7.13.2 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 of the gas boiler by turning
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 Check the connection of the internal flue pipe and the
condensate collector. Make sure it is properly connected.
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. For dual pipe
connection, the indication of pipe length is based on Ø80mm.

For a dual pipe connection, all defined lengths assume a diameter of
80mm. In case of smaller or larger pipe diameters, the permissible
pipe length is respectively smaller or larger. In case of smaller
diameter, the following applies:
Ø70: 0.59×the permissible pipe length for Ø80
Ø60: 0.32×the permissible pipe length for Ø80
Ø50: 0.15×the permissible pipe length for Ø80
Contact the manufacturer to check the calculations for the resistance
of the air supply and combustion gas flue pipe and the wall
temperature at the end of the combustion gas flue pipe.
