The Baxi Main Four 240-F is a dual-circuit heating boiler, which is the product of modernization in the fourth generation. Popular Italian manufacturer Baxi was able to produce an inexpensive, but reliable and extremely convenient unit that has excellent performance. The device is practical and compact in size.
Gas system specifications
The equipment mentioned above has a continuous electronic modulation of the flame, you can use the device to meet the needs of hot water supply and the installation of a heating system. The unit provides smooth electronic ignition. This boiler is adapted to the conditions of Russia, it is able to work stably while lowering the pressure of natural gas, which can be 5 mbar. The oxygen supply control system is patented. It is noteworthy that the burner flame dividers are made of stainless steel. The device can be reconfigured to operate on liquefied gas .
Hydraulic system specifications
The boiler of the brand Baxi Main Four 240-F includes:
- bithermic heat exchanger;
- pressure gauge;
- cold water filter;
- energy-saving pump with automatic air vent.
The manufacturer took care of the presence of a post-circulation pump, there is also an automatic bypass in the system.
Temperature control features and safety controls
When installing the boiler in the heating system, it is possible to regulate the temperature range in two modes, one of them assumes that the limit is from 35 to 80 ° C, while the other from 35 to 45 ° C. In the latter case, we are talking about the mode of warm floors. The equipment has weather-dependent automation, among other things, it is possible to connect and use an external temperature sensor. The set temperature in the heating system and hot water supply is provided automatically; the consumer can adjust these values.
The Baxi Main Four 240-F boiler provides a digital temperature indication. Additionally, the user has the ability to connect a room thermostat and a timer. You can control the operation of the device through a liquid crystal display, this interactive control is via buttons. The device has electronic protection against scale, and in case of emergency, a signal occurs that is sent to the dispatcher's console. You can control the intensity of the flame, as well as use the pump blocking protection system, it turns on automatically every 24 hours.
You can not be afraid that the water in the heat exchanger will overheat, for this there is a protective thermostat. When removing combustion products, a draft sensor works, it controls that this process takes place safely. Baxi Main Four 240-F has a special system that controls the pressure of the water, with a lack of this value, the pressure switch is activated. 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 specific type of gas. The chimney must have sufficient draft; there should be no restriction in it. When the flue pipe is connected to an existing chimney, you should check that the chimney is clean, because when the device is working, the soot elements come off the walls and block it, creating a dangerous situation. If the water hardness exceeds 20º F, then 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 supply must comply with the directives of the European Union. After the equipment should be washed well, this also applies to the stage of the start of operation.
Operating Instructions for Long Shutdown
The Baxi gas boiler may not be used for a long time, and frost protection must be provided. Frequent drains of water from the heating system should be excluded, as this will cause harmful scale deposits inside the heat exchangers and the boiler. If the unit will not be used in the winter, then antifreeze can be added to the heating system. The instructions should indicate that it is intended for these purposes. If we are talking about a double-circuit option, then the antifreeze should be made on the basis of propylene glycol.
When a Baxi gas boiler is used in winter, and antifreeze is present in the heating system, its concentration should correspond to a freezing temperature in the range from -15 to -20 ° .
As you know, the equipment has a frost protection function, however, it only works if the temperature of the water in the supply is less than 5 ° C. But the burner will work until it reaches a temperature of 30 ° C at the feed. The functionality will work if the boiler is connected to power, 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 often choose a boiler brand Baxi Main Four 240-F. Pressure drops - this is precisely the problem that most often occurs when this equipment is operating. If this happens, then turn off the heating system, the equipment is disconnected from the water supply system, and then the water is drained. The tank is pumped up using a car pump with a pressure gauge to control the pressure. You need to pump until the water stops flowing. As soon as the coolant flows out, it is necessary to continue pumping to a pressure level of 1 bar. Then the boiler is again connected to the communications, and the pressure is brought to a value of 1.5 bar. Then you can restart the heating.
The 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 again, and the indicators should level out. Normal pressure will be achieved, although experts do not consider such fluctuations to be the norm, but they will not be harmful to heating equipment.
