INSTRUCTIONS

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.

1.1 REPLACEMENT

OF PARTS

1.2 TOGAIN 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.

To lower the control panel and dismantle the front part of the casing,

proceed as follows:

1. Unscrew screws “A” (1/4 turn only) (FIG. 1.1 + FIG. 1.2) and rotate the

control panel forward;

2. Unscrew the screws “B” (FIG. 1.3) and unhook the front panel by lifting it.

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).
