The appliance must be mounted behind a non-
combustible hearth with minimum dimensions as figure 5.
(n.b conglomerate marble hearths are considered as non-
combustible). The appliance can be fitted to a purpose made
proprietary class “O” 150°C surround. The hearth material
must be at least 12mm thick. The periphery of the hearth (or
fender) should be at least 50mm above floor level to
discourage the placing of carpets or rugs over it.
The appliance must not stand on combustible materials
or carpets.
The appliance must not be fitted directly against a
combustible wall.
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. We suggest that
the actual surround is used as a template to mark the area for
combustible cladding removal.
2.13
The flue must not be used for any other appliance or
application.
2.14
If the fireplace opening is of underfloor draught type, it
must be sealed to stop any draughts.
2.15
An extractor fan may only be used in the same room as
this appliance, or in any area from which ventilation for the
appliance is taken, if it does not affect the safe performance of
the appliance. Note the spillage test requirements detailed
further on in this manual. If the fan is likely to affect the
appliance, the appliance must not be installed unless the fan is
permanently disconnected.
2.16
Propane gas appliances must not be installed in a room,
which is built entirely below ground level
(see BS 5871 Part 2).
3. PRELIMINARY CHECKS
3.1 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 6). If the spark gap is correct, check the ignition
wiring.
3.2 CHECK THE FIREPLACE
The fireplace must comply with all the requirements of
section 2.
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. We suggest that the actual
surround is used as a template to mark the area for
combustible cladding removal.
3.3 FIREPLACE FLUE PULL
After preparing the fireplace, carry out the flue flow test as
detailed in BS5440: Part 1.
Note - A 13 gramme smoke pellet will generate the required
volume of smoke, anything smaller may give a false pass result.
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 ten minutes and recheck. If there is
still no definite flow, the chimney may need attention.
Do not
fit the appliance. Seek expert advice
.
