 WARNINGS 

Continued

WARNING: 

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

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
• do not touch any electrical switch; do not use any phone in your building
• 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 except as a vented

appliance (see page 13).

4. Never install the heater

• in a recreational vehicle
• where curtains, furniture, clothing, or other flammable objects are less than 36

inches from the front, top, or sides of the heater

• in high traffic areas
• in windy or drafty areas

5. Before installing in a solid fuel burning fireplace, the chimney flue and firebox 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 operate 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 opening has vents at the bottom, you must open the vents before operating heater.

7. You must operate this heater with a fireplace screen in place. Make sure fireplace screen

is closed before running heater.

8. This log heater is designed to be smokeless. If logs ever appear to smoke, turn off heater

and call a qualified service person. 

Note:

 During initial operation, slight smoking could

occur due to log curing and heater burning manufacturing residues.

9. 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.

10. Do not use a blower insert, heat exchanger insert or other accessory not approved for

use with this heater.

11. This heater needs fresh, outside air ventilation to run properly. This heater has an oxygen

depletion sensor (ODS) pilot light safety system. The ODS shuts down the heater if not
enough fresh air is available. See Air for Combustion and Ventilation, pages 5 through
7. If heater keeps shutting off, see Troubleshooting, pages 25 through 28.

12. Do not run heater

• where flammable liquids or vapors are used or stored
• under dusty conditions

13. Do not use this heater to cook food or burn paper or other objects.
14. Never place any objects on the heater.
15. 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 before touching.

16. Carefully supervise young children when they are in the room with heater.
17. Do not use heater if any part has been exposed to or 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.

18. Do not operate heater if any log is broken. Do not operate heater if a log is chipped (dime-

sized or larger).

19. Turn heater off and let cool before servicing. Only a qualified service person should

service and repair heater.

20. Operating heater above elevations of 4,500 feet could cause pilot outage.
