Connecting the condensate discharge pipe

Important
For C 630 ECO: the properties described and the instructions
apply to each boiler module.
1. Fit a plastic drain pipe of Ø 32 mm or larger to the siphon, terminating
in the drain.
Caution
Use only plastic material for the discharge pipe due to the
acidity (pH 2 to 5) of the condensate.
Do not make a fixed connection in order to prevent an
overpressure in the siphon.
2. Fit a stench-trap or siphon in the drain pipe.
Caution
Never seal the condensate drain.
The drain pipe must slope down at least 5 - 10 mm per metre,
the maximum horizontal length is 5 metres.
Condensed water must not be discharged into a gutter.
Important
For C 630 ECO: the properties described and the instructions
