It is best to frame your fi replace after it is positioned and
the vent system is installed. Use 2x4's and frame to local
building codes.
Note: In order to avoid the possibility of exposed insulation
or vapour barrier coming in contact with the fi replace body,
it is recommended that the walls of the fi replace enclosure
be "fi nished" (ie: drywall/sheetrock), as you would fi nish any
other outside wall of a home. This will ensure that clearance
to combustibles is maintained within the cavity.
To install the fi replace face fl ush with the fi nished wall, position
the framework to accommodate the thickness of the fi nished
wall. It is not necessary to install a hearth extension with this
fi replace system.
When roughing in the fireplace, raise the fireplace to
accommodate for the thickness of the fi nished fl oor materials,
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.

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 distance
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.
