2 Remove the O-ring from the concentric pipe and fit it around the
flange of the concentric adapter Ø80/125.
3 Place the concentric adapter in the top of the appliance and
turn it clockwise so that the measurement nipple points straight
forward.
4 Fit the concentric pipe for the air supply and combustion gas
flue into the adapter. The integral sealing ring ensures an
airtight connection.
5 Check the connection of the internal flue pipe and the
condensate collector. Make sure it is properly connected.

To change the 60/100 concentric
connection to a dual pipe connection
The concentric connection can be changed from Ø60/100 to a dual
pipe connection 2× Ø80 by an adapter set.

counterclockwise.
2 Remove the O-ring from the concentric pipe and fit it around the
flange of the dual pipe adapter Ø80.
3 Place the combustion gas connection (Ø80) in the top of the
appliance and turn it clockwise so that the measurement nipple
points straight forward. The integral sealing ring ensures an
airtight connection.
4 Remove the lid from the air supply connection. Make sure to
properly connect the air intake. Room air dependent installation
is NOT allowed.
5 Fit the pipes for the air supply and flue gas thoughtfully in the
air inlet opening and flue gas adapter of the unit. The built-in
gaskets ensure there is an air tight seal. Make sure that the
connections are not mixed.
6 Check the connection of the internal flue pipe and the
condensate collector. Make sure it is properly connected.

INFORMATION
Carefully follow the instructions as described in the adapter
set.
7.13.3
Calculate the total piping length
When the resistance of the flue pipe and air supply pipe increase,
the appliance power will decrease. The maximum permitted
reduction in power is 5%.
The resistance of the air supply pipe and combustion gas flue
depends on:
▪ the length,
▪ the diameter,
▪ all components (bends, elbows,...).
The total permitted pipe length of the air supply and the combustion
gas flue is indicated for each appliance category.
