PART 4: PREPARING FOR INSTALLATION
Check ignition spark
Before attempting to install, it is worth checking that the piezo electric spark
ignition system operates satisfactorily.
To initiate the spark, depress the control knob and while keeping it depressed, turn
anticlockwise through approximately 60° to the “PILOT/IGN” position. A spark
should track from the electrode pin to the thermocouple tip. If there is no spark or
incorrect tracking, check the spark gap between the electrode wire and
thermocouple tip (see figure 5). If the spark gap is correct, check the ignition wiring.
In the majority of cases, the burner unit will need to be detached
.
(
see page 26)
Detach the burner unit from the firebox, by removing the support bracket fixing
screw at the lower front region of the burner unit. Lift and withdraw the unit. (See
figure 6).
PART 5: WALL PREPARATION
General
Make sure that the installation will comply with all the relevant requirements in part 2
of this manual.
Attempt to keep the hole sizes as close to the minimum dimensions as possible in order
to minimise the sealing required
Make sure that the or any electrical wiring, piping etc. in the wall is not affected when
cutting the installation hole
.
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)
Brick, Stone Etc. Building. Main Case In Front Of Wall
(Figure 7)
This installation is for use with a fire surround or false chimney breast having a
minimum depth of 140mm (5¼in.). The flue length may be cut to suit the wall
thickness.(see prepare flue assembly section) Combustible material within a false
chimney breast must be at least 75mm from the fire box.
The non-combustible hearth must project at least 345mm in front of the
convection box front flanges and be at least 625mm wide (Figures 1 & 7).
The cavity should be sealed where the flue tube hole has been cut. We
recommend filling fully across the cavity with Rockwool or equivalent to at least
100mm around the opening. (See figure 11 )
