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.
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 neigh-
bor’s phone. Follow the gas supplier’s instruc-
tions.

Firebox framing can be built before or after the appliance
is set in place. Refer to Figure 2 for replace and framing
dimensions. The framing headers may rest on the top of
the rebox standoffs. Do not bring headers below top of
standoffs.  When planning your framing and instal-
lation, keep in mind that both the gas line and electricity
should come in on the right side of the rebox (as you are
facing the front of the replace).
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.

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. See Figure 4 for sug-
gested 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. Refer to the
National Fuel Gas Code ANSI Z233.1/NFPA 54 — (cur-
rent edition), the Uniform Mechanical Code — (current
edition), and Local Building Codes for specic installa-
tion requirements.
• These units can be installed in a bathroom.
