IMPORTANT

Read these instructions carefully before installing or trying to operate this vent-free gas heater.

• Any change to this heater or its controls can be dangerous.

• Improper installation or use of the heater can cause serious injury or death from ﬁ re, burns, explosion or carbon monoxide poisoning.

• Do not allow fans to blow directly into the ﬁ replace. Avoid any drafts that alter burner ﬂ ame patterns.

WARNING

• Do not use a blower insert, heat exchanger insert or other accessory, not approved for use with this heater where applicable.

1. Due to high temperatures, the appliance should be located out of traffic and away from furniture and draperies.

2. Children and adults should be alerted to the hazard of high surface temperature and should stay away to avoid burns or clothing ignition.

3. Young children should be carefully supervised when they are in the same room with the appliance.

4. Do not place clothing or other flammable material on or near the appliance.

5. Any safety screen or guard removed for servicing an appliance, must be replaced prior to operating the heater.

6. Installation and repair should be done by a qualified service person.

7. To prevent malfunction and/or sooting, an unvented gas heater should be cleaned before use and at least annually by a professional service person. More frequent cleaning may be required due to excessive lint from carpeting, bedding material, etc. It is imperative that control compartments, burners and circulating air passageways be kept clean.

8. CARBON MONOXIDE POISONING: Early signs of

carbon monoxide poisoning are similar to the flu with headaches, dizziness and/or nausea. If you have these signs, obtain fresh air immediately. Have the heater serviced as it may not be operating properly.

9. The installation must conform with local codes or, in

the absence of local codes, with the National Fuel Gas

Code, ANSI Z223.l/NFPA54.

OWNER

Please retain these instructions for future reference

10. This unit complies with the latest revision of ANSI Z21.11.2 Unvented Heaters and also complies with ANSI Z21.60 Decorative Vented Appliances for Solid Fuel Burning Fireplaces. State and local codes may only allow operation of this appliance in a vented configuration. Check your state or local codes. For vented operation, see “Vented Instructions” in this manual.

11. Do not install the heaters in a bathroom or bedroom.

12. Correct installation of the ceramic fiber logs, proper

location of the heater, and annual cleaning are necessary to avoid potential problems with sooting. Sooting, resulting from improper installation or operation, can settle on surfaces outside the fireplace. See log placement instructions for proper installation.

13. Avoid any drafts that alter burner flame patterns. Do not

allow fans to blow directly into fireplace. Do not place a blower inside burn area of firebox. Ceiling fans may create drafts that alter burner flame patterns. Sooting and improper burning will occur.

14. Caution: Candles, incense, oil lamps, etc. produce

combustion byproducts including soot. Vent-free appliances will not filter or clean soot produced by these types of products. In addition, the smoke and/or aromatics (scents) may be reburnt in the vent-free appliance which can produce odors. It is recommended to minimize the use of candles, incense, etc. while the vent-free appliance is in operation.

15. This is an unvented gas-fired heater. It uses air (oxygen)

from the room in which it is installed. Provisions for adequate combustion and ventilation air must be provided. See page 8.

IMPORTANT SAFETY INFORMATION

Continued from page 3

16. Keep room area clear and free from combustible materials, gasoline and other flammable vapors and liquids.

25. Never burn solid fuels in a fireplace where a unvented room heater is installed.

17. Unvented gas heaters are a supplemental zone heater. They are not intended to be the primary heating appliance.

18. Unvented gas heaters emit moisture into the living area. In most homes of average construction, this does not pose a problem. In houses of extremely tight construction, additional mechanical ventilation is recommended.

19. During manufacturing, fabricating and shipping, various components of this appliance are treated with certain oils, films or bonding agents. These chemicals are not harmful but may produce annoying smoke and smells as they are burned off during the initial operation of the appliance; possibly causing headaches or eye or lung irritation. This is a normal and temporary occurrence.

The initial break-in operation should last two to three

hours with the burner at the highest setting. Provide maximum ventilation by opening windows or doors to allow odors to dissipate. Any odors remaining after this initial break-in period will be slight and will disappear with continued use.

20. Input ratings are shown in BTU per hour and are for elevations up to 2,000 feet. For elevations above 2,000 feet, input ratings should be reduced 4 percent for each 1,000 feet above sea level. Refer to the National Fuel Gas Code.

21. The appliance and its appliance main gas valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa).

26. Always have a fireplace screen in place when the appliance is in operation and, unless other provisions for combustion air are provided, the screen must have an opening(s) for induction of combustion air.

Never connect unit to private (nonutility) gas wells. This gas is commonly known as wellhead gas.

WARNING

We suggest that our gas hearth products be installed and serviced by professionals who are certiﬁ ed in the U.S. by the National Fireplace Institute (NFI) as Gas Specialists.

www.nﬁ certiﬁ ed.org

MASSACHUSSETTS RESIDENTS ONLY:
