WARNINGS

IMPORTANT: Read this owner’s manual carefully and completely before trying to assemble, oper- ate, or service this heater. Im- proper use of this heater can cause serious injury or death from burns, fire, explosion, electrical shock, and carbon monoxide poisoning.

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 work- ing properly. Get fresh air at once! Have heater serviced. Some people are more af- fected by carbon monoxide than others. These include pregnant women, people with heart or lung disease or anemia, those under the influ- ence of alcohol, and those at high altitudes.

Natural Gas: Natural gas is odorless. An odor-making agent is added to the gas. The odor helps you detect a gas leak. However, the odor added to the gas can fade. Gas may be present even though no odor exists.

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. When using the hand- held remote accessory, keep se- lector switch in the OFF position to prevent children from turning on burners with remote.

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

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 per- son. Note: During initial operation, slight smoking may occur due to log curing and heater burning manufacturing residues.

7.To prevent the creation of soot, follow the instructions in Cleaning and Main- tenance, page 18.

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 19 through 21.
