3.9.2. Installation Procedure for Recessed Installation
On the inside wall:
1. Measure the height of the hearth (in the
case of a raised installation ascertain the
height of the top surface of the hearth)
and mark a horizontal line on the wall at
the same height.
2. Above the hearth level draw a rectangle
to the dimensions of the recess as
detailed in Figure 17 or Figure 18. Note
that a lintel will be required above the
recess of the fire to support the inner
wall. If in doubt seek expert building
advice.
3. Cut the recess in the inner wall ensuring
that when the non combustible backing
panel/slips is in place there is sufficient
depth to accommodate the firebox.
4. Screed the floor of the recess to the level
of the hearth to allow for accurate fitting
of the firebox and flue and air supply
ducts.
5. Mark a vertical line on the outer leaf of
the cavity wall down the centre line.
From the screeded floor measure up and
mark 125mm and 470mm. At these two
points drill 125mmØ holes with a core
drill (see Figure 24).
6. Mark out, drill, plug and fit the four eye
screws onto the rear wall of the fireplace
opening as shown in Figure 24.
7. Ensure that any cavity wall insulation or
other combustible materials within the
installation are removed and replaced
with Rockwool or equivalent material.
8. At this point install the hearth, back panel
and mantel if one is to be used.
9. Bring the gas supply into the recess and
position so it lines up with the gas entry
port in the rear of the convector box. This
is situated 105 - 165mm to the right of
centre and 40mm above the screeded
floor of the recess (see Figure 24).

10. Measure the distance L between the
face side of the back panel and the
outside surface of the outer leaf through
the drilled Ø125mm holes (see Figure
30). From this figure deduct 170mm.
Cut two pieces of Ø100mm ducts to the
new figure and deburr the ends. (Note;
Two 440mm lengths of 100mmØ ducts
are supplied which is sufficient for most
inset installations. Extra lengths of ducts
up to 1000mm can be supplied. (This is
also the maximum length of ducts that is
permitted to be used.)
