INSTALLATION / FRAMING
Do not build shelves or cupboards into the area
above the fireplace.
While the fireplace can be installed directly on the floor, a
non-combustible hearth extension is required in front of the
fireplace, that must not be built higher than the bottom of the
fireplace to avoid air flow blockage. It may therefore be advis-
able to build the fireplace on a raised platform. The minimum
distance between the edge of the fireplace and any adjacent
wall, at right angles to it, is 21 inches. A wall projecting at 45°
from the outer edge of the fireplace is allowed; projections into
this area are permitted. Do not install into any area having
a height less than 6 feet (ceiling to fireplace bottom, exclud-
ing hearth height).
See Section on Framing. The location
of windows, doors and the traffic flow in the room where the
stove is to be located should be considered. If possible, you
should choose a location where the chimney will pass through
the house without cutting a floor or roof joist.

Clearance from combustibles to furnace hot air duct work as
specified by the furnace manufacturer is satisfactory. No ad-
ditional clearances are required.

Note: In order to avoid
the possibility of exposed
insulation or vapour bar-
rier coming in contact
with the fireplace body,
it is recommended that
the walls of the fireplace
enclosure be “finished”
(ie: drywall/sheetrock),
as you would finish any
other outside wall of a
home. This will ensure
that clearance to com-
bustibles is maintained
within the cavity.

Clearances to finishing materials for framing: 6 3 /

" mini-
mum of
non-combustible material to the top of the unit
and a mini mum 3½" to either side. However we recom-
mend that 6 3 /
4
" of non-combustible material be used all
around.
Objects placed in front of the fireplace must be kept a
minimum of 48" away from the front face of the unit.
Non-combustible material (brick, stone, cement board or
ceramic tile) may protrude over the black painted
surface of
the fireplace front.
The fireplace should be framed using 2x4 lumber. Mobile
home installation requires the fireplace to be secured to
the floor. We recommend that the fireplace be secured
to the floor in all cases. use the pallet packing brackets
to accomplish this.
If ducting is to be installed, the minimum
enclosure ceiling height is 7 feet. Without ducting, the ceiling
height may be brought down to a minimum of 6 feet. However
a fireplace enclosure with a height less than 7 feet must be
provided with sufficient air circulation to avoid a fire hazard.
Install ventilation grilles (minimum openings of 40 sq. inches)
at both floor and ceiling levels of the enclosure. These grilles
must not restrict the flow of heat by more than 25%.
Do not place insulation into the enclosure around the
fireplace or the chimney. Combustible framing materials
may not be closer than 2 inch from the side of the unit
and 5 inches from the top of the unit.
