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 fl oor on which 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 conduction
of cold transferring to the fi replace and 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.
Due to high temperatures, the appliance
should be located out of traffi c and away
from furniture and draperies (Figure 3).
En raison des températures élevées,
l'appareil devrait être installé dans
un endroit où il y a peu de circula-
tion et loin du mobilier et des tentures
(Figure 3).
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.
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

(Top Vent Application) (Top Vent Application)
Be aware that this is a heat producing
appliance. Objects placed above the unit
are exposed to elevated temperatures.
Do not insulate the space between the
appliance and the area above it (see
Figure 8).
The minimum 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 Figure 8.
The appliance must 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 or other combustible material other
than wood fl ooring, the appliance shall be
installed on a metal or wood panel extending
the full width and depth of the appliance.
