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.

Fit a drain cock to either of the primary cold

feed/drain points (B).

Check that all unused sockets have been

capped.

OIL SUPPLY CONNECTIONS:

Route oil supply pipe (D) along either side of the

boiler as required, finishing close to the burner.

Avoid hot surfaces.

Connect the oil supply pipe (D) 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 (G)

flexible push fit connector and terminate to

waste.

Do not use any solvents, adhesives or

lubricants when pushing the pipe into the

rubber connector.

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 (K).

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 (M) and

secure with screws (L).

IMPORTANT: The condensate trap must be

correctly filled to prevent the possibility of

potentially harmful flue products escaping

via the condensate pipework.
