This fireplace is a vented product. This fireplace must be
properly installed by a qualified service person. The glass
door must be properly seated and sealed. If this unit is not
properly installed by a qualified service person with glass
door properly seated and sealed, combustion leakage
can occur.
 Early signs of carbon
monoxide poisoning are similar to the flu with headaches,
dizziness and/or nausea. If you have these signs, the fire-
place may not have been installed properly. Get fresh air
at once! Have the fireplace inspected and serviced by a
qualified 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 influence 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 fireplace.
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 certified
kit is used.
2. For propane/LP fireplace, 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)
• Reflective Glass

Firebox framing can be built before or after the appliance
is set in place. Refer to Figure 2 for fireplace and framing
dimensions. The framing headers may rest on the top of
the firebox 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 firebox (as you are facing it) and
your electricity will come in on the right side.
The firebox may be installed directly on a combustible floor
or raised on a platform of an appropriate height. When
the firebox is installed directly on carpeting, tile, or other
combustible material, other than wood flooring, the firebox
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 configuration to be used, framing and finishing 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, including permits and inspections.
The following factors should be taken into consideration:
• Clearance to side-wall, ceiling, woodwork, and windows. Minimum clearances to combustibles

• This fireplace may be installed along a wall, across a corner, or use an exterior chase. See
Figure 3 for suggested locations.
• Location should be out of high traffic areas and away from furniture and draperies due to
heat from appliance.
• Never obstruct the front opening of the fireplace.
• Do install in the vicinity where gasoline or other flammable liquids may be stored.
• Vent pipe routing. See Venting section found in this manual for allowable venting configura-
tions.
• These units can be installed in a bedroom. Refer to the National Fuel Gas Code ANSI Z233.1/
NFPA 54 — (current edition), the Uniform Mechanical Code — (current edition), and Local
Building Codes for specific installation requirements.
• These units can be installed in a bathroom.

The fireplace must be secured to the floor and/or to framing studs as shown in Figure 6. Use
two (2) wood screws or masonry/ concrete screws to secure fireplace to the floor. Use four (4)
screws to attach fireplace to framing. The side nailing flanges are 1/2" or 5/8" to accommodate
different wall thickness.

to final finishing to avoid costly reconstruction.
Only noncombustible materials (i.e. brick, tile, slate, steel, or other materials with a UL fire 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 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 finished wall and the fireplace surround are sealed, a 300°F minimum sealant material
(General Electric RTV103 or equivalent) must be used.

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 41. UL1777 flexible venting is also
approved for use on these models. Before installing vent
kit, the installer must read this fireplace 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
protection.
• Use extreme caution when using lad-
ders or when on rooftops.
• Be aware of electrical wiring locations
in walls and ceilings.
The following actions will void the warranty on
your venting system:
• Installation of any damaged venting
component.
• Unauthorized modification of the vent-
ing system.
• Installation of any component part not
manufactured or approved by MHSC.
• Installation other than permitted by these instruc-
tions.
