Servicing Instructions - Chaffoteaux & Maury BRITONY SX 14 FF Installation, Servicing And User's Manual

6. SERVICING INSTRUCTIONS

To ensure efficient safe operation, it is recommended that
the water heater is serviced annually by a competent per-
son.
Before starting any servicing work, ensure both the gas
and electrical supplies to the water heater are isolated
and the water heater 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).
7. 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 8 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.
