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.

Read this homeowner manual thoroughly and follow all
instructions carefully. Inspect all contents for shipping
damage and immediately inform your dealer if any damage
is found. Do not install any unit with damaged, incomplete,
or substitute parts. Check your packing list to verify that
all listed parts have been received. You should have the
following:
• Fireplace (Firebox and Burner System)
• Reective Glass

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 your gas line can come in on the
right or left side of the rebox (as you are facing it) and
your electricity will come in on the right side.
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 as a room divider or an
island. See Figure 3 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 openings 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.

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
nailing anges are 1/2" or 5/8" to accommodate different

: 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. It is
permissible to bring combustible wall board to the top of
the standoffs on the top and to the wall board stand-offs
on the sides of the unit. 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.
 Fireplace may be installed on top of framing or

not protrude beyond the face.

Consult local building codes before beginning
the installation. The installer must make sure to
select the proper vent system for installation. The
approved 5 x 8 venting components are Simpson
Duravent and Selkirk products listed on Page 49.
UL1777 exible venting is also approved for use
on these models. Before installing vent kit, the
installer must read this replace manual and
vent kit instructions.
Only a qualified installer/service person
should install venting system. The installer
must follow these safety rules:
• Wear gloves and safety glasses for protec-
tion.
• Use extreme caution when using ladders
or when on rooftops.
• Be aware of electrical wiring locations in
walls and ceilings.
The following actions will void the warranty on your vent-
ing system:
• Installation of any damaged venting component.
• Unauthorized modication of the venting system.
• Installation of any component part not manufactured
or approved by Vermont Castings Group.
• Installation other than permitted by these instruc-
tions.
