CONNECTIONS - PLUMBING
CONDENSATE DRAIN
A drain line must be fitted to the condensate drains to carry the discharge clear
of the water heater. The drain line can be extended using 20 mm or 40 mm O.D.
rigid hose or conduit (refer to "Connection Sizes" on page 50).
Where installed externally, the drain line pipe work must be UV resistant or
protected from sunlight. The outlet of the drain line must be in such a position
that flow out of the pipe can be easily seen - but arranged so water discharge
will not cause damage or nuisance. The water heater is supplied with fall and t
is recommended to install the water heater with a slight fall towards the
condensate drain.
The condensate drain must not be connected to the pressure relief or
expansion control valve drain line but may discharge at the same point.
