Items 21, 22 and 23 are displayed alternatively with the gas energy consumption value expressed in millions, thousands and units
of kWh. e.g.: 21 / 033 / 145 / 827 corresponds to a gas energy consumption in HEATING of 33.145.827 kWh.
6. FILLING THE SYSTEM
Periodically check that the pressure displayed on the pressure gauge is 1 - 1.5 bar, with the system cold. If it is lower, turn the
system lling tap installed by the installer. Open the tap very slowly in order to vent the air.
The boiler is tted with a hydraulic pressure gauge which prevents the boiler from working if there is no water.
If pressure drops occur frequently, have the boiler checked by the AUTHORISED TECHNICAL SERVICE CENTRE.
7. ROUTINE MAINTENANCE INSTRUCTIONS
To keep the boiler efcient and safe, have it checked by the Authorised Service Centre at the end of every operating period.
Careful servicing ensures economical operation of the system.
8. SWITCHING OFF THE BOILER
To turn off the boiler, disconnect the electric power supply using the two-pole switch. In the “Off” operating mode the boiler stays
off but the electrical circuits remain powered and the anti-freeze function remains active.
