1. Make sure that:
- The gas valve is closed;
- The electrical connection has been properly carried out.
Make sure that, in any case, the green/yellow earthing wire
is connected to an effi cient earthing system;
- Use a screwdriver to lift the cap on the automatic air relief
valve;

button to select the standby
mode, where no hot water
or heating requests are
made.
- Start the deaeration cycle
by pressing the MODE
button for 5 seconds.
The boiler will start a
deaeration cycle lasting
about 7 minutes (See below). If you need to stop it press
the ESC button, alternatively it is possible to manually vent

and, if not, repeat the procedure.

Bleed the air from the radiators;
-
The exhaust duct for combustion products should be
suitable and free from any obstructions;

Check whether the trap contains water; if not, it must be
refi lled.
N.B.: if the boiler will not be used for long periods,
the trap should be fi lled before the boiler is started up
again. It is dangerous not to refi ll the siphon as fumes
may be released into the environment.

the meter does not detect any passage of gas. Repair any
leaks.
