Flue pipe and air supply
•
The boiler is equiped with an adapter suitable to be connected to a concentric
flue system with the dimensions 60/100
•
The flue systems needs to be correctly connected into the adapter . The internal
seals in the adapter assure the tightness of the system.
•
By replacing the concentric adapter 60/100 by a 80/125 version the boiler can be
connected to concentric flue system with the dimensions 80/125.
•
By replacing the concentric adapter 60/100 by a single pipe 80 mm adapter and
removing the plastic cap from the air inlet connetion the boiler can be connected
to a twin pipe 80/80 flue system.

Open appliance connection
IMPORTANT
Make sure the boiler room complies to the regulatory
requirements for connecting to a flue system in accordance to
B23 or B33.
When connection the boiler to a flue system in accordance to
B23 or B33 the electrical protection class is IP20
1.
Fit the pipe for the combustion gas flue into the flue outlet. The integral sealing
ring ensures an airtight connection.

Closed appliance connections
Two-pipe connection
1.
Fit the pipes for the air supply and combustion gas flue into the appliance inlet
and outlet. The integral sealing rings ensure an airtight connection.
Concentric connection
With the concentric adapter set the standard two-pipe connection can be changed to
a concentric connection (80/125 or 60/100).
1.
Fit the concentric pipe for the air supply and combustion gas flue into the
