Note
■ Connect condensate pipe A with a
pipe vent to the domestic waste
water system, routing it inside the
building as far as possible.
■ If the condensate pipe is routed out-
side the building, use a pipe with
min. 7 30 mm and protect it from
frost. Avoid long external pipe runs.
!
Please note
A frozen condensate pipe can
result in faults and damage to
the boiler.
Always protect condensate
pipes against frost.
■ Observe local building regulations.
Installation sequence
(cont.)
1. Pull condensate pipe A out of the
appliance far enough to prevent
unnecessary bends inside the
appliance. Ensure that the trap is
properly connected.
2. Connect condensate pipe A to the
public sewage system with a con-
stant fall and a pipe vent.
Observe local waste water regula-
tions.
