PRE-INSTALLATION NOTES
The fireplace may be installed directly on a
combustible floor or raised on a platform of an
appropriate height. Do not place fireplace on
carpeting, vinyl or other soft floor coverings. It
may, however, be placed on flat wood, ply-
wood, particle board or other hard surfaces. Be
sure fireplace rests on a solid continuous floor
or platform with appropriate framing for sup-
port and so that no cold air can enter the room
from under the fireplace.
The fireplace may be positioned and then the
framing built around it, or the framing may be
constructed and the fireplace positioned into
the opening.
Usually, no special floor support is needed for
the fireplace, however, to be certain:
1. Estimate the total weight of the fireplace
system and surround materials such as brick,
stone, etc., to be installed.
2. Measure the square footage of the floor
space to be occupied by the system, surrounds
and hearth extensions.
3. Note the floor construction, i.e. 2 x 6’s, 2 x
8’s or 2 x 10’s, single or double joists, type and
thickness of floor boards.
Note: All framing dimensions calcu-
lated for 1/2" dry wall at the appliance
face. If sheathing the chase or finish-
ing with other thickness materials, cal-
culations will need to be made.
