1. SERVICING INSTRUCTIONS

To ensure efficient safe operation, it is recommended that the boil-
er 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 the Installation Manual
for 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).

1.1 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 chapter 2 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.

1.2 To Gain General Access

All testing and maintenance operations on the boiler require the
control panel to be lowered. This will also require the removal of
the casing.
1.2.1 Removing the front pannel:
1. Remove the screw "A" from the centre of the top edge of the
front panel and remove the panel by lifting upward
(see fig. 1.1);
2. Remove the front panel from the rest of the casing
(see fig. 1.2).
