A hearth extension in front of heater is recommended 
but not required. 

Planning the installation is an important first step: it will 
save time and money later in the actual installation. In 
planning the installation, consider:

  1.  Where the heater will be located. 
  2.  All components needed to complete the   

  project. 

The heater should only be mounted on the following 
surfaces:

•  A flat combustible (burnable) surface.
•  A raised wooden platform.
•  A concrete block or other solid object placed be-

neath each of the four corners  of the heater.

To mount the heater:
1. Choose unit location.
2. Place unit in position and secure to floor with 1¹⁄₂" 

screws, or nails. The holes to secure the unit to the 
floor are located just behind the bottom louvre on the 
left and right hand side of the unit.

3. Frame in heater with a header across the top.  It is 

important to allow for finished face when setting the 
depth of the frame. 

4. Attach heater to frame using adjustable frame drywall 

strips (located behind access door for shipping).  Preset 
depth to suit facing material (adjustable to 1/2" , 5/8" or 
3/4" depths). (Fig. 4)

5. Use existing screws in side of unit to attach drywall 

strip. Measure from face of heater to face of drywall 
strip to determine final depth. (Fig. 4)

Framing can take place before or after the heater is set 
in place.  The framing should be positioned to accom-
modate the wall covering and facing material. Framing 
material should be 2x4 or heavier.  Framing headers 
may rest on top of heater.  (Refer to Page 4, Figures 1 
and 2 for heater and framing dimensions.)

When a heater is installed in a chase or an outside wall, 
the enclosure should be insulated like any other wall 
of the home.  Insulation should be installed under the 
heater and on the inside of the exterior walls. (Fig. 5)  
NOTE: Insulating for cold climates is strictly a recom-
mendation and not a requirement.

Depending on the width of the mantel it may be in-
stalled higher or lower from the combustion chamber 
opening.  This also applies to the distance between the 
mantel leg (if installed) and the fireplace. Refer to Fig-
ures 3a and 3b for correct mounting heights and widths 
for combustible mantels and mantel legs. 
Noncombustible mantels and legs may be installed at 
any height above the appliance opening.
