Figure 3
FIREBOX CLEARANCES
The firebox may be placed directly on a combustible floor,
against a combustible wall at marked clearances, or on a
raised wooden platform.
If the firebox is to be installed on a raised wooden
platform, the platform must be a continuous level surface.
The firebox must be secured in place so it cannot shift
positions.
Only the header (see Figure 3) may rest on the standoffs
on top of the firebox.. When the firebox is installed over
carpeting, vinyl tile, or any combustible material other than
wood flooring, it must be installed on a metal or wood
panel extending its full width and depth. Alternatively, the
carpeting, vinyl tile, etc. may be removed beneath the
firebox before installing.
COMBUSTIBLE MATERIALS MUST NOT BE INSTALLED
OVER OR TOUCH ANY BLACK PAINTED SURFACE. DO
NOT BLOCK HEAT CIRCULATING AIR OUTLETS. DOING
SO MAY RESULT IN POTENTIAL FIRE HAZARDS
.
1. Sidewall Clearances: Clearances from the side of the
firebox opening to any adjacent combustible wall should
not be less than 7".
2. Ceiling Clearances: The ceiling height should
not be less than 42" from the top of the firebox
opening.
3. Front Clearances: 24” from the front of the
firebox opening to any combustible materials.
INSTALLING THE FIREBOX
This list of specific instructions will help you make certain that
every installation operation is performed correctly. Complete the
installation steps in the sequence shown.
LOCAL BUILDING CODES SHOULD BE CONSULTED IN
ALL CASES AS TO THE PARTICULAR REQUIREMENTS
CONCERNING THE INSTALLATION OF FACTORY
BUILT FIREBOXES. Select the location for the firebox by
taking into consideration the factors previously outlined in the
“Choosing the Location.” See page 5.
Framing the Firebox
The width of the framed opening must be 46 9/16". The height of
the framed opening must be 38 1/8". The entire firebox can be
elevated above the floor to achieve a raised hearth effect. This can
be done by adding a small platform to achieve the desired height.
NOTE: The wiring for the optional blower must be installed
during the framing stage.
When the framing is inside, the outside wall will be insulated. If
the framing or chase is outside, thin insulation should be used in
the framing on the back, sides, and top. The bottom should be
insulated with a hard insulating board. This will prevent cold from
going into the chase through the firebox to the living space.
Install the Firebox
Install the firebox into the framed opening by placing it directly in
front of the opening and sliding it into the proper position.
Level the Firebox
Check the level of the firebox on the top edge of the firebox face.
Shim if necessary.
Secure the Firebox
Secure the firebox to the framing. The nailing flange on the
firebox will make securing the firebox to the frame quick and easy.
Use appropriate size nails or screws to secure the firebox.
