4. Bleed the air from the radiators.
5. Check the pressure gauge reading to verify that there is
suffi cient plant pressure (1-1.5 mbar); if not, the display will
signal the need for re-establishing the pressure.
Re-establish the pressure by opening the water inlet valve
located underneath the boiler.
6. The exhaust duct for combustion products should be suitable
and free from any obstructions;
7. Any necessary ventilation inlets in the room should be open
(type B installation).

refi lled.
N.B.: if the boiler will not be used for long periods, the
siphon 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 boiler connection seals, making sure that the meter does
not detect any passage of gas. Eliminate any leaks.
