If the boiler is to be connected
BLUEHELIX TECH RRT 24 C
to a collective flue or to a single flue with natural draught,
the flue or chimney must be expressly designed by professionally qualified technical personnel in conformity with the
current regulations and be suitable for room sealed fan assisted boilers.
Backflow preventer valve
The boiler

is equipped as standard with a backflow preventer valve (anti-backflow sys-
tem), therefore it can be connected
to a positive
pressure collective flue system, only if using G20 gas.
