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

Before installing the boiler, you should make sure that it is designed to work with the type of gas supplied to the house. Information about this is available on the boiler’s original packaging. Next, the chimney is checked to ensure there are no narrowings or various combustion products in it. The only exceptions are those structures that are designed to serve several devices at once.

• For water hardness values ​​above 2000F, where 100F = 10 mg CaCO3 per liter of water, installation is carried out using a polyphosphate dispenser or any other suitable water filtration system.
• Between installation and start of operation, the equipment is thoroughly washed to remove possible contamination from casing elements and other materials. To do this, use special substances for washing this type of equipment. Flushing liquids do not contain concentrated acids or alkalis, which have a detrimental effect on the metal and plastic elements of the boiler.
• For the hot water supply 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 and whether the gas and water parameters correspond to the equipment parameters. Starting is done as follows:

• The boiler is connected to an electrical power source.
• Gas is supplied by opening the tap.
• Press the power button and set the desired mode - summer, winter or heating only.
• Install desired value temperature and DHW using the +/- buttons.
• When the device is turned on, the flame symbol lights up on the display. In summer mode, a different symbol lights up.

During the first launch in gas pipes Air often accumulates, forming a plug. In such a situation, the burner does not ignite and the boiler is blocked. To start the machine, you must repeat the process of turning it on and off so that the gas enters the burner. At the same time, press the “reset” button.

To completely shut down the equipment, you must disconnect the electrical power source. When the switch is turned to the off position, the appliance does not operate, 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, since 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 intended specifically for heating devices. For the BAXI MAIN Four 24 model, it is recommended to use propylene glycol-based fluids for temperatures from -15 to -2000C. The model is also equipped with an anti-freeze system, which 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, and the boiler is not in a blocked state.
