8. SERVICING
I
MPORTANT: ISOLATE ELECTRICAL SUPPLY TO THE
BOILER BEFORE SERVICING
To maintain the boilers 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.
Note:
It is a requirement of the boiler’s guarantee that an
annual service is 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 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.
