COLD CLIMATE INSULATION

For cold climate installations, seal all cracks
around your 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 appliance rests, if floor is above
ground level. Gas line holes and other open-
ings 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 conduction of cold transferring to
the fireplace and into the room. It also helps to
sheetrock inside surfaces and tape for maximum
air tightness and caulk firestops.

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.
Due to high temperatures, the appliance
should be located out of traffic and away from
furniture and draperies (Figure 2).
En raison des températures élevées,
l'appareil devrait être installé dans un
endroit où il y a peu de circulation et loin
du mobilier et des tentures (Figure 2).
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 fireplace. Util-
ity shelves like these are commonly used for
locating television sets and decorative plants.

Be aware that this is a heat producing ap-
pliance. Objects placed above the unit are
exposed to elevated temperatures.
Do not insulate the space between the ap-
pliance and the area above it (see Figure 7).
The minimum height from the base of the appli-
ance to the underside of combustible materials
used to construct a utility shelf in this fashion
is shown in Figure 7.
The appliance must be mounted on a fully sup-
ported 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 or other combustible material
other than wood flooring, the appliance shall be
installed on a metal or wood panel extending the
full width and depth of the appliance.
