monoxide poisoning are similar to the u with headaches,
dizziness and/or nausea. If you have these signs, the re-
place may not have been installed properly. Get fresh air
at once! Have the replace inspected and serviced by a
qualied service person. Some people are more affected
by carbon monoxide than others. These include pregnant
women, people with heart or lung disease or anemia,
those under the inuence of alcohol, and those at high
altitudes.
Propane/LP gas and natural gas are both odorless. An
odor-making agent is added to each of these gases. The
odor helps you detect a gas leak. However, the odor added
to these gases can fade. Gas may be present even though
no odor exists.
Make certain you read and understand all warnings. Keep
this manual for reference. It is your guide to safe and proper
operation of this replace.
1. This appliance is only for use with the type of gas
indicated on the rating plate. This appliance is not
convertible for use with other gases unless a certied
kit is used.
2. For propane/LP replace, do not place propane/LP
supply tank(s) inside any structure. Locate propane/
LP supply tank(s) outdoors. To prevent performance
problems, do not use propane/LP fuel tank of less than
100 lbs. capacity.

• shut off gas supply.
• do not try to light any appliance.
• do not touch any electrical switch; do not use any
phone in your building .
• immediately call your gas supplier from a neigh-
bor’s phone. Follow the gas supplier’s instruc-
tions.

It is normal for replaces fabricated of steel
to give off some expansion and/or contraction
noises during the start up or cool down cycle.
Similar noises are found with your furnace heat
exchanger or car engine.

It is not unusual for gas replace to give off
some odor the rst time it is burned. This is due
to the manufacturing process.

Firebox framing can be built before or after the appliance
is set in place. Construct rebox framing following Figure
2 or 3. The framing headers may rest on the top of the
rebox standoffs.
The rebox may be installed directly on a combustible oor
or raised on a platform of an appropriate height. When
the rebox is installed directly on carpeting, tile, or other
combustible material, other than wood ooring, the rebox
shall be installed on a metal or wood panel extending the
full width and depth of the enclosure.
To access control door, build a platform to make the
bottom of appliance equal to or higher than top of nished
hearth extension, or elevate unit a minimum of 7/8" above
suboor.

Plan for the installation of your appliance. This includes
determining where the unit is to be installed, the vent con-
guration to be used, framing and nishing details, and
whether any optional accessories (i.e. blower, wall switch,
or remote control) are desired. Consult your local building
code agency to ensure compliance with local codes, includ-
ing permits and inspections.
The following factors should be taken into consideration:
• Clearance to side-wall, ceiling, woodwork, and windows.

• This replace may be installed along a wall, across a
corner, or use an exterior chase. Refer to Figure 4 for
suggested locations.
• Location should be out of high trafc areas and away
from furniture and draperies due to heat from appli-
ance.
• Never obstruct the front opening of the replace.
• Do  install in the vicinity where gasoline or other
ammable liquids may be stored.
• Vent pipe routing. See VENTING section found in this
manual for allowable venting congurations.
• These units can be installed in a bedroom. See National
Fuel Gas Code ANSI Z233.1/NFPA 54 — (current
edition), the Uniform Mechanical Code — (current edi-
tion), and Local Building Codes for specic installation
requirements.

The replace must be installed on a non-combustible hearth
extending a minimum of 12" from the replace opening
(local codes may require a larger hearth). The hearth must
also extend to both sides of the face (see the table above
for the exact width of the face).

The replace must be secured to the oor and/or to framing studs as shown in Figure 6. Use two
(2) wood screws or masonry/ concrete screws to secure replace to the oor. Use four (4) screws
to attach replace to framing. The side brackets are adjustable from 1/2" to 5/8" to accommodate
different thickness of noncombustible material.

 Any remote wiring (i.e. remote control, wall switch, and optional fan) must be done prior to
nal nishing to avoid costly reconstruction.
Only noncombustible materials (i.e. brick, tile, slate, steel, or other materials with a UL re rating
of Zero) may be used to cover the black surface of the appliance. A 300°F minimum adhesive may
be used to attach facing materials to the black surface. If joints between the nished wall and the
replace surround are sealed, a 300°F minimum sealant material (General Electric RTV103 or
equivalent) must be used.
