COLD CLIMATE INSULATION
pp
)
pp
)
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
fl oor on which the appliance rests, if fl oor is
above ground level. Gas line holes and other
openings should be caulked or stuffed with
unfaced fi berglass insulation. If the fi replace
is being installed on a cement slab, in cold
climates, a sheet of plywood or other raised
platform can be placed underneath to prevent
conducting cold up into the room. It also helps to
sheetrock inside surfaces and tape for maximum
air tightness and caulk fi restops.
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 traffi c 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.

These direct vent appliances are uniquely
suited for installations requiring a utility shelf
positioned directly above the fi replace. Utility
shelves like these are commonly used for locating television sets and decorative plants. Be
aware that this is a heat producing appliance.
Objects placed above the unit are exposed to
elevated temperatures.
To provide for the lowest possible shelf surface
use the alternate rear vent outlet with attached
venting routed in a way to minimize obstructions
to the use of the space above the appliance. Do
not insulate the space between the appliance
and the area above it. See Figure 9. The mini-
mum height from the base of the appliance to
the underside of combustible materials used to
construct a utility shelf in this fashion is shown
in the Table in Figure 9.
The appliance should be mounted on a fully
supported base extending the full width and
depth of the unit. The appliance may be located
on or near conventional construction materials.
However, if installed on combustible materials,
such as carpeting, vinyl tile, etc., a metal or

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.
If the appliance is to be elevated above fl oor
level, a solid continuous platform must be
constructed.
Headers may be in direct contact with the
appliance top spacers but must not be supported by them or notched to fi t around them.
All construction above the appliance must be
self supporting. DO NOT use the appliance for
structural support.
The fi replace should be secured to the side framing
members using the unit's nailing fl anges - one top
and bottom on each side of the fi replace front. See
Figure 12. Use 8d nails or their equivalent.

Proper Sizing of Gas Line
Properly size and route the gas supply line
from the supply regulator to the area where
the appliance is to be installed per requirements outlined in the National Fuel Gas Code,
NFPA 54 - latest edition (USA) or B149 - latest
edition (Canada).
Never use galvanized or plastic pipe. Refer to
Table 9 for proper sizing of the gas supply line,
if black iron pipe is being used. Gas lines must
be routed, constructed and made of materials
that are in strict accordance with local codes
and regulations. We recommend that a qualifi ed individual such as a plumber or gas fi tter
be hired to correctly size and route the gas
supply line to the appliance. Installing a gas
supply line from the fuel supply to the appliance
involves numerous considerations of materials,
protection, sizing, locations, controls, pressure,
sediment, and more. Certainly no one unfamiliar
and unqualifi ed should attempt sizing or installing gas piping.

Notes:
• All appliances are factory-equipped with a

valve (see Figure 46 on Page 26 ).
• See Massachusetts Requirements on Page 4
for additional requirements for installations in
the state of Massachusetts in the USA.
• The gas supply line should Not be connected
to the appliance until Step 6 (Page 26).

• A pipe joint compound rated for gas should be
used on the threaded joints. Ensure propane
resistant compounds are used in propane
applications. Be very careful that the pipe
compound does not get inside the pipe.
• It is recommended to install a sediment trap
in the supply line as close as possible to the
appliance (see Figure 46). Appliances using
Propane should have a sediment trap at the
base of the tank.
• Check with local building offi cial for local code
requirements (i.e. are below grade penetrations
of the gas line allowed?, etc).
IMPORTANT: If propane is used, be aware that
if tank size is too small (i.e. under 100-lbs, if
this is the only gas appliance in the dwelling.
Ref. NPFA 58), there may be loss of pressure,
resulting in insuffi cient fuel delivery (which
can result in sooting, severe delayed ignition
or other malfunctions). Any damage resulting
from an improper installation, such as this, is
not covered under the limited warranty.
