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
electrical 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 S
further details).
After servicing, preliminary electrical system checks must be car-
ried out to ensure electrical safety (i.e. polarity, earth continuity,
resistance to earth and short circuit).
