COLD CLIMATE INSULATION
For cold climate installations, seal all cracks
around the appliance with noncombustible
material and wherever cold air could enter
the room. It is especially important to insulate
outside chase cavity between studs and under
floor on which the appliance rests, if floor is
above ground level. Gas line holes and other
openings should be caulked or stuffed with
unfaced fiberglass insulation. If the fireplace
is being installed on a cement slab, in cold
climates, a sheet of plywood or other raised
platform can be placed underneath to prevent
conductingcoldupintotheroom.Italsohelpsto

LOCATION
In selecting the location, the aesthetic and
functional use of the appliance are primary
concerns. However, vent system routing to
the exterior and access to the fuel supply are
also important. Consideration should be given
to traffic ways, furniture, draperies, etc., due
to elevated surface temperatures (Figure 4 ).
The location should also be free of electrical,
plumbing or other heating/air conditioning
ducting.

to be positioned in front of or overlapping the appliance front face. See Figure 58 on Page 32.
Non-combustible materials, such as surrounds and other appliance trim, may be installed on the
appliance front face with these exceptions: they must not cover any portion of the removable glass
panel or louvers.

To The Framing
Note: The nailing flanges, combustible members
and screw heads located in areas directly adjacent
to the nailing flanges, are EXEMPT from the 1/2”
clearance to combustible requirements for the
firebox outer wrapper. Combustible framing may be
in direct contact with the nailing flanges and may
be located closer than 1/2” from screw heads and
the firebox wrapper in areas adjacent to the nailing
flanges. Frame the opening to the exact dimensions
specified in the framing details of this manual.

Step 1. FRAMING
Frame these appliances as illustrated in Figure
14 on Page 11, unless the appliance is to be
installed in a corner. See Figure 15 on Page
12 for corner framing installations. All framing
details must allow for a minimum clearance to
combustible framing members as shown in
Table 8 on Page 9.
STEP 2. ROUTING GAS LINE
Remove Cardboard Before
Using Appliance
Route a 1/2" (13 mm) gas line along the inside
of the right side framing as shown in Tables.
Gaslinesmustberouted,constructedandmade
of materials that are in strict accordance with
local codes and regulations. All appliances are
factory-equipped with a flexible gas line con-
nector and 1/2 inch shutoff valve. (See Step 6
on Page 26).
See-Through Model Shown
Figure 11
If the appliance is to be elevated above floor
level, a solid continuous platform must be
constructed.
TYPICAL INSTALLATION SEQUENCE
The typical sequence of installation follows,
however, each installation is unique resulting
in variations to those described.
Headers may be in direct contact with the
appliance top spacers but must not be sup-
ported by them or notched to fit around them.
All construction above the appliance must be
self supporting. DO NOT use the appliance for
structural support.
