Checks on parts and components
Gas supply
The pressure must be stable at the setting made during installation. It must not be noisy.
Filters
Check and clean the line filters or replace them if necessary.
Fan
Make sure no dust has accumulated inside the fan and on the blades: dust reduces the air flow.

impurities coming from the room, and correctly positioned.

once a year.

• check and cleaning the internal parts of the burner and boiler as indicated in the following sections;
• complete combustion analysis (after at least 10 minutes' operation) and check of correct settings;

burner by means of the main system switch. Also turn off the fuel supply.
