INSTALLER GUIDE

5. FIREPLACE CHECK

5.1 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 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 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 suitable
cement.
If method 1 is chosen, make sure that the front surround area is sound enough to
take the fibre plugs and woodscrews. If necessary, make sound with suitable cement.
5.1.1 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 5).
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.
