The A2 F is designed for
ambient air-independent
operation. It is
fitted as standard with a concentric flue gas /air supply pipe DN
80/125.
INFORMATION
In some cases, the resonance in the flue gas system can
amplify the noise at the mouth of the flue gas duct. The
noise level can be effectively reduced by using a silencer
(accessory:
DN 80: E8
MSD
or
DN 110:
E11 MSD
).
