Fig. 4.2: Example of installation with horizontal air/flue duct
IMPORTANT:
The air/flue duct is not concentric
and the air duct has a slope of 1.5°
(if the air flue duct is not cut). The
hole through the wall can therefore
be drilled horizontally with no slope.
Where extensions are used, these
must be installed with a slope at 3° ±
1° (equivalent to 50 mm ± 20 mm
rise per metre length) to ensure that
condensate dows not remain in the
sleeve.
