7. DO NOT use chimney cleaners or flame colorants in your fireplace.
8. The flue damper must be open at all times when the fireplace is in use.
9. While servicing this fireplace, always shut off any electricity or gas to the fireplace. This will prevent possible electric shock or
burns. Also, make sure the fireplace is completely cooled before servicing.

MONTANA INSTALLATION INSTRUCTIONS
D. PRE-INSTALLATION PREPARATION
1. Fireplace Locations and Space Requirements
This fireplace is intended for installation on an outdoor patio or in your yard. It must never be installed inside of the warm air
envelope of your structure. Significant cold air infiltration will result if it is installed inside of the structure. Figure 2 shows two
typical installations.
Figures 3 and 4 show two typical installations assuming an outside air kit is being used. Therefore, an allowance must be made for
90° bends. Less space is required when ducting goes directly outside without forming elbows.
Figure 2 - Fireplace Locations
Note: If the fireplace is a freestanding fireplace, it must
be located a minimum of 10 from a combustible structure.
A minimum height of 6 4 measured from the base of the
fireplace to the bottom of the termination cap is permitted in this installation.
These are rough framing dimensions only.
Æ
CLEARANCES!
A minimum 1½ air clearance must be maintained
at the back and sides of the fireplace assembly except 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 chimney section.
Figure 3 - Installation Along a Wall
or an Exterior Chase
Figure 4 - Corner Installation
WARNING!
To prevent contact with sagging or loose insulation, the fireplace must not be installed against vapor barriers
or exposed insulation. Localized overheating could occur and a fire could result.

MONTANA INSTALLATION INSTRUCTIONS
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.
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.
CLEARANCES!
A minimum 1½ air clearance must be maintained
at the back and sides of the fireplace assembly except at the nailing flange where the clearance is½.
Chimney sections at any level require a 2 minimum
air space clearance between the framing and chimney section.
Æ
Figure 5 - Framing the Fireplace
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.
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.
