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.

Do not allow fans to blow directly into the fireplace. Avoid drafts that alter burner flame patterns.

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 heater 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 heater.

4.Do not place clothing or other flammable material near the fireplace when the heater is in use.

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

6.Installation and repair should be done by a qualified service person. The appliance should be inspected 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 pas- sageways of the appliance be kept clean.

7.To prevent malfunction and/or sooting, an unvented gas heater should be cleaned at least annually by a professional service person. More frequent cleaning may be required due to excessive lint from carpeting, etc. It is imperative that control compart- ments, 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.
