18. 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 Section 15.8).
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).

18.1 Replacement of Parts

The life of individual components vary and they will need
servicing or replacing as and when faults develop.
The fault finding sequence chart in Section 19 will help to locate
which component is the cause of any malfunction, and
instructions for removal, inspection and replacement of the
individual parts are given in the following pages.
