Before starting any wall-hung boiler, check whether the pointer of the water pressure gauge is at 1- 1. Between five bars.

Heating: If the water pressure is within the above range, open the gas pipe valve, turn on the power of the machine, set the machine in the winter position, and set the heating temperature. Usually, the upper limit temperature of floor heating can be set at 55-60 degrees Celsius, and the highest heating temperature of radiator can be set at 75-85 degrees Celsius (if the radiator has no scald protection, it is better to set the temperature lower). It doesn't matter after normal ignition.

Bathing: After the pressure of the water pressure gauge is normal, open the gas valve of the gas pipe, turn on the machine, set the machine in the summer position-only the position of the shower head icon (if it is winter, set it in the winter position-the position where the heating icon and the shower head are together), set the hot water temperature at 42-45 degrees Celsius, turn on the hot water head, and take a shower after the water temperature is suitable and stable.

Anti-freezing: If the water pressure gauge is normal, just plug in the machine power supply (no need to start) and open the air circuit (there must be an air source).

The above operation is applicable to common brands of wall-hung boilers in the market, such as Squirrel, ariston, Bosch and Beretta. Your wall-hung boiler should also be in this category!
