CONDENSATE CONNECTION:
Connect 21.5mm polypropylene pipe (K)
(not supplied) to the condensate pipe flexible
push fit connector (J) before terminating
to waste.
Do not use any solvents, adhesives or
lubricants when pushing the pipe into the
rubber connector (J).
Ensure that the condensate pipe runs away
from the boiler at a constant fall of 50mm
(min.) for every metre.
Carefully pour 500ml of water into the
condensate collection (S) to fill condensate trap.
Check the water is running away and the
condensate pipework joints are water tight.
Check the flue manifold seal is undamaged
and seated correctly.
Refit flue manifold access cover ( T ) and
secure with screws (U).
IMPORTANT: The condensate trap must be
correctly filled to prevent the possibility of
potentially harmful flue products escaping
via the condensate pipework.
PRESSURE RELIEF CONNECTION:
Connect the pressure relief pipe (M) to a
copper discharge pipe (15mmØ min.) and
terminate externally to the appliance casing.
Blank all unused casing holes with the bungs
or cover plates and seals supplied. The
drain/fire valve capillary hole covers should
be rotated so that the unused capillary slot is
covered by the cover plate and seal.
Refit rear panel.
Seal all joints where pipes pass through the
casing, with suitable waterproof sealant.
IMPORTANT: Insulate all
external condensate pipe
work or run in 32mm pipe
work to prevent freezing.
