Combustion protrusions such as mantels and shelves may occur at or after a minimum distance of 2" away
from the side of the fi replace. Thereafter, the depth of any protrusions must be equal to or less than the dis-
tance from the side of the fi replace up to a depth of 6", after which no greater clearance than 6" is required.
This can be considered a side wall with no length boundary.

BGD36 FRAMING

In order to avoid the possibility of exposed insulation or vapour barrier coming in contact with the
appliance body, it is recommended that the walls of the appliance enclosure be "finished" (ie:
drywall / sheetrock), as you would finish any other outside wall of a home. This will ensure that
Do not notch the framing around the appliance stand-offs. Failure to maintain air space clearance
may cause over heating and fire. Prevent contact with sagging or loose insulation or framing and
other combustible materials. Block opening into the chase to prevent entry of blown-in insulation.
When constructing the enclosure allow for finishing material thickness to maintain clearances.
Framing or finishing material closer than the minimums listed must be constructed entirely of
non-combustible materials. Materials consisting entirely of steel, iron, brick, tile, concrete, slate,
glass or plasters, or any combination thereof are suitable. Materials that are reported as passing
ASTM E 136, Standard Test Method for Behaviour of Materials in a Vertical Tube Furnace at 750°C
It is best to frame your fi replace after it is positioned and the vent system is installed. Frame to local building
codes.
It is not necessary to install a hearth extension with this fi replace system.
When roughing in the fi replace, raise the fi replace to accommodate for the thickness of the fi nished fl oor mate-
rials, i.e. tile, carpeting, hard wood, which if not planned for will interfere with the opening of the lower access
door and the installation of many decorative fl ashing accessories.
Combustible materials may be installed fl ush with the front of the fi replace but must not cover any of the black
face-areas of the fi replace. Non-combustible material (brick, stone or ceramic tile) may protrude in these areas.
