PRODUCT FEATURES
OPERATION
This heater is clean burning. It requires no outside
venting. There is no heat loss out a vent or up a
chimney. Heat is generated by realistic fl ames
and glowing ceramic logs/coals. This heater is
designed for vent-free operation with fl ue damper
closed. It has been tested and approved to ANSI
Z21.11.2 standard for unvented heaters. State
and local codes in some areas prohibit the use
of vent-free heaters. This heater may also be
operated as a vented decorative (ANSI Z21.60)
product by opening the fl ue damper.
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/NFPA 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:
SAFETY DEVICE
This heater has a pilot with an Oxygen Depletion
Sensing (ODS) safety shutoff system. The ODS/
pilot is a required feature for vent-free room heaters. The ODS/pilot shuts off the heater if there
is not enough fresh air.
ELECTRONIC IGNITION SYSTEM
This system has an electronic igniter. This
system requires no matches or other sources
to light heater. Receiver requires 4 AA batteries
(included), hand-held remote control requires a
12-volt battery and a 3-volt button cell battery
for the LCD display (both included).
1. Unusually Tight Construction
2. Unconfi ned Space
3. Confi ned Space
The information on Pages 6-8 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.
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 three criteria above,
you must provide additional fresh air. See
Ventilation Air From Outdoors, Page 8.
If your home does not meet all three criteria
above, proceed to Determining Fresh-Air
Flow For Heater Location, below.
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
-11
kg per pa-sec-m2) or less with

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
3
feet per 1,000 Btu/hr (4.8 m
per kw) of the aggregate input rating of all appliances installed
in that space and an unconfi ned space as
a space whose volume is not less than 50
3
cubic feet per 1,000 Btu/hr (4.8 m
per kw) of
the aggregate 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.
DETERMINING FRESH-AIR FLOW
FOR HEATER LOCATION
Determining if You Have a Confi ned or
Unconfi ned Space Using the Standard
Method
Use this work sheet to determine if you have
a confi ned or unconfi ned space.
Space: Includes the room in which you will install
fi replace plus any adjoining rooms with doorless passageways or ventilation grills between
the rooms.
1. Determine the volume of the space (length
x width x height).
Length x Width x Height =__________cu. ft.
(volume of space)
Example: Space size 20 ft. (length) x 16 ft.
(width) x 8 ft. (ceiling height) = 2560 cu. ft.
(volume of space)
If additional ventilation to adjoining room
is supplied with grills or openings, add the
volume of these rooms to the total volume
of the space.
2. Multiply the space volume by 20 to determine
the maximum Btu/Hr the space can support.
________ (volume of space) x 20 = (Maxi-
mum Btu/Hr the space can support)
Example: 2560 cu. ft. (volume of space) x
20 = 51,200 (maximum Btu/Hr the space can
support)
3. Add the Btu/Hr of all fuel burning appliances
in the space.
Vent-free fi replace __________Btu/Hr
Gas water heater* __________Btu/Hr
Gas furnace __________Btu/Hr
Vented gas heater __________Btu/Hr
Gas fi replace logs __________Btu/Hr
Other gas appliances* + _________Btu/Hr
Total = _________Btu/Hr
* Do not include direct-vent gas appliances.
Direct-vent draws combustion air from the
outdoors and vents to the outdoors.
Example:
Gas water heater __________Btu/Hr
Vent-free fi replace + _________Btu/Hr
Total = _________Btu/Hr
Compare the maximum Btu/Hr the space can
4.
support with the actual amount of Btu/Hr used.
_______ Btu/Hr (maximum can support)
_______ Btu/Hr (actual amount used)
Example: 51,200 Btu/Hr (maximum the
space can support)
73,000 Btu/Hr (actual amount of
Btu/Hr used)
The space in the above example is a confi ned
space because the actual Btu/Hr used is more
than the maximum Btu/Hr the space can support. You must provide additional fresh air. Your
options are as follows:
A. Rework worksheet, adding the space of an
adjoining room. If the extra space provides
an unconfi ned space, remove door to adjoin-
ing room or add ventilation grills between
rooms. See Ventilation Air From Inside
Building, Page 8.
B. Vent room directly to the outdoors. See
Ventilation Air From Outdoors, Page 8.
C. Install a lower Btu/Hr fi replace, if lower Btu/
Hr size makes room unconfi ned.
If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is
an unconfi ned space. Y ou will need no additional
fresh air ventilation.

This fresh air would come from an adjoining
unconfined space. When ventilating to an
adjoining unconfi ned space, you must provide
two permanent openings: one within 12" of the
ceiling and one within 12" of the fl oor on the wall
connecting the two spaces (see options 1 and
2, Figure 2). You can also remove door into
adjoining room (see option 3, Figure 2). Follow
the National Fuel Gas Code, ANSI Z223.1/
NFPA 54, Air for Combustion and Ventilation
for required size of ventilation grills or ducts.
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation
grills or ducts. You must provide two permanent openings: one within 12" of the ceiling
and one within 12" of the fl oor. Connect these
items directly to the outdoors or spaces open
to the outdoors. These spaces include attics
and crawl spaces. Follow the National Fuel
Gas Code, ANSI Z223.1/NFPA 54, Air for
Combustion and Ventilation for required size
of ventilation grills or ducts.
IMPORTANT: Do not provide openings
for inlet or outlet air into attic if attic has a
