5.6 Pipework connections
Water connections
▶ Ensure all pipework is clean.
▶ Align water pipework and connect
▶ Check that all unused sockets have been capped.
Oil supply connections
▶ Route the oil supply pipe [W] along either side of the boiler as
required and connect to the isolating valve [G] and ensure the valve
is closed.
▶ Connect the flexible oil hose [H] to the isolating valve [G].
Condensate connection
▶ Connect 21.5mm polypropylene pipe [L] (not supplied) to the
condensate waste pipe flexible push fit connector [K] and terminate
to waste.
▶ Do not use any solvents, adhesives or lubricants when pushing the
pipe into the rubber connector [K].
▶ Ensure that the condensate pipe runs away from the boiler at a
constant fall of 52mm (min.) for every metre.
▶ Seal all condensate pipe joints.
▶ Carefully pour 500ml of water into the condensate collection [U] 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 [S].
Pressure relief connection
▶ Connect the pressure relief pipe [N] to a copper discharge pipe
(15mm Ø min.).

CAUTION: Isolate the oil & water mains supply before
starting any work and observe all relevant safety
precautions.
Water may be present, due to factory testing.
The condensate trap must be correctly filled to prevent
the possibility of potentially harmful flue products
escaping via the condensate pipework.
1) Replace flexible hose at annual service to prevent possible oil leakage.
