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 ames. This heater is designed for vent-free operation with 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 ue damper.
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.
pIEzO IGNITION SYSTEM
This heater has a piezo ignitor. This system re­quires no matches, batteries or other sources to light heater.
AIR FOR COMbUSTION
AND VENTILATION
WARNING: This heater shall
not be installed in a conned space or unusually tight con­struction unless provisions are provided for adequate combus­tion and ventilation air. Read the following instructions to insure proper fresh air for this and other fuel-burning appliances in your home.
Today’s homes are built more energy efcient than ever. New materials, increased insulation and new construction methods help reduce heat loss in homes. Home owners weather strip and caulk around windows and doors to keep the cold air out and the warm air in. During heating months, home owners want their homes as airtight as possible.
While it is good to make your home energy ef­cient, your home needs to breathe. Fresh air must enter your home. All fuel-burning appliances need fresh air for proper combustion and ventilation.
119421-01A 5

AIR FOR COMbUSTION
AND VENTILATION
Continued
Exhaust fans, replaces, clothes dryers and fuel burning appliances draw air from the house to operate. You must provide adequate fresh air for these appliances. This will insure proper venting of vented fuel-burning appliances.
pROVIDING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas Code, ANSI Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation.
All spaces in homes fall into one of the three fol­lowing ventilation classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned Space
The information on pages 5 through 7 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 dened
as construction where:
a. walls and ceilings exposed to the out-
side atmosphere have a continuous water vapor retarder with a rating of one perm (6x10 less with 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 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 7.
If your home does not meet all of the three
criteria above, proceed to Determining Fresh-Air Flow for Heater Location.

Conned and Unconned Space
National Fuel Gas Code, ANSI Z223.1/NFPA 54 denes a conned space as a space whose
volume is less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kw) of the aggregate input
rating of all appliances installed in that space and
an unconned space as a space whose volume is not less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 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 unconned space.
* 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 Conned or Unconned Space
Use this work sheet to determine if you have a conned or unconned space.
Space: Includes the room in which you will install 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) = 2,560 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: 2,560 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 replace __________ Btu/Hr
Gas water heater* __________ Btu/Hr
Gas furnace __________ Btu/Hr
Vented gas heater __________ Btu/Hr
Gas replace logs __________ Btu/Hr
Other gas appliances* + ________ Btu/Hr
Total = ________ Btu/Hr
* Do not include direct-vent gas appliances. Di-
rect-vent draws combustion air from the outdoors and vents to the outdoors.

Btu/Hr (maximum the space can support)
Btu/Hr (actual amount of Btu/Hr used)
Example: 51,200 Btu/Hr (maximum the space
can support)
79,000 Btu/Hr (actual amount of
Btu/Hr used)
The space in the example is a con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 adjoin-
ing room. If the extra space provides an unconned space, remove door to adjoining room or add ventilation grills between rooms. See Ventilation
Air From Inside Building.
B. Vent room directly to the outdoors. See Ventila-
tion Air From Outdoors.
C. Install a lower Btu/Hr replace, if lower Btu/Hr
size makes room unconned.
If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an un­conned space. You will need no additional fresh air ventilation.
WARNING: If the area in
which the heater may be oper­ated is smaller than that dened as an unconned space or if the building is of unusually tight construction, provide adequate combustion and ventilation air by one of the methods described
in the National Fuel Gas Code, ANSI Z223.1/NFPA 54 Section 5.3
or applicable local codes.

ventilation grills or ducts.
Figure 2 - Ventilation Air from Inside
Building
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 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, Section 5.3, 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 thermostat­controlled power vent. Heated air entering the attic will activate the power vent.
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining un­conned space. When ventilating to an adjoining unconned space, you must provide two perma­nent openings: one within 12" of the ceiling and one within 12" of the oor on the wall connecting

NOTICE: This heater is intended
for use as supplemental heat. Use this heater along with your primary heating system. Do not install this heater as your pri­mary heat source. If you have a central heating system, you may run system’s circulating blower while using log heater. This will help circulate the heat from your log heater throughout the house. In the event of a power outage,
you can use this heater as your
primary heat source.
WARNING: A qualied ser­vice person must install heater. Follow all local codes.
NOTICE: State or local codes may
only allow operation of this appli­ance in a vented conguration. Check your state or local codes.
WARNING: Before installing in a solid fuel burning replace, the chimney ue and rebox must be cleaned of soot, creo­sote, ashes and loose paint by a qualified chimney cleaner. Creosote will ignite if highly heated. A dirty chimney ue may create and distribute soot within house. Inspect chimney ue and rebox for damage. If damaged, repair ue and rebox before operating heater.
WARNING: Seal any fresh air vents or ash clean-out doors
located on oor or wall of re­place. If not, drafting may cause pilot outage or sooting. Use a heat-resistant sealant. Do not seal chimney ue damper.
