… coaxial flue - air duct (concentric)
This type of duct allows to disengage exhaust gases
and to draw combustion air both outside the
building and in case a LAS flue is fitted.
The 90° coaxial bend allows to connect the boiler
to a flue-air duct in any direction as it can rotate by
360°. It can moreover be used as a supplementary
bend and be coupled with a coaxial duct or a 45°
bend.
If the flue outlet is placed outside, the flue-air
ducting must protrude at least 18mm out of the wall
to allow alluminium weathering tile to be fitted and
sealed to avoid water leakages.
Ensure a minimum downward slope of 1 cm
towards the outside per each metre of duct length.
A 90° bend reduces the total duct length by 1 metre.
A 45° bend reduces the total duct length by 0.5 metre.
