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.
