Concentric pipes (ø 60-100mm)
Fig. 25
To connect the concentric pipes, use the specific adaptor
supplied as an accessory.
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
Arrange the flue gas discharge pipe so it slopes by
1% towards 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.

Twin pipes (ø 80mm)
Fig. 27
The concentric pipes can be fitted in most suitable direc-
tion in relation to installation requirements.
b
Arrange the flue gas discharge pipe so it slopes by
1% towards the boiler.
b
The use of longer pipes reduces the boiler output.
For installation, follow the instructions supplied with the
specific accessory kit for condensing boilers.
