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.
9.4.1 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.
1 Remove the concentric pipe from the air supply and combustion
gas pipe at the top
counterclockwise.
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.

9.4.2 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.
1 Remove the concentric pipe from the air supply and combustion
gas pipe at the top
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 carefully 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.
