INSTALLATION TYPES
This fire can be fitted against an outside facing facing flat wall surface or into a
fireplace opening cut into the wall.
When fitting the fire in front of the inner cavity wall, the distance between the
mounting face of the fire and the rear face of the firebox must be a minimum of
170mm, a false chimney breast or fireplace surround should be constructed. The
firebox must then be secured into the fireplace using the method described in
section 2. Any combustible material must be removed from the the area around
the firebox flange. In all installations, ensure that there is no structural damage to
the property or the damp course. See fig. 4 below
When fitting the fire into a cavity wall, this requires the opening of the inner leaf
of brickwork, to recess the firebox into. The opening needs to be sufficient to
accomodate the firebox. To support the wall above the hole, a suitable lintel must
be inserted across the top of the opening. If fitting the appliance into a cavity wall,
a lintel 750mm long having a thickness of 75mm with a height of the inner wall
should be used. The lintel could be either pre-cast concrete or steel - Catnic
CN52 or CN 46 could be used, depending upon the inner wall thickness. Before
proceeding with the installation of the fire, an assessment of the area immediately
above the fire is required, see Fig. 5 overpage. If there is no existing openings
within either triangle, proceed with forming the opening. However, if opening or
beams occur within either triangle, then you should seek specialist advice from a
structural engineer or consider relocating the proposed position of the firebox.
