Preparing the installation
Danger!
Risk of poisoning due to escaping flue
gas.
If you select an unsuitable installation site for
the air/flue pipe, flue gas may be allowed to
enter the building.
▶
Observe the existing regulations with re-
gard to the clearances to windows and
ventilation openings.
Danger!
Risk of poisoning due to escaping flue
gas.
Condensate that collects in a particular place
can damage the flue gas pipe seals.
▶
Lay the horizontal flue pipe with a down-
ward gradient of 3° to the product; 3° cor-
responds to a downward gradient of ap-
prox. 50 mm per metre of pipe length.
▶
In doing so, note that the air/flue pipe
must be centred in the wall hole.
▶
Determine the installation site for the air/flue pipe.
▶
When installing the product near a light source, point out
to the operator that they must clean the opening regu-
larly. Otherwise, due to the insects that the light may at-
tract, the opening may become dirty.
