4.1CHECK 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 3). If the spark
gap is correct, check the ignition wiring.

CHECK THE FIREPLACE
The fireplace must comply with all the requirements
of section 2.
4.2.1
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 1c). We suggest that the actual
A nut and olive are provided for an 8mm pipe inlet connection
to the elbow at the bottom front of the appliance. The elbow
can be rotated to allow a connection from any direction. The
elbow includes a valve for isolating the gas supply.
The supply pipe must be rigid material. Flexible pipe must not
be used.
5.1
CONCEALED
CONNECTION
If a concealed connection from inside the fireplace is
required then, before the appliance is fitted into
the fireplace it will be necessary to extend the
supply line so that it will project through the sealed
opening at the back of the convection box (near the
left side) and run to the elbow at the front
The pipe run from the supply line up to the rear
opening in the convection box must be kept clear of

surround is used as a template to mark the area for
combustible cladding removal.
4.2.2
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 7 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.
4.2.3
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
1b).
4.3
FIREPLACE FLUE PULL
After preparing the fireplace, apply a lighted match,
paper or smoke match to the chimney opening.
Observe the smoke. If there is a definite flow into the
opening continue with the installation. If there is not
a definite flow, preheat the chimney for a few
minutes and recheck If there is still no definite flow,
the chimney may need attention. Do not fit the
appliance. Seek expert advice.
the area which will be taken by the convection box
when it is installed. A template is supplied to aid the
installation of the pipe run.
We recommend the following method for installing
with a concealed supply pipe:
5.1.1
Cut the template to the shape shown by the "Debris
catchment area". Note that the areas are different for
fireplaces with conventional brick flues and precast
flues.
5.1.2
Place the template on the fireplace floor (printed side
upward) with the front line level with the front
surface of the fireplace. The centre line of the
template should line up with the centre of the
fireplace. Tape the template securely in this position
5.1.3
Make sure that the fireplace is clear of all material
over the full area covered by the template including
that marked "Debris catchment area".
