters. They can be installed on the floor or attached to the wall. Structurally boilers are divided into: single.circuit and double.circuit.

Operating principle

Baxi boilers are made of metal. Outside it is covered with a layer of thermal insulation.A copper heat exchanger is placed above the combustion chamber, and the burner is located under the combustion chamber.

When the air temperature changes in the room, the thermostat is automatically launched, transmitting the inclusion signal to the pump that creates a vacuum in the reverse pipeline. At the same time, the heated water begins to flow into the supply fishing line for the trimmer of the heating system under a pressure of not more than 0.45 bar (in case of pressure increased, the microprocessor gives a signal on the relay, the contacts are closed, and the burner is ignited). The work of the boiler begins with low power, which gradually increases until the temperature of the coolant reaches the given temperature. After that, the heating mode changes to the modulation mode. As soon as the temperature of the coolant deviates from the given value to the decrease, the signal comes from the thermal attempt, the intake fuel valve opens, the burner is again filled and heats with the water.

In the event that at the beginning of the boiler, the power of the boiler is too high, the burner is automatically turned off and the re.start of the system is possible only after three minutes.

When there is no need for heating, the boiler is included in the DIS mode. In this case, cold water through a three.way valve overlapping the heating fishing line for a trimmer enters the secondary circuit. From the gas valve, the fuel is put into the burner, gradually increasing power. When the water heats up, the regime of regulation of its temperature is turned on.

Possible breakdowns of Baxi boilers

Repair work in the Baxi boilers should be done with your own hands only with visible and leaky causes of breakdown. In the absence of experience in handling units or if special tools have no special tools, it is better to entrust the repairs of the boiler to the competent master.

  • – the boiler burner does not turn on or the burner of the boiler;
  • – the ignition becomes impossible;
  • – Clappes are heard in the furnace chamber;
  • – the boiler overheats;
  • – the maximum heating temperature of the coolant becomes insufficient;
  • – the work of the boiler becomes noisy;
  • – one of the sensors or elements of the system fails.
  • – moisture fell into the boiler;
  • – water (coolant) of low quality;
  • – there was a difference or decrease in gas pressure in the gas pipeline;
  • – There was a voltage difference of the mains;
  • – the heating system was mounted incorrectly.

DIY BAXI boilers repair. video

It is possible that when installing the phase and zero are connected incorrectly or the air has accumulated in the system.

The flame of the burner does not reach the maximum power

The fault of the malfunction can be incorrect pressure adjustment in the heating system, a malfunction of the gas valve modulator or breakdown of the diode bridge.

Elimination method: configure the system parameters using the boiler operation instructions.

The boiler starts and immediately stops working

The cause is low gas pressure in the gas pipeline.

Method of elimination: the value of the incoming gas pressure should reduce to five MBAR (standard. twenty.five MBAR).

Weak heating of the coolant in the heating system

Method of elimination: We check the value of the pressure on the gas valve, most likely, the Min and Max failure occurred.

Mandatory change of fees, as well as valve.

Setting a BAXi Luna 3 Boiler to Low Temperature Mode

The values ​​of temperature sensors become inaccurate

To eliminate the problem will help replace the sensor with a new.

Weak heating in the hot water supply system

The reason for this is incomplete opening a three.way valve or in its breakdown. To confirm the valve malfunction, let the system cool, block the locking valves of the heating system, then turn on the boiler in hot water supply mode. If the valve is faulty, then simultaneously with the DHW, heating will occur in the heating system.

Such noise appears due to: insufficient gas burning (minimum pressure adjustment is required); changes in the distance from the gas supply to the carrier during the inaccurate transportation of the Baxi boiler (the size of the gap should be adjusted by installing it by 4-5 mm); Excessive traction (using the damper to reduce traction in the boiler).

How to adjust the gap between the burner and the fan

Open the front panel and completely remove it from the boiler. Remove the damper from the observation hole. Behind it is a smell. To change the size of the clearance, it is necessary to unscrew the screw on which the electrode of the fabric is attached, then remove and carefully bend the electrode. Then we install it in place and close the hole in the hole.
