1. If a DHW safety valve is connected,
connect hose
L
to the safety valve
drain.
Note
If no DHW safety valve is connected,
do not change the position of hose
L
(serves as a vent).
2.
Route condensate hose
M
to the
back (drain in wall G ) or to side aper-
ture H (see page 8).
Note
Pull the condensate hose far enough
out of the boiler that no unnecessary
bends are created inside the boiler.
3. Route condensate hose M as a U-
bend and connect with a constant fall
and a pipe vent to the public sewage
system or to a neutralising system.
If necessary, connect to an on-site
siphon. Ensure this connection is
secure.

■ The condensate pipe is connected
with the discharge pipe of the safety
valve. The condensate hose supplied
meets the temperature requirements
that are part of the CE certification.
■ We recommend the internal connec-
tion of the condensate pipe to the
domestic drain, either directly or via a
tundish.
■ If the condensate pipe is routed out-
side the building, use a pipe with at
least
7
30 mm and protect this pipe
from frost. Avoid long external pipe-
lines.
!
Please note
Frozen condensate pipes can
result in faults and damage to
the boiler.
Always insulate condensate
pipes against frost.
■ Observe local building regulations.
