Concentric pipes

Two types of adapters are available for the coaxial pipes (A) and (B). The vertical pipe permits the insertion of a vertical
concentric pipe or a concentric pipe with a 90° or 45° elbow that makes it possible to connect the boiler to the exhaust-intake
pipes in any direction, thanks to the possibility of 360° rotation. The fitting (B) is a 90° concentric elbow designed for use in
installations where the upper space between the boiler and the wall-mounted exhaust is reduced.
Fig.112 Concentric exhaust-intake type
The 90° elbow makes it possible to connect the boiler to exhaust and intake pipes, adapting it to different requirements.
It can also be used as an additional elbow in combination with the 45° pipe or elbow.
If discharging to the outdoors, the exhaust-intake pipe must exit at least 18 mm from the wall in order to position the washer and
its sealing to prevent water infiltration.
