Air supply duct must be fitted
to bring cool air into the stove.
This could be through an external
wall, from another room, or
from the same room as the stove.
PREPARATION OF FIREPLACE
If the fireplace contains combustible materials, inlet and outlet air
vents with an area of 246cm² each must be fitted below and above
the stove convection case to provide a continual air flow around the
stove. It is recommended that Calcium Silicate board is used
(130mm board, with a 100mm air gap between the stove and the
insulation (see Fig. 12).
If the fireplace does not contain combustible materials, it is still
recommended to have a layer of insulation or ventilate the space
between the casing and the outer wall. The insulation may consist of
a layer of mineral fibre or calcium silicate board. Insert this into the
opening before sliding in the convection casing.
The air supply inlet can be fitted in the room or outside, in
accordance with the requirements in 'Air Supply' section (p11). The
inlet grille must not constrict the airflow through the duct and it
must be permanently open. A semi rigid aluminium flexible duct of
no less than 80mm diameter is used to bring the air to the stove .
The duct must be less than 5.5m long, have no more than five 90º
bends and two 45º elbows. The 80mm diameter spigot, provided
with the stove should be fitted on the outside of the convection case,
using two self tapping screws and the duct should be terminated on
the spigot with a jubilee clip. The 100mm diameter spigot provided
should be fitted to the inside of the convection case using two nuts
on the outside and the self adhesive foam should be glued into
position around the circumference of the inside of the 80mm spigot
in order to seal against the spigot on the back of the stove when it is
installed.
Before fitting the appliance into an existing fireplace remove the
fireback and any loose in-fill material.
The surround and opening for the appliance must conform with
Fig.11. The flat area around the opening should be a minimum of
500mm wide and 600mm high. Ensure that the hearth and the base
in the opening are flat, level, and at right angles to the surround.
