SERVICING INSTRUCTIONS

To ensure efficient safe operation, it is recommended that the
boiler is serviced annually by a competent person, refer to
Section 20 (page 54) for the Servicing Schedule.
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.
After servicing, preliminary electrical system checks must be
carried out to ensure electrical safety (i.e. polarity, earth
continuity, resistance to earth and short circuit).
