Connecting the flue gas outlet
Connecting the air supply
With a room-ventilated version, the air supply opening stays open; only the
flue gas outlet opening is connected. This will ensure that the boiler
obtains the necessary combustion air directly from the installation area.
Use adapters when using air supply and flue gas outlet pipes with any
other diameter.
Caution
The air supply opening must stay open.
The installation area must be equipped with the necessary air
supply openings. These openings must not be obstructed or
shut off.
