If the BlueHelix HiTech RRT C boiler is to be connected to a flue or a single chimney with natural
draft, the flue or chimney must be expressly designed by professionally qualified technical person-
nel in conformity with the current regulations and be suitable for sealed chamber units equipped
with fan.
Backflow preventer valve
The BlueHelix HiTech RRT C boiler is fitted as standard with a clapet non-return valve (backflow
preventer) therefore it can be connected, only if running on G20 gas, to collective flues in posi-
tive pressure.
Using this type of installation, parameter P67 must be set to 1.
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
PANEL.
