prevent a direct contact with condensa-
tion from the boiler. The products of
combustion must be conveyed through a
flexible or rigid plastic pipe around 100
to 150 mm in diameter, and condensa-
tion must be siphoned off at the foot of
the pipe. The usable height of the water
trap must be at least 150 mm.

FORCED EXHAUST
(Type B23P-53P)
This type of exhaust pipe is installed using
the special kit, code 8089911. For kit
assembly instructions, refer to point 2.6.
Protect the intake with the optional acces-
sory, code 8089501.
The accessory is assembled by cutting a 50

extension and inserting it on the air intake,
on which the accessory is then fitted,
anchored to the pipe segment with the
