10. SERVICING INSTRUCTIONS

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).
