Gas boiler Baxi Main Four 240-F: instruction, specifications

Baxi Main Four 240-F is a two-circuit heating boiler, which is a product of modernization in the fourth generation. The popular Italian manufacturer Baxi was able to produce an inexpensive but reliable and extremely convenient unit that has excellent performance characteristics. The device is practical and has compact dimensions.

Characteristics of the gas system

The equipment mentioned above has a continuous electronic flame modulation, the device can be used to provide the needs of hot water supply and the arrangement of a heating system. The unit provides a smooth electronic ignition. This boiler is adapted to the conditions of Russia, it is able to work steadily with a decrease in the pressure of natural gas, which can reach 5 mbar. The oxygen control system is patented. It is noteworthy that the flame splitters of the burner are made of stainless steel. For operation on LPG, the device can be reconfigured.

Hydraulic system characteristics

Boiler brand Baxi Main Four 240-F has the following components:

• Bithermic heat exchanger;
• Manometer;
• Filter for cold water;
• Energy saving pump with automatic air vent.

The manufacturer has taken care of the presence of the postcirculation pump, there is an automatic bypass in the system.

Characteristics of temperature control and safety monitoring devices

In the heating system, when installing the boiler, it is possible to adjust the temperature range in two modes, one of which assumes a limit of 35 to 80 ° C, while the other from 35 to 45 ° C. In the latter case, we are talking about the regime of warm floors. The equipment has weather-compensated automation, among other things, it is possible to connect and use an external temperature sensor. The set temperature in the heating system and DHW is automatically provided, the user can adjust these values.

The Baxi Main Four 240-F boiler provides a digital temperature display. In addition, the user can connect a room thermostat and a timer. The device can be monitored through a liquid crystal display, this interactive control is controlled via buttons. The device is electronically protected against scale, and in the event of an emergency, a signal is generated that is sent to the controller's console. You can control the intensity of the flame, and also use the system to protect against blocking the pump, every 24 hours it turns on automatically.

You can not be afraid that the water in the heat exchanger overheats, for this there is a safety thermostat. When removing combustion products, the traction sensor works, and it controls that the process takes place safely. Baxi Main Four 240-F has a special system that controls the water pressure, if this value is insufficient, the pressure switch is triggered. You can not be afraid that the system will freeze, for this there is a special protection.

Installation Instructions

The Baxi Main Four 240-F boiler must be prepared before installation. To do this, make sure that the equipment is configured to work with a certain type of gas. The chimney must have sufficient traction, there should not be constrictions in it. When connecting the smoke exhaust pipe to the existing chimney, check that the chimney is clean, because when the unit is operating, the soot elements come off the walls and block it, creating a dangerous situation. If the water hardness exceeds 20 ° F, a polyphosphate dispenser or any other similar system should be used to bring the water in a state that complies with current regulations. The materials used in the hot water circuit must comply with the directives of the European Union. The equipment after it should be well washed, this also concerns the stage of the start of operation.

Instruction manual for long-term shutdown

The Baxi gas boiler may not be used for a long time, and frost protection must be provided. It is necessary to exclude frequent drains of water from the heating system, as this causes harmful deposits of scale inside the heat exchangers and the boiler. If the unit is not to be used in winter, then it is possible to add antifreeze to the heating system. The instruction should indicate that it is intended for these purposes. If it is a two-circuit variant, the antifreeze should be made on the basis of propylene glycol.

When the Baxi gas boiler is used in winter, and the antifreeze is present in the heating system, its concentration should correspond to the freezing point in the range of -15 to -20 ° C.

As is known, the equipment has a function of frost protection, but it only works if the water temperature at the supply is less than 5 ° C. But the burner will work until reaching a temperature of 30 ° C on the feed. The functional will operate if the boiler is connected to the power supply, there is gas in the network, the equipment is not blocked, and the pressure in the system corresponds to the parameters.

Cost and some malfunctions

Recently, consumers quite often choose a boiler of the brand Baxi Main Four 240-F. Pressure is falling - this is the problem that most often occurs when this equipment is operating. If this happens, the heating system must be switched off, the equipment is disconnected from the water supply system, and then the water is drained. The tank is pumped using an automobile pump with a pressure gauge to monitor the pressure. You need to pump until the water stops flowing. As soon as the coolant flows out, it is necessary to continue to pump to a pressure level of 1 bar. Then the boiler is connected again to the communications, and the pressure is brought to a value of 1.5 bar. Then you can start the heating again.

Baxi Main Four 240-F, whose price is 35,000 rubles, sometimes faces the problem of reducing pressure, when the temperature of the coolant is at a critical level. After that, the device should start up again, and the indicators should be leveled. Normal pressure will be achieved, although experts do not consider such fluctuations the norm, but they will not be harmful for heating equipment.
