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 the Installation Manual for further details).
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).
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.
All testing and maintenance operations on the boiler require the control panel
to be lowered. This will also require the removal of the casing.
To dismantle the front part of the casing, proceed as follows:
1. Loosen the two screws "A" located on the bottom part of the boiler until
the first thread on the screws appears (Fig. 1.1) ;
2. Lift the front panel up until it stops with a click and remove the front
panel from the rest of the casing (Fig. 1.2) ;
4. Unhook the two cords from the locating slots (Fig. 1.3) .
