9 Condensate & Safety Discharge Valve Connections
9.1 Safety Discharge Valve
The pipes must be extended, using not less than 22mm o.d.
pipe, to discharge, in a visible position, outside the building,
facing downwards, preferably over a drain.
The pipe must have a continuous fall and be routed to a
position so that any discharge of water, possibly boiling,
or steam cannot create any danger to persons, damage to
property or external electrical components and wiring.
It is advisable to use a 22mm compression elbow to aid in
future servicing, see diagram 9.1.

9.2 Condensate Drain Connection
A flexible condensate hose runs from a push-fit connection
at the bottom of the heat exchanger and terminates on the
boiler module base plate, see diagram 8.2.
Connect the flexible condensate hose to the boiler module,
see diagram 9.2.
A flexible condensate connection pipe is supplied in the
loose items pack and should be fitted between the condense
trap & siphonic drain to the condensate drain pipe, see
diagram 9.3, and refer to section 6 to discharge condensate
to a drain. The drain pipe 22mm to 25mm OD. non corrosive
plastic pipe should have a fall of at least 2.5
boiler.
