Description of the double-circuit gas boiler BAXI MAIN Four 24

Model BAXI MAIN Four 24 is a wall-mounted, chimney, double-circuit boiler with gas supply and a bithermic heat exchanger. The MAIN Four series introduced by BAXI is the fourth generation of gas heating devices. This line is a continuation of the MAIN Digit line, popular in the expanses of the post-Soviet space.

The BAXI MAIN Four 24 boiler is small in size, which makes it affordable to install in small rooms. The control is carried out using the LCD display and buttons, all manipulations with the setting are quick and easy. Distinctive features models from other devices of this line are in the following factors:

  • The presence of a liquid crystal display.
  • Highly small size- 73x40x30 cm.
  • Possibility to connect an outdoor temperature sensor, a room thermostat, a timer with programming settings.
  • Digital control system.
  • Bithermic heat exchanger.
  • Circulation pump.

Instructions for a double-circuit gas boiler BAXI MAIN Four 24

Before installing the boiler, make sure that it is designed to work with the type of gas that is supplied to the house. Information about this is available on the original packaging of the boiler. Next, the chimney is checked, it should not have constrictions and various combustion products. The only exceptions are those structures that are designed to serve several devices at once.

  • For water hardness values ​​above 2000F, where 100F = 10mg CaCO3 per liter of water, installation is carried out using a polyphosphate dispenser or any other suitable water filtration system.
  • The equipment between installation and the start of operation is thoroughly washed from possible contamination by sheathing elements and other materials. To do this, use special substances for washing this type of equipment. Washing fluids do not contain concentrated acids or alkalis, which have a detrimental effect on metal and plastic elements of the boiler.
  • For the hot water circuit, materials are selected that comply with Directive 98/83 EC.

Before the first start-up of the installed boiler, it checks whether all its systems are connected correctly, whether the parameters of gas and water correspond to the parameters of the equipment. The start is as follows:

  • The boiler is connected to a power source.
  • Gas is given by opening a tap.
  • Press the power button and set the desired mode - summer, winter or only heating.
  • Set the desired temperature and DHW using the +/- buttons.
  • When the machine is turned on, the symbol in the form of a tongue of flame lights up on the display. In summer mode, another symbol is lit.

During the first start in gas pipes air often accumulates, forming a cork. In such a situation, the burner does not ignite, and the boiler is blocked. To start the machine, it is necessary to repeat the switching on and off process so that the gas enters the burner. At the same time, press the "reset" button.

To shut down the equipment completely, the power supply must be disconnected. When the switch is turned to the "off" position, the appliance does not work, but the circuit is energized and the frost protection function is on.

It is not recommended to frequently drain the water from the heating system, as the constant replacement of the fluid leads to the formation of scale and deposits. If the equipment is not used in winter period, it is protected from freezing with the help of special antifreeze liquids, which are designed specifically for heating appliances. For the BAXI MAIN Four 24 model, it is recommended to use propylene glycol-based fluids for temperatures from -15 to -2000C. Also, the model is equipped with a frost protection system that turns on the burner if the water temperature drops below 500C. This function works if the boiler is connected to a power source, there is gas in the network, the pressure reaches the required values, the boiler is not in a blocked state.
