to a collective flue or to a single flue with
natural draft, the flue or chimney must be expressly designed by professionally qualified technical
personnel in conformity with current regulations and be suitable for sealed chamber units equip-
ped with fan.
ONLY FOR THE ITALIAN MARKET
According to Art. 5 Para. 2,. f) and g) of Min. Decree 37/08, gas systems, chimneys, flues
and smoke systems with a capacity of over 50 kW and in any case all multiple flues instal-
led in Italy must be designed by a Professional registered in the appropriate professional

.
Backflow preventer valve
The boiler
BLUEHELIX MAXIMA
is equipped as standard with a backflow preventer valve (anti-
backflow system), therefore it can be connected
to a positive
pressure collective flue system, only
if using G20 gas.
In case of C10-type boiler installation, apply the relevant white adhesive plate (included in
the document bag supplied with the unit) in a CLEARLY VISIBLE PLACE on the FRONT PA-
NEL.
After installation, check the tightness of the fumes and gas circuit.
OTHERWISE THERE IS DANGER OF SUFFOCATION DUE TO THE EMISSION OF COMBU-
STION FUMES.
