upper internal surfaces of the tubes, where
through convection heavier deposition is likely
to occur.
(e) Any deposits which may have accumulated
within the combustion chamber can be
removed with a vacuum cleaner once the
burner is removed.
Note
It is most important that a build up of deposits
is not allowed to occur as this can have an
adverse effect upon the efficiency of the heater
and reduce the life of the heat exchanger.
(f) The heat exchanger and combustion
chamber should be visually inspected for signs
of splits, cracks, and distortion.
(g) All gaskets should be checked to ensure
that they continue to provide a gas tight seal, if
there is an element of doubt then they should
be replaced.
If the condition of the heat exchanger gives
cause for concern the Service Department
at Benson Heating should be advised
pending a more detailed examination.
Electrical Supply
All connections must be checked to ensure
that they are secure, and free from corrosion.
Terminals and connections should also be
checked to ensure that no stray strands are
bridging terminals.
Electrical continuity should also be checked.
Oil Supply
The oil supply pipe work, tank, and fittings
should all be inspected to ensure that they are
free from corrosion, and to ensure that where
brackets have been fitted these remain secure
and offer adequate support.
The oil filter should be replaced with a new
one, and the system should be checked for
leaks.
If the oil level is such to allow removal of any
sludge or other contaminants form the tank this
too should be undertaken, particularly if there
have been problems of poor firing associated
with contaminants reaching the burner.
Note
Any waste oil or sludge must be disposed
of correctly. Never dispose of it by
dumping or tipping it down drains or into
water courses where ground water can
become polluted and environmental
damage caused.
Burner
Service requirements for the burner fitted to
the heater are covered in the separate manual
prepared by the burner manufacturer.
