Concentric pipes (ø 60-100mm)
Fig. 22
To connect the concentric pipes, use the specific adaptor
supplied as an accessory.
The frame spacer kit must be utilized for the wall-mounted
rear concentric discharge (see the Catalogue).
The concentric pipes can face in the direction most suit-
able for installation requirements, but special attention
should be paid to the external temperature and the length
of the pipe.
b
Make sure the flue gas discharge pipe is tilted 3° to-
wards the boiler.
b
Uninsulated flue pipes are potentially dangerous and
can cause burns.
b
Never obstruct or partly choke the comburent air in-
take pipe.
For installation, follow the instructions supplied with the kit.

The use of longer pipes reduces the boiler output.
For installation, follow the instructions supplied with the
specific accessory kit for condensing boilers.
