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, dancing yellow fl ames. 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 product (ANSI Z21.60) by
opening fl ue damper (non-thermostat operation
only).
APPLICATION
These multisided logs are designed to be equally
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.

SAFETY PILOT
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.

following ventilation classifi cations:
1. Unusually Tight Construction
2. Unconfi ned Space
3. Confi ned Space
The information on Pages 6-8 will help you clas-
sify 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
126848-01B6
AIR FOR COMBUSTION AND VENTILATION
Continued
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
cubic feet per 1,000 Btu/hr (4.8 m
3
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.
