To ensure efficient safe operation, it is recommended that the boiler
is serviced annually by a competent person.
Before starting any servicing work, ensure both the gas and
e
lectrical supplies to the boiler are isolated and the boiler is
cool.
Before and after servicing, a combustion analysis should be made
via the flue sampling point (please refer to
SECTION 3.4 for further
details).
After servicing, preliminary electrical system checks must be carried
o
ut to ensure electrical safety (i.e. polarity, earth continuity,
resistance to earth and short circuit).
