6. PREPARING FOR INSTALLATION
Check ignition spark.
Before attempting to install, it is worth checking that the
ignition system performs satisfactorily.
!
Set the control knob to the off position.
!
Depress the control knob and rotate it anticlockwise to the
pilot ignition position. A 'click' will be heard as the integral
piezo operates. A spark should be seen between the electrode
and pilot tip (See figure 6)
.
If there is no spark check the following: -
!
Ensure that the electrode lead is connected to the terminal
at the base of the electrode.
!
If the above is correct, check for damage to the electrode
lead.
In the majority of cases, the burner
unit will need to be detached. Detach
the burner unit from the convection
box by removing two screws (See
figure 7). Carefully lift the burner unit
out from the hotbox and place
immediately in front of the hotbox. Do
not attempt to lift the burner module
away from the front of the firebox as
this may damage the solenoid leads.
Disconnect the solenoid leads from the
control box.
7. WALL PREPARATION
7.1 General.
1. Make sure that the installation will comply with all the relevant requirements in part
3 of this manual.
2. Attempt to keep the hole sizes as close to the minimum dimensions as possible in
order to minimise the sealing required.
3. Make sure that the damp course or any electrical wiring, piping etc. in the wall is not
affected when cutting the installation hole.
4. Any gas supply pipe installed in the wall, floor or cavity of a cavity wall must be
continuous and enclosed in a factory fitted gas tight sleeve (Ref: Gas safety (Installation
& Use) Regulations 1994 as amended & Certificate of exemption no.1 1996)
