4.6 CONDENSATE DISPOSAL
Condensation is formed in the normal operation of the heater and this must be continuously discharged into
a drain. Given the acidity level of condense discharge (pH 3.5 - 4.5) only plastic material can be used for the
discharge pipe work. A 60kW heat engine can produce up to 6.0 litres of water per hour, whilst at full load.
Use of 40mm plastic pipe with a drop of at least 30 mm for every metre of pipework is recommended. A trap is
supplied which should be connected into a drain via a tundish or air break.
External pipework and that passing through a wall to the outside should be run in a minimum of 40mm diam-
eter. External pipework should be insulated to protect against frost and freezing temperatures.
The condensate trap must be fi lled with water before operating the heater.
It is important that the condensate fl ow must be maintained, even in freezing conditions. In
the event that the condensate becomes blocked, the heater will shutdown completely, and
will not operate again until the
fl ow has been restored.
Soil / Vent Stack
There is no requirement for an additional trap or air
break when connecting drain pipework to an inter-
nal or external soil or vent stack
Gully
There is no requirement for an additional trap
if discharging direct into an open gully.
