WATER CONNECTIONS:
Remove the transit bungs from the pipework
connections on the boiler.
NOTE: That surplus water may be present
due to factory testing.
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 (D) along either side
of the boiler as required and connect to the
isolating valve (E), ensure the valve is closed.
*NOTE: Replace flexible hose at annual
service to prevent possible oil leakage.
Connect the flexible oil hose (F) to the
isolating valve (E).
CONDENSATE CONNECTION:
Connect 21.5mm polypropylene pipe ( J ) (not
supplied) to the condensate waste pipe
flexible push fit connector (G) and terminate to
waste.
Do not use any solvents, adhesives or
lubricants when pushing the pipe into the
rubber connector (G).
Ensure that the condensate pipe runs away
from the boiler at a constant fall of 50mm
(min.) for every metre.
Seal all condensate pipe joints.
Carefully pour 500ml of water into the
condensate collection ( O ) 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 (N) and
secure with screws (M).
IMPORTANT: The condensate trap must be
correctly filled to prevent the possibility of
potentially harmful flue products escaping
via the condensate pipework.
