Condensate drain from the condensing boiler
and the flue
To ensure the condensate created in the flue can drain
via the condensing boiler, route the flue inside the
installation room with a slight fall (
≥
3°, i.e. approx. 5 cm
height differential per metre) towards the gas
condensing boiler.

5.4.2
Condensate drain from a moisture-resistant
chimney
With moisture-resistant chimneys (suitable for
condensing boilers), drain the condensate in
accordance with the chimney manufacturer's
instructions.
Via a stench trap with funnel, the condensate from the
chimney can be routed into the building drain together
with the condensate from the gas condensing boiler.
Observe all relevant regulations concerning
the building's drains, as well as local
regulations. Ensure particularly that the
drain line is vented in accordance with
regulations and that it terminates
freely
in a
drain outlet with a siphon (
Æ
Fig. 26). As a
result, the stench trap cannot be drained,
and backing up of condensate inside the
appliance is prevented.
