operation. External electrical power (110 vac)
is recommended to operate these units. If the
system operates on line voltage with 6V fan
control module, four (4) "AA" batteries can be
used as a backup in case of a power outage. The
electronic appliance can be operated without a
fan, solely with four (4) "AA" batteries.

These vented gas fireplace heaters are sealed
combustion, air-circulating gas fireplaces de­signed for residential applications.

Approved Vent Components - These fireplaces
are designed, tested and listed for operation
and installation with, the following vent com­ponents only:

NEW YORK CITY, NEW YORK (MEA)

Installation of these fireplaces are approved
for installation in New York City in the US state
of New York.

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.

Note: 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.

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.

MANUFACTURED HOME

Appliance And Vent Clearances

The appliance is approved with zero clearance to combustible materials on
all sides (as detailed in Table 6 ), 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 2).

*Note: 3 in. (76 mm) above any horizontal/inclined vent component.

**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.

Hearth Extension - A hearth extension is not required with this appliance.

If a hearth extension is used, do not block the lower control compartment
door. Any hearth extension used is for appearance only and does not have
to conform to standard hearth extension installation requirements.

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 7). 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 7.

Wall Finishes / Surrounds / Mantels

Note: Combustible wall finish materials and/or surround materials
must not be allowed to en-croach 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 face (see
Figure 9 and Figure 50 on Page 34).

Non-combustible materials, such as surrounds and other appliance trim,
may be installed on the appliance face with these exceptions: they must
not cover any portion of the removable glass panel.

Vertical installation clearances to combustible mantels vary accord­ing to the depth of the mantel. See Figure 8. Mantels constructed of
non-combustible materials may be installed at any height above the
appliance opening; however, do not allow anything to hang below the
fireplace hood.
