1. This installation is for use with a fire surround
or false chimney breast having a minimum depth
of 140mm (5 1/2in.). The flue length may be cut
to suit the wall thickness. (See prepare flue
assembly section) Combustible material within a
false chimney breast must be at least 75mm from
the fire box.
2. The non-combustible hearth must project at
least 300mm in front of the convection box front
flanges and be at least 625mm wide (Figures 1 &
8).
3. The cavity should be sealed where the flue tube
hole has been cut. We recommend filling fully
across the cavity with Rockwool or equivalent to
at least 100mm around the opening (See figure 12)
7.3 Brick, stone etc. building. Main case
recessed into wall.
(Figure 9)
1. This installation has the fire box recessed into
the inner wall of the building. The front flanges
of the fire box and the appliance fascia will abut
the front surface of the wall.
2. The non-combustible hearth must project at
least 300mm in front of the convection box
front flanges and be at least 625mm wide
(Figure 1).
The recess in the inner wall for the fire box
should be to the size shown in figure 1. The
bottom of this recess should be at the same level
as the top surface of the hearth.
A lintel may be required above the recess for the
fire box. If in doubt, seek expert building advice
before commencing to cut the recess.
Whenever a lintel is required to support the
recess in the inner leaf of a brick/blockwork building, refer to the following section (See
figures 10 and 11).
