clearance to any combustible material should there
be a room side-wall abutting the enclosure. The
opening must have two timber uprights spaced
710mm (between) at the front. The bearer rails on
the base of the outer steel cabinet will sit directly on
the floor. No insulation is needed on top of the floor
in the recess. (See Fig. 1).
Note: Increase the 735 dim. for elevated installations
4. The floor in front of the heater will not require a
hearth or any other heat protection, although a
hearth (floor protector) may be provided, if desired,
purely for aesthetic reasons.
5. The usual three nogs may be fixed at each side of
the enclosure. At the front the lowest nog must have
its lower face 735mm above the floor. Further nogs
can be fitted anywhere above this one.
6. Fix the cladding to the sides and front of the
framed-up enclosure. Conventional paper-faced
wall cladding will be satisfactory on all faces of the
enclosure, although a more appropriate material
(such as Tile and Slate underlay) may be preferable
where tiles etc. are to be fitted.
7. If a decorative finish (such as tiles or slate) is to be
applied to the face of the enclosure, this should be
done next. The decorative finish must extend down
to the top of the recess, but may stop short of the
sides of the recess provided that packing is fitted
between the uprights of the enclosure and the
flanges of the outer steel cabinet to bring the
flanges in line with the outer surface of the
decorative finish.
8. If a mantelshelf is being fitted, it must extend no
more than 200 mm, and its undersurface must be at
least 1060mm above the floor or at least 305mm
above the top of the fascia if the base of the heater
is raised above floor level. Please note that the

installations.
9. Penetrate the roofing material on the flue
centreline, following the instructions accompanying
the special Zero Clearance Flue Kit.
10.
IMPORTANT. Cover the entire open space
surrounding the flue heat shield (at ceiling level)
with wire netting with a mesh small enough to
prevent the entry of birds or vermin. This will avoid
the risk of a fire from nesting inside the enclosure.
Note: Increase the D dim. for elevated installations
11.Assemble the two sides, the base, the back and the
top of the outer steel cabinet. Fix the two heat
deflectors under the top of the outer cabinet with
their flanges up, thus forming a channel with the
front flange of the cabinet top. (See Fig. 3 and 4).
When assembling the sides to the base, fit a bearer
rail at each side to raise the base of the outer
cabinet 25mm above floor level. Slide the cabinet
into the constructed recess. Check that it is centred
between the front studs and that the cabinet is
‘squared up’. Secure the outer cabinet to the front
studs through the six holes in the front flanges of
the outer cabinet.
