1.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 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).
1.1REPLACEMENT OF PARTS
The life of individual components varies 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.
1.2TO 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.
Removing the front panel
1.Loosen the fastening screws “A” of the control panel located on the lower part of the panel itself. (FIG. 1.1);

2.The control panel moves downward and when pulled forward, rotates on two lateral hinges; the panel stays in a semi- horizontal position, which allows access to the inner parts of the boiler (FIG. 1.2);
3.In order to increase the manouvering space, it is possible to raise the control panel and rotate it to a fully horizontal position (FIG. 1.3);
4.Remove the screws “B” from the front panel bottom lip (FIG. 1.4);
5.Lift the front panel from the raised screws at the the top of the casing (FIG. 1.5).
