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 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 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.

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 3).

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 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 fireplace. Utility
shelves like these are commonly used for locat­ing television sets and decorative plants.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Top View

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

on Page 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 on Page 8.

The appliance should be mounted on a fully
supported base extending the full width and

COMBUSTIBLES
Appliance And Vent Clearances

The appliance is approved with zero clearance to com­bustible materials on all sides (as detailed in Table 5),
with the following exception: When the unit is installed

with one side flush with a wall, the wall on the other
side of the unit must not extend beyond the front edge
of the unit. In addition, when the unit is recessed, the

side walls surrounding the unit must not extend beyond
the front edge of the unit (see Figure 3).

** Note: See Page 9, Step 1 for clearance requirements

to the nailing flange located at each side of the unit and
any screw heads adjacent to it.

*** Note: To ensure proper fit of the facade (required - sold

separately). The appliance base will need to be elevated
3/4" minimum above the floor to allow for the proper
fit of the facade (i.e. use 3/4" board as platform).

Shelf Height

To provide for the lowest possible shelf surface, the
venting attached to the top vent should be routed in a
way to minimize obstructions to the space above the
appliance. 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 the table in Figure 8.

Wall Finishes / Surrounds / Mantels

Note: Combustible wall finish materials and/or surround
materials must not be allowed to encroach the area defined
by the appliance front face (black sheet metal). Never al­low combustible materials to be positioned in front of or
overlapping the appliance front face.

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 glass or the air gaps above the glass door.

Vertical installation clearances to combustible mantels
vary according to the depth of the mantel. Mantels
constructed of non-combustible materials may be
installed above the appliance opening as outlined in

Figure 9.

NOTE: We recommend the use of high temperature

paint (rated 175° F or higher) on the underside of the
mantel.

and components installed and pre-wired.

1. Remove the shipping carton, exposing the
front glass door.

TYPICAL INSTALLATION SEQUENCE

The typical sequence of installation is outlined
below. However, each installation is unique
and may result in variations to the steps
described.

See the page numbers references in the follow­ing steps for detailed procedures.

Step 1. (Page 9) Construct the appliance

framing. Position the appliance within
the framing and secure with nailing
brackets.

Step 2. (Page 12) Route gas supply line to

appliance location.

Step 3. (Page 13) Install the vent system and

exterior termination.

Step 4. (Page 23) Field Wiring

Vac electrical power to the appliance
receptacle.

Step 5. (Page 24) Install blower kit (optional

equipment).

Step 6. (Page 24) Make connection to gas

supply.

Step 7. (Page 25) Verify appliance opera-

tion.

Step 1. FRAMING

Frame these appliances as illustrated in Figures
12 and 14 on Pages 10 and 12 (Figure 14

applies to corner framing installations only).
All framing details must allow for a minimum
clearance to combustible framing members as
shown in Table 5 on Page 8.

If the appliance is to be elevated above floor
level, a solid continuous platform must be
constructed below the appliance.

Headers may be in direct contact with the
appliance top spacers but must not be sup­ported 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.

The fireplace should be secured to the side fram­ing members using the unit's nailing flanges
each side of the fireplace front (see Figure 11).
Use 8d nails or their equivalent.
