7.1 Parallel boiler connection
The boiler comes as standard with a parallel connection for the flue gas outlet and air
supply system.
The air supply opening (1) has a diameter of ø100mm.
The air supply channel can be connected to it, or, if it involves an “open device” (Drainage
category B), an air filter can be connected (recommended).
The air supply (3) of the concentric part is closed by a lid ø150mm.
The flue gas outlet connection (2) has a diameter of ø100mm.
7.2 Concentric boiler connection
Carry out the following tasks to convert the boiler to a concentric connection.
- Remove the lid ø150 (3) from the air supply connection of the concentric connection
component (2).
- Fit the lid ø100 on the air supply opening (1) and secure it with the screw (all parts
are delivered separately in the foam wrapping underneath the boiler)
The air supply opening has a diameter of ø150mm.
The flue gas outlet connection has a diameter of ø100mm.
The flue gas outlet-/air supply system is then connected to the concentric connection
component.
