6. SERVICING

IMPORTANT: ISOLATE ELECTRICAL SUPPLY TO THE
BOILER BEFORE SERVICING
To maintain the boiler's high thermal efficiency and
reliable operation, it should be serviced annually by a
qualified engineer preferably OFTEC trained and
registered. Electrical work should be carried out by a
qualified engineer.
If the boiler is used to provide central heating and hot
water all year round, the best time for its annual service
is just before the start of the heating season.
Where the boiler is shut down for the summer months,
the service should be carried out as soon as possible
after the end of the heating season.
Oil tank
Open tank drain-cock to draw off any accumulated water
and sludge.
Line filters
Turn off oil supply and remove filter bowl. Wash filter ele-
ment clean with kerosene.
Servicing the burner
See separate leaflet 'Burner Details'.
Servicing the Boiler
(Burner removed)
1. Remove flue-cover and lift out flue-baffles
(See Fig. 12).
2. Brush all deposits from flue-baffles and internal
surfaces of the boiler.
3. Remove flue deposits from the combustion chamber
floor using a vacuum cleaner.
4. Replace flue-baffles in the correct arrangement
(See Fig. 12 for order of assembly). Refit the flue-
cover and fully tighten wing-nuts to make a gas tight
seal.
5. Refit burner to boiler, connect flexible air hose
(balanced flue boilers only) and plug-in burner lead.
6. Turn on oil supply, switch on electricity and burner
should fire.
7. Finally check the combustion readings with those
given under 'Burner Settings' and make any air or oil
pressure adjustments necessary.
