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 fascia. The
cladding must also not touch the fascia (See figure 4). We suggest that the fascia is used
as a template to mark the area for combustible cladding removal and that this area is
increased by at least 2mm all round.
5.1.3
Soundness for appliance attachment
Two primary methods of retaining the appliance are provided: -
1)
By fixing to the fireplace front surround.
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 9 of this guide. 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 front surround area is sound enough to take
the wall plugs and wood screws . 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 eyescrews and wood screws . If these areas
have deteriorated due to prolonged use, they should be made sound with a suitable
cement.
5.1.4
Installations using a metal flue box
The whole of the top surface of the metal flue box must be covered with a minimum
100mm layer of mineral wool or equivalent insulation (See figure 2).
5.2 Fireplace flue pull.
Close all doors and windows in the room in which the appliance is to be installed. After
confirming with a match that smoke is drawn into the flue, light a 13 gram smoke pellet
and check that there is a definite flow through the flue. Verify outside that the smoke
exits from one terminal only and that the termination is suitable. Observe, where
possible, upstairs rooms and loft spaces for signs of escaping smoke indicating a
defective flue. If there is not a definite flow warm the flue for a few minutes and repeat
the smoke pellet test. If there is still no definite flow the flue may need remedial work –
Do not fit the appliance until there is a definite flow through the flue.
