Ignition Spark Check
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
3. If the spark gap is correct, check the ignition wiring.

Fireplace Condition Check
The fireplace must comply with all the requirements of section 4.
5.3.1
Fireplace General Condition
The fireplace floor should be reasonably flat to ensure that the convection box can be
installed without it rocking and so that a good seal can be made at the bottom front of the
box. The front face of the fireplace should be reasonably flat over the area covered by the
convection box top and side flange seals to ensure good sealing. These faces should be
made good if necessary. If the appliance is to be fitted against a wall with combustible
cladding, the cladding must be removed from the area covered by the outer surround (see
figure 1). We suggest that the actual surround be used as a template to mark the area for
combustible cladding removal.
5.3.2
Soundness for appliance attachment
Two primary methods of retaining the appliance are provided: -
1)
By fixing to the fireplace front.
2)
Using concealed tension cables fixed to the rear of the fireplace opening together
with secondary fixing to the fireplace floor.
The methods are detailed in section 8 of this manual. Before selecting the retention
method, consult with the customer. Method 2 is provided for instances where drilling
holes in the front surface of the fireplace surround is unacceptable to the customer or
otherwise impractical. N.B. It is unwise to attempt to drill into marble without the proper
tools and equipment.
If method 1 is chosen, make sure that the fireplace front surround area is sound enough to
take the rawlplugs and woodscrews. If necessary, make sound with a suitable cement.
If method 2 is chosen, make sure that the areas at the back and towards the centre of the
fireplace floor are sound enough to take the eyebolts and screws. If these areas have
deteriorated due to prolonged use, they should be made sound with a suitable cement.
5.3.3
Installations using a metal flue box
The whole of the top surface of the metal flue box must be covered with a layer of
mineral wool or equivalent insulation at least 100mm thick. See figure 1.
