î
Make sure to insulate the
fl ue piping in damp rooms
to avoid condensation water
from forming and dripping.
î
Cut the pipes squarely and deburr the
edges. This will ensure correct sealing
and prevent seals from being damaged.
î
To ease the assembly of pipes, use exclu-
sively a mixture of water and soap (1%)
on the extremity of the pipe to be fi t in.
î
Metal fl ue pipes should always be fi t-
ted into the sleeve to the end stop.
i
Installing the pipes - General principles
î
Flue pipe elements or PP air
inlet elements should not be
screwed together.
î
Piping elements should not be bond-
ed together using glue (e.g. silicone) or
foam (e.g. PUR).
î
Plastic fl ue pipes should be
allowed to expand under the
eff ect of heat. Leave about
10 mm between the pipe and
the sleeve end stop.
î
The fl ue system should be fi tted with an
inspection opening.
î
Do not exceed the maximum length rec-
ommended for the product when con-
necting the fl ue pipes, or the system pow-
er might decrease.
î
For B- and C-type appliances, the fl ue gas
exhaust pipes must at least comply with
the category T120 H1 W1/2 O30 LI E U
when using parallel piping and T120 H1
W1/2 O00 LI/LE E U0 when using concen-
tric piping (EN 14471).
î
The maximum length of duct must be
calculated according to the permissible
diff erence in pressure indicated in the
technical specifi cations.
