6.5 Condensate discharge
The condensate discharge pipe is on the bottom of the heater. The separate delivered siphon
has to be connected to the condensate Ø40mm PVC pipe. On the siphon a pipe Ø 40mm can
be mounted. The discharge system after the sifon has to be minimum Ø25mm and mounted
with an inclination to the sewer. The advised inclination should be minimum 30mm per meter.
The horizontal length should not exceed 5 meter.
The condensate should connected according to local and national regulations. Do not let the
condensate drip on the roof or roof edge outside the building, dangerous ice can be formed in
the winter. Condensate should be drained away to the sewer.
The condensate outlet from the heater should never be closed.
Protect the condensate drain from freezing. Ice can also close the condensate drain.
To be sure that the condensate can always flow out of the heater, an extra siphon should be
mounted before connecting to the sewer.
When the condensate discharge system is placed the siphon has to be filled with water. This is
important because otherwise the flue gases can flow into the room where the heater is placed.
