INSTALLER GUIDE

6. FIREPLACE CHECK

6.1 Soundness for appliance attachment.
Two primary methods of retaining the appliance are provided: -
1) By fixing to the fireplace front surround.
2) Using concealed fire retaining cables fixed to the rear of the fireplace opening
together with secondary fixing to the fireplace floor.
The methods are detailed in section 10 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 fibre / wooden plugs and wood screws. If necessary, make sound with
suitable cement.
If method 2 is chosen, make sure that the areas at the back and base are sound
enough to take the eyebolts and wood screws. If these areas have deteriorated due
to prolonged use, they should be made sound with suitable cement.
6.2 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.
