fascia. The cladding must also not touch thefascia (See figure 4). We suggest that the
actual 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
A primary method of retaining the appliance is provided: -
Using concealed tension cables fixed to the rear of the fireplace opening.
The method is detailed in section 9 of this manual. Make sure that the areas at the back
of the fireplace are sound enough to take the eyebolts. 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
50mm 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.
6. IGNITION CHECK
Before attempting to install, it is worth checking that
the ignition system performs satisfactorily.
Set the control knob to the ‘OFF’ position.
Depress the control knob and rotate it anticlockwise
to the pilot ignition position. A 'click' will be heard
as the integral piezo operates. A spark should be seen
between the electrode and pilot tip
.
If there is no
spark check the following: -
!
Ensure that the electrode lead is connected to the
terminal at the base of the electrode.
!
If the above is correct, check for damage to the
electrode lead.
