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. 
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 40 7/8".  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.
