WATER CONNECTIONS:
Remove the transit bungs from the pipework
connections on the boiler.
NOTE: That surplus water may be present
Remove the central heating flow pipe (A)
from its packaging. Grease the flat washer
with the grease supplied and fit the pipe and
washer onto the isolation valve as shown.
Ensure all pipework is clean.
Align water pipework and connect, ensuring
that the expansion tank and control box fit
correctly before permanently connecting the
H
pipework.
N
Check that all unused sockets have been
J
capped.
OIL SUPPLY CONNECTIONS:
Route the oil supply pipe (E) along either side
K
of the boiler as required and connect to the
isolating valve (F) and ensure the valve is closed.
*NOTE: Replace flexible hose at annual
service to prevent possible oil leakage.
Connect the flexible oil hose (G) to the
isolating valve (F).
CONDENSATE CONNECTION:
Connect 21.5mm polypropylene pipe (K) (not
supplied) to the condensate waste pipe
flexible push fit connector (J) and terminate to
waste.
E
Do not use any solvents, adhesives or
L
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.
1m
Seal all condensate pipe joints.
Carefully pour 500ml of water into the
condensate collection ( T ) to fill condensate trap.
50mm (min.)
Check the water is running away and the
condensate pipework joints are water tight.
K
Check the flue manifold seal is undamaged
and seated correctly.
Refit flue manifold access cover (S) and
secure with screws (Q).
