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.
CAUTION: Due to high temperatures, the ap-
pliance should be located out of traffic and
away from furniture and draperies
(Figure 2).
AVERTISSEMENT : En raison des tem-
pératures 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 also should 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 above the fireplace. Utility shelves like
these are commonly used for locating television
sets and decorative plants.
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 on Page 11
.
Be aware that this is a heat-producing ap-
pliance. Objects placed above the unit are
exposed to elevated temperatures.
COLD CLIMATE INSULATION
For cold climate installations, seal all cracks
around the appliance with noncombustible
material and wherever cold air could enter the
room. If the floor is above ground level, it is
especially important to insulate outside chase
cavity between studs and under the floor on
which the appliance rests. 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 under-
neath to prevent cold transfer to the fireplace
and into the room. It also helps to sheetrock
inside surfaces and tape for maximum air
tightness and caulk firestops.
Top of Fireplace
Opening
Drywall
When unit is installed with one
side flush with a wall, the wall
on other side of unit must not
extend beyond front edge of unit.
Do not insulate the space between the appli-
ance and the area above it
.
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 or vinyl tile), a metal or wood
barrier covering the entire bottom surface must
be used.
