IMPORTANT SAFETY INFORMATION

INSTALLER

Please leave these instructions with the appliance.

IMPORTANT

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

• 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 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.

OWNER

Please retain these instructions for future reference

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.

10. This unit complies with ANSI Z21.91 ventless firebox enclosures for gas-fired unvented decorative room heaters.

11. Do not install heater in a bathroom or bedroom.

12. Correct installation of the 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. An unvented gas-fired heater uses air (oxygen) from the

room in which it is installed. Provisions for adequate combustion and ventilation air must be provided. See installation guidelines.

IMPORTANT SAFETY INFORMATION

Continued from page 3

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

17. Unvented gas heaters are a supplemental zone heater. They are not intended to be a 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.

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

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

26. Do not fill spaces around the firebox with insulation or other materials. These spaces must be maintained to prevent the firebox from coming in contact with combustible materials.

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

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

WARNING

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).

22. The appliance must be isolated from the gas supply piping system by closing its equipment shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5 kPa).

23. Do not use this room heater if any part has been under water. Immediately call a qualified service technician to inspect the room heater and to replace any part of the control system and any gas control which has been under water.
