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 flames. This heater is designed for vent­free operation with flue 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. Non­thermostat models may also be operated as a vented decorative (ANSI Z21.60) product by opening flue 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 confined 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 efficient 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 effi­cient, 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, fireplaces, 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 classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 5 through 7 will help you classify your space and provide adequate ventilation.

AIR FOR COMBUSTION
AND VENTILATION
Continued
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 defined 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 with openings gasketed or sealed
b. weather stripping has been added on
openable windows and doors
c. caulking or sealants are applied to ar-
eas such as joints around window and door frames, between sole plates and floors, between wall-ceiling joints, be­tween wall panels, at penetrations for plumbing, electrical, and gas lines, and at other openings.
If your home does not meet all of the three criteria above, proceed to
Fresh-Air Flow For Heater Location
Confined Space and Unconfined Space
The National Fuel Gas Code ANSI Z223.1/NFPA 54 defines a confined space as a space whose vol-
ume 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 un­confined space as a space whose volume is not less than 50 cubic feet per 1,000 Btu per hour (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 unconfined space.
* Adjoining rooms are communicating only if there are doorless passageways or ventilation grills be­tween them.

Space: Includes the room in which you will install fireplace 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:
(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:
51,200 (maximum Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in the space.
Vent-free fireplace _________ Btu/Hr
Gas water heater* _________ Btu/Hr
Gas furnace _________ Btu/Hr
Vented gas heater _________ Btu/Hr
Gas fireplace 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 fireplace + _________ Btu/Hr
Total = _________ Btu/Hr
4. Compare the maximum Btu/Hr the space can

Example:
The space in the example is a confined 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 uncon­fined space, remove door to adjoining room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 7.
B. Vent room directly to the outdoors. See Ventila-
tion Air From Outdoors, page 7.

C. Install a lower Btu/Hr fireplace, if lower Btu/Hr
size makes room unconfined.
If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an un­confined space. You will need no additional fresh air ventilation.
WARNING: If the area in which the heater may be oper­ated is smaller than that defined as an unconfined space or if the building is of unusually tight construction, provide adequate combustion and ventilation air by one of the methods described in the
