7.12 Connecting the boiler to the flue gas system
WARNING
▪
Make sure that the socket connections of the flue and air supply duct materials
are correctly sealed. Improper fastening of the flue and air supply duct can lead
to hazardous situations or result in personal injury.
▪
Check all flue components for tightness.
▪
Do NOT use screws or parkers to mount the flue system as leakage can occur.
▪
Sealing rubbers can be negatively affected when grease is applied, use water
instead.
▪
Do NOT mix any components, materials or ways of coupling from different
manufacturers.
The gas boiler is designed ONLY for operation independent of room air.
The gas boiler is delivered with a 60/100 concentric flue gas/air intake connection.
Fit the concentric pipe carefully in the adapter. The built-in gaskets ensure there is
an air tight seal.
An adapter piece 80/125 concentric connection is also available. Fit the concentric
pipe carefully in the adapter. The built-in gaskets ensure there is an air tight seal.
INFORMATION
Carefully follow the instructions as described in the adapter set.
The concentric adapter piece is equipped with a measuring point for the gas
exhaust and one for the air intake.

The air supply and the flue pipe can also be connected separately as a dual pipe
connection. An option to change the gas boiler from a concentric to a dual pipe
connection is available.
NOTICE
When installing the gas exhaust take the installation of the outdoor unit into
account. Make sure the exhaust gases are not sucked into the evaporator.
When installing the gas exhaust and the air intake, take into account the
serviceability of the indoor unit. When the gas exhaust/air intake goes backwards
over the indoor unit, the expansion vessel cannot be accessed and, if necessary, will
have to be replaced outside the unit.
7.12.1 To change the gas boiler to 80/125 concentric connection
The concentric connection can be changed from Ø60/100 to Ø80/125 by an
adapter set.
