C-Hole in the wall Zero Clearance Kit (Dimensions)
Hole in the wall Zero Clearance Kit.
Please note the Zero clearance kit is designed to work in conjunction with standard Plaster and skim plaster
finish. This doesn’t remove the possibility of settlement which could result in cracking of the plaster finish over
a period of time.
Ensure it is a suitable outside wall constructed of non-combustible materials and that the flue position meets
the requirements previously described.
Mark a vertical line on the wall at the intended centre of the appliance up from the horizontal line for a height
of 489mm. Using a long masonry drill, make one pilot hole completely through the wall. Ensure the hole is
drilled accurately at the centre and square to the wall both horizontally and vertically at the cross point
previously marked.
Cut out the brickwork of the inner skin of the cavity wall for the lintel, and fix the lintel. Cut out the brickwork
under the lintel, between the two outside vertical lines into the cavity. Ensure the cut out width is square and
try the appliance into the opening.
Using 150mm core drill cut a hole following the pilot hole. Drill from the outside through to the cavity to give
a good finish on the outside. Remove any cavity insulation from the cut out opening and for a further
100mm into the cavity gap each side and above.
Pack “Rockwool” around the sides and top of the
opening into the cavity for a depth of 100mm. Also put some behind the firebox if space is available.
