J4350 - 50", cat. no. J4351 - 42",
or cat. no. J4352 - 36" only . This
hood has been designed to keep
the operation of your fi replace
safe and effi cient.
1. Do not use this fi rebox as a wood burning
fi replace. Use only decorative unvented
room heaters (log sets).
2. Do not add extra logs or ornaments such as
pine cones, vermiculite or rock wool. Using
these added items can cause sooting.
3. Use only the provided hood. See Parts,
Page 18. The firebox canopy (hood)
must not be modifi ed or replaced with a
canopy (hood) that may be provided with
the unvented decorative room heater.
4. Vent-free gas log heaters installed in these
fi reboxes require fresh air ventilation to
run properly . See Air for Combustion and
Ventilation, Page 8.
5. Do not run vent-free heaters installed in
these fi reboxes
• where fl ammable liquids or vapors are
used or stored
• under dusty conditions

AIR FOR COMBUSTION AND VENTILATION
WARNING: This heater shall not
be installed in a room or space unless the required volume of indoor
combustion air is provided by the
method described in the National
Fuel Gas Code, ANSI Z223.1/NFP A
54, the International Fuel Gas
Code, or applicable local codes.
Read the following instructions
to ensure proper fresh air for this
and other fuel-burning appliances
in your home.
Today’s homes are built more energy effi cient
than ever. New materials, increased insulation
and new construction methods help reduce heat
loss in homes. Homeowners apply weather strip
and caulk around windows and doors to keep
the cold air out and the warm air in. During heating months, homeowners want their homes as
airtight as possible.
While it is good to make your home energy
effi cient, your home needs to breathe. Fresh
air must enter your home. All fuel-burning appliances need fresh air for proper combustion
and ventilation.
Exhaust fans, some fi replaces, clothes dryers
and some fuel-burning appliances draw air from
the house to operate. Y ou must provide adequate
fresh air for these appliances. This will ensure
proper venting of vented fuel-burning appliances.
PROVIDING ADEQUA TE VENTILA TION
The following are excerpts from National Fuel
Gas Code, ANSI Z223.1/NFPA 54, Air for Combustion and Ventilation.
All spaces in homes fall into one of the three
following ventilation classifi cations:
1. Unusually Tight Construction
2. Unconfi ned Space
3. Confi ned Space
The information on Pages 8 through 10 will help
you classify your space and provide adequate
ventilation.
Unusually Tight Construction
The air that leaks around doors and windows
may provide enough fresh air for combustion and
ventilation. However, in buildings of unusually
tight construction, you must provide additional
fresh air.
SuperiorFireplaces.US.com
Unusually tight construction is defi ned as
construction where:
a. walls and ceilings exposed to the outside
atmosphere have a continuous water
vapor retarder with a rating of one perm
(6 x 10
openings gasketed or sealed and
b. weather stripping has been added on
openable windows and doors and
c. caulking or sealants are applied to areas
such as joints around window and door
frames, between sole plates and fl oors,
between wall-ceiling joints, between
wall panels, at penetrations for plumbing, electrical and gas lines and at other
openings.
If your home meets all of the three criteria
above, you must provide additional fresh air.
See Ventilation Air From Outdoors, Page 10.
If your home does not meet all of the three
criteria above, proceed to Determining Fresh-
Air Flow For Firebox Location.
Confi ned and Unconfi ned Space
The National Fuel Gas Code, ANSI Z223.1/
NFPA54 allows two methods for determining
whether the space in which the heater is being
installed is confi ned or unconfi ned space. The
standard method defi nes a confi ned space as a
space whose volume is less than 50 cubic feet
per 1,000 Btu per hour (4.8 m
gregate input rating of all appliances installed in
that space and an unconfi ned space as a space
whose volume is not less than 50 cubic feet per
1,000 Btu per hour (4.8 m
gregate input rating of all appliances installed in
that space. Rooms communicating directly with
the space in which the appliances are installed*,
through openings not furnished with doors, are
considered a part of the unconfi ned space.
Where the air infi ltration rate of a structure is
known, the Known Air Infi ltration Rate Method
may be used. Follow The National Fuel Gas
Code, ANSI Z223.1/NFPA 54 to use this
method to determine if the space is confi ned
or unconfi ned.
* Adjoining rooms are communicating only if
there are doorless passageways or ventilation
grills between them.
