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.
7.6.1 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 of the gas boiler by turning 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.
