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 gal. capacity.
3. If you smell gas
• 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 neighbor’s
phone. Follow the gas supplier’s instructions.

It is best to build rebox framing the appliance is set in place. Refer to the dimensions for
your replace on Page 7. 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 appropri-
ate height. Do not place rebox on carpeting, vinyl, or other soft oor coverings. It may, however,
be placed on a at wood, plywood, particle board, or other hard surfaces. Be sure rebox rests on
a solid continuous oor or platform with appropriate framing for support. No cold air should enter
room from under the rebox.

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-painted face of the appliance. A 300°F
minimum adhesive may be used to attach facing materi-
als 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. Combustibles may come to the top and side
edges but not overlay the face.
This gas replace should be installed by a qualied installer
in accordance with local building codes and with current
CSA-B149 (.1 or .2) Installation codes for Gas Burning
Fireplaces and Equipment. If the unit is being installed in a
mobile home the installation should comply with the current
CAN/CSA Z 240 .4 code.
FOR U.S.A. Installations follow local codes and/or the cur-
rent National Fuel Gas Code. ANSI Z223.1.

1. This replace gives off high temperatures and should
be located out of high trafc areas and away from
furniture and draperies.
2. Children and adults should be alerted to the hazards
of the high surface temperatures of this replace and
should stay away to avoid burns or ignition of cloth-
ing.
3. Caution, due to high glass surface temperature children
should be carefully supervised when they are in the
same room as the replace.
4. Under no circumstances should this replace be modi-
ed. Parts removed for servicing should be replaced
prior to operating the replace again.
5. Installation and any repairs to this replace should
be carried out by a qualied service person. A profes-
sional service person should be contacted to inspect
this replace annually. Make it a practice to have all of
your gas replaces checked annually. More frequent
cleaning may be required due to excess lint and dust
from carpeting, bedding material, etc.
6. Control compartments, burners and air passages in this
replace should be kept clean and free of dust and lint.
Make sure that the gas valve and pilot light are turned
off before you attempt to clean this replace.
7. The venting system (chimney) of this replace should
be checked at least once a year and if needed your
venting system should be cleaned.
8. Keep the area around your replace clear of combus-
tible materials, gasoline and other ammable vapor and
liquids. This replace should not be used as a drying
rack for clothing, nor should Christmas stockings or
decorations be hung on or around the replace.
9. Under no circumstances should any solid fuels (wood,
coal, paper or cardboard etc.) be used in this re-
place.
10. The ow of combustion and ventilation air must not be
obstructed in any way.
11. When the replace is installed directly on carpeting,
vinyl tile or any combustible material other than wood,
the replace must be installed on a metal or wood panel
extending the full width and depth of the replace.
12. This replace requires adequate ventilation and com-
bustion air to operate properly.
13. This replace must not be connected to a chimney ue
serving a separate solid fuel burning replace.
14. When the replace is not in use it is recommended that
the gas control valve be left in the “OFF” position.
This appliance has been approved for after-market
mobile home installations.
IMPORTANT:
PLEASE READ THE FOLLOWING CAREFULLY
Remove any plastic from trim parts before turning the
replace ON.
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 your Monessen gas replace to give
off some odor the rst time it is burned. This is due to the
curing of the paint and any undetected oil from the manu-
facturing process.
Please ensure that your room is well ventilated — open
all windows.
It is recommended that you burn your Monessen replace
for a least ten (10) hours the rst time you use it. If the
optional fan kit has been installed, place the fan switch
in the “OFF” position during this time.
