FRAMING AND INSTALLING THE FIREPLACE 

 
STEP 1: Frame the opening for the fireplace using the 
dimensions shown in figures 1 & 2. 
STEP 2: If the fireplace is to be installed directly on carpeting, 
tile (other than ceramic), or any combustible material other 
than wood flooring, the fireplace must be installed upon a 
metal or wood panel extending the full width and depth of the 
fireplace. 
STEP 3:  Set the fireplace directly in front of this opening and 
slide the unit back until the nailing flanges touch the side 
framing. 
STEP 4: Check the level of the fireplace and shim with sheet 
metal if necessary.  Make sure the unit is balanced on each 
side. 
STEP 5: Before securing fireplace to prepared framing, the 
ember protector (provided), must be placed between the hearth 
extension (not supplied), and under the bottom front edge of 
the fireplace to protect against glowing embers falling 
through.  If the fireplace is to be installed on a raised platform, 
a Z-type ember protector (not supplied) must be fabricated to 
fit your required platform height.  The ember protector should 
extend under the fireplace a minimum of 1 - 1/2”.  The ember 
protector should be made of galvanized sheet metal (28-gage 
minimum).  
STEP 6: Using screws or nails, secure the fireplace to the 
framing through flanges located on the sides of the fireplace.  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

HEARTH EXTENSION 

A hearth extension projecting a minimum of 16” in front of 
and a minimum of 8” beyond each side of the fireplace 
opening is required to protect combustible floor construction 
in front of the fireplace.  Fabricate a hearth extension using a 
material which meets the following specifications: a layer of 
non-combustible, inorganic material having a thermal 
conductivity of K = 0.84 BTU IN/FT. HR. F (or less) at 1” 
thick.  For example, if the material selected has a K factor of 
0.25, such as glass fiber, the following formula would apply: 
 
 
 
 
 
Thermal conductivity “K” of materials can be obtained from 
the manufacturer or supplier of the non-combustible material.  
 If the hearth extension is to be covered, use non-combustible 
material such as tile, slate, brick, concrete, metal, glass, 
marble, stone etc.  Provide a means to prevent the hearth 
extension from shifting and seal gap between the fireplace 
frame and hearth extension with a non-combustible material 
(see figure 3). 
 
 
 
 
 
 
 
 
 
 
 
 
 

 
 
OPTIONAL OUTSIDE AIR KIT (MODEL AK4 / AK4F) 

The installation of an outside air kit should be performed 
during the rough framing of the fireplace due to the nature of 
its location.  Outside combustion air is accessed through a 
vented crawl space (AK4F) or through a sidewall (AK4).  See  
page 10, figure 23 for instructions on how to operate the air 
kit. 
 

WARNING

 Hearth extension is to be installed only
