INSTALLER’S GUIDE

5. PREPARE THE WALL
The flue must be installed so that it is at
right angles to the back panel of the fire all
round the flue circumference. The fire
itself should be fitted vertically against a
flat wall. Where this is difficult to achieve
due to building inaccuracies care should be
taken to ensure that the back of the fire is
not stressed in any way due to distortion of
the assembly when tightening the fixing
screws. Where necessary, non-
combustible packing pieces should be used
to provide a satisfactory fixing surface.
Before cutting the hole in the wall make
sure that the height to the top surface of
the finished floor is known. The minimum
acceptable height from this surface to the
flue hole centre is shown in figure 5.
If a loose hearth or plinth is to be used, the height from its top surface must be used when
determining the minimum flue height. Where installation is to a timber frame wall, the
appliance should be positioned so that the right side wall fixings are into timber studs to
absorb any pressure generated by operating the control knob.
Proprietary cavity fixings should be used at the left side if the fixing at this side is into
plasterboard.
5.1
Place dustsheets on the floor and over any furnishings etc.
5.2
Place the template against the wall. Make sure that the centre of the flue hole is not
less than the minimum shown in figure 5.
5.3
Pierce the centre of the screw fixing holes and the flue hole and mark the positions
on the wall.
Remove the template.
5.4
Cut the hole for the flue unit. Make sure that it is straight and level. Though a
hammer and chisel can be used, using a core drill is by far the quickest and simplest
method for normal brickwork.
5.5
Core Drilling
5.5.1
Drill a pilot hole through the wall. Inspect the hole to ensure that it is in the
brickwork and not in mortar. If it is in mortar, it is advisable to reposition the hole
approximately 25mm away (making sure that the minimum side clearances and height are
complied with). Remember to reposition the screw fixing holes.
