Condensate Drain From The Condensing Boiler And The Flue; Condensate Drain From A Moisture-Resistant Chimney - Buderus Logamax plus GB162 Technical Manual

7 Condensate drain
7.1.1 Condensate drain from the condensing
boiler and the flue
To ensure the condensate generated in the flue can drain
via the gas condensing boiler, route the flue inside the
installation room with a slight slope (≥ 3°, i.e. approx. 5 cm
height differential per metre) towards the gas condensing
boiler.
Observe the relevant regulations concerning
waste lines from buildings and appropriate
other local regulations. Ensure particularly
that the drain line is ventilated in accordance
with regulations and that it drains freely
( fig. 83) into a drain outlet with a siphon,
to prevent the stench trap being emptied and
to prevent condensate from backing up into
the appliance.

chimney
Drain condensate in accordance with the details
specified by the chimney manufacturer in the case of a
moisture-resistant chimney (suitable for condensing

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.
