22 LT5052 (ISS 5)
CLEARANCE TO SHELF
Minimum clearance from hearth to
underside of combustible shelf should be
650mm provided shelf depth 125mm or
less. When the shelf depth is increased by
increments of 12.5 mm greater than
125mm, add 25mm to the 650mm
minimum clearance.
CLEARANCE TO SIDES OF FIRE
Minimum width between vertical sides of
combustible surround should not be less
than 700 mm provided fire is central to
surround and sides do not project more
than 150 mm. When vertical side forward
projection is increased by 12.5 mm add
50 mm to inside width of surround.
NOTE: When fire is fitted this provides a
minimum side clearance of 100mm.
SECTION NINE To Install the Appliance (installation instructions)
INSTALLING THE FIRE BOX
Check that the proposed site conforms to the specifications as previously stated.
Cut opening into cavity (fig. 3) and lay down the hearth of non-combustible material centrally about the proposed
centre line of the appliance taking care to protect the hearth surface against scratching.
NOTE: If necessary a lintel
should be fitted to support
the brickwork. The opening in
the cavity around the
appliance should be suitably
sealed to prevent ingress of
gases using a non-porous
material (i.e. rockwool). Use
the length of foam to seal
around the flange of the fire
and the back panel.
The floor of the recess should
then be screeded to the
hearth level to allow for
accurate positioning of the
firebox and flue spigot.
