Firebox Framing
Construct firebox framing following Figures 6
through 8 and the chart on page 8 for your
specific installation requirements. Refer to
Figures 4 and 5 on pages 6 and 7 for firebox
dimensions.
The firebox may be installed directly on a com-
bustible floor or raised on a platform of an
appropriate
height. Do not place firebox on
carpeting, vinyl or other soft floor coverings. It
may, however, be placed on flat wood, ply-
wood, particle board, metal or other hard sur-
faces which extend the full width and depth of
the enclosure. Be sure firebox rests on a solid
continuous floor or platform with appropriate
framing for support and so that no cold air can
enter room from under the firebox.
The firebox may be positioned and then the
framing built around it, or the framing may be
constructed and the firebox positioned into the
opening.
Usually, no special floor support is needed for
the firebox, however, to be certain:
1. Estimate the total weight of the firebox
system and surround materials such as marble,
brick, stone, etc., to be installed.
2. Measure the square footage of the floor
space to be occupied by the system and sur-
rounds.
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.
4. Use this information and consult your local
building code to determine if you need addi-
tional support.
CAUTION: DO NOT BLOCK THE HEAT-CIRCU-
LATING AIR INLETS AND OUTLETS ON THE
VFC AND VFCE MODELS. DOING SO MAY
CREATE A POTENTIAL FIRE HAZARD.
If you plan to raise the firebox, build the plat-
form assembly then position firebox on top.
Secure the platform to the floor to prevent
possible shifting.
