4. THE FIREPLACE
4.1
In the United Kingdom the fireplace must comply with the
requirements described in section 2.2. The debris catchment area
shown in figure 8 must be kept clear of obstructions.
4.2
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 fire front surround (see figure 3). We suggest that the actual
fire front is used as a template to mark the area for combustible
cladding removal.
4.3
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 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 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.
4.4 Installations using a metal flue box
The whole of the top surface of the metal flue box must be covered with a 100mm layer
of mineral wool or equivalent insulation (see figure 2).
4.5 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.
