DANGER: Carbon monoxide poisoning may lead to death!

Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning resemble the flu, with headaches, dizziness, or nausea. If you have these signs, the heater may not be working properly. Get fresh air at once! Have heater serviced. Some people are more affectedbycarbonmonoxidethanothers.These include pregnant women, people with heart or lung disease or anemia, those under the influ- ence of alcohol, and those at high altitudes.

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

WARNING: Do not allow fans to blow directly into the fireplace. Avoid any drafts that alter burner flame patterns. Ceiling fans can create drafts that alter burner flame patterns. Altered burner patterns can cause sooting.

WARNING: Do not use a blower insert, heat exchanger insert, or other accessory not ap- proved for use with this heater.

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

Do not place clothing or other flammable material on or near the appliance. Never place any objects on the heater.

Heater base assembly becomes very hot when running heater. Keep children and adults away from hot surface to avoid burns or clothing ignition. Heater will remain hot for a time after shut- down. Allow surface to cool be- fore touching.

Carefully supervise young chil- dren when they are in the room with heater.

You must operate this heater with a fireplace screen in place. Make sure fireplace screen is closed before running heater.

Keep the appliance area clear and free from combustible materials, gasoline, and other flammable vapors and liquids.

1.This appliance is only for use with the type of gas indicated on the rating plate. This appliance is not convertible for use with other gases.

2.If you smell gas

shut off gas supply

do not try to light any appliance

immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions

if you cannot reach your gas supplier, call the fire department

3.This heater shall not be installed in a bedroom or bathroom, unless installed as a vented appliance (see Installing Damper Clamp Accessory for Vented Operation, page 10).

4.Before installing in a solid fuel burn- ing fireplace, the chimney flue and fire- box must be cleaned of soot, creosote, ashes, and loose paint by a qualified chimney cleaner. Creosote will ignite if highly heated. Inspect chimney flue for damage. If damaged, operate heater with flue damper closed.

5.If fireplace has glass doors, never op- erate this heater with glass doors closed. If you operate heater with doors closed, heat buildup inside fireplace will cause glass to burst. Also if fireplace open- ing has vents at the bottom, you must open the vents before operating heater.

6.This log heater is designed to be smoke- less. If logs ever appear to smoke, turn off heater and call a qualified service person. Note: During initial operation, slight smoking may occur due to log curing and heater burning manufactur- ing residues.

7.To prevent the creation of soot, follow the instructions in Cleaning and Main- tenance, page 16.

8.Before using furniture polish, wax, car- pet cleaners, or similar products, turn heater off. If heated, the vapors from these products may create a white pow- der residue within burner box or on adjacent walls or furniture.

9.This heater needs fresh, outside air ven- tilation to run properly. This heater has an Oxygen Depletion Sensing (ODS) safety shutoff system. The ODS shuts down the heater if not enough fresh air is available. See Air for Combustion and Ventilation, pages 4 through 6. If heater keeps shutting off, see Trouble- shooting, pages 17 through 19.

10.Do not run heater

where flammable liquids or vapors are used or stored

under dusty conditions
