SAFETY 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.

 WARNINGS DANGER: Carbon monoxide poisoning may lead to death!

Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning re- semble 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 affected by carbon monoxide than others. These include pregnant women, people with heart or lung disease or anemia, those under the influence 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.

Make certain you read and understand all Warnings. Keep this manual for reference. It is your guide to safe and proper operation of this heater.

5.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.

6.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.

8.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.

9.Do not allow fans to blow directly into the fireplace. Avoid any drafts that al- ter burner flame patterns. Ceiling fans

may create drafts that alter burner flame patterns. Altered burner patterns can cause sooting.

10.Do not use a blower insert, heat ex- changer insert or other accessory not approved for use with this heater.

11.This heater needs fresh, outside air ven- tilation to run properly. This heater has an oxygen depletion sensor (ODS) pi- lot light safety system. The ODS shuts down the heater if not enough fresh air is available. See Air for Combustion and Ventilation, pages 4 and 5. If heater keeps shutting off, see Troubleshoot- ing, pages 18 through 20.
