MONTANA INSTALLATION INSTRUCTIONS
WARNING!
Do not apply combustible finishing materials over any part of the stainless face of this fireplace or a structure fire may
result. The fireplace front may only be covered with noncombustible materials such as ceramic tile, brick or stone. Do not
cover or block any cooling air slots. Do not cover any portion of the opening to the fireplace that would prevent the
installation of an authorized glass door.
Figure 6 - Sidewalls and Surrounds
4. Sidewalls/Surrounds
Adjacent combustible side walls must be
located a minimum of 12” from the
fireplace opening. See Figure 6. If you
are using a decorative surround
constructed of combustible material, it
must be located within the shaded area
defined in Figure 6. Short stub walls are
also acceptable if they are contained
within the shaded area.
CLEARANCES!
A minimum 1½” air clearance must be maintained
at the back and sides of the fireplace assembly ex-
cept at the nailing flange where the clearance is ½”.
Chimney sections at any level require a 2” minimum
air space clearance between the framing and chim-
ney section.
3. Frame the Fireplace
Figure 5 shows a typical framing (using 2 x 4 lumber) of the
fireplace, assuming combustible materials are used. All
required clearances to combustibles around the fireplace must
be adhered to. Any framing across the top of the fireplace
must be above the level of the top standoffs.
2. Construct an Outdoor Enclosure
This fireplace is intended to be installed outside the house. It may be installed against the outside wall of the house or as a
freestanding fireplace on your porch, patio, or in your yard.
When installing the outdoor fireplace against an outside wall, it must be enclosed to prevent impact damage to the outside of the
fireplace. Build the outside enclosure out of standard building materials, being careful to maintain the minimum air clearances
specified in these installation instructions.
When installing this fireplace as a freestanding fireplace on your porch, patio or in your yard, it must be enclosed to prevent impact
damage to the fireplace. However, the enclosure must not be finished on all four sides. The exterior of the enclosure may be
finished in a textured plywood, a wood clapboard siding, brick, or a cultured stone. Vinyl siding is not recommended for use on the
front of the fireplace due to the heat the fireplace produces. This can cause the vinyl siding to deteriorate.
