SAFETY INFORMATION

PRODUCT IDENTIFICATION

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.

Do not place propane/LP supply tank(s) inside any structure. Lo-
cate propane/LP supply tank(s) outdoors (propane/LP units only).

3.

To prevent performance problems, the use of a propane/LP
fuel tank of less than 100 lb. capacity is not recommended
(propane/LP units only).

4.

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

5.

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).

6.

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 ig-
nite if highly heated. A dirty chimney flue may create and dis-
tribute soot within the house. Inspect chimney flue for dam-
age. If damaged, repair flue before operating heater.

7.

Do not burn solid-fuel in a masonry or UL127 factory-built
fireplace in which a vent-free room heater is installed.

8.

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. Make sure
there are no obstructions across openings of fireplace.

9.

This log heater is designed to be smokeless. If logs ever ap-
pear 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.

10. To prevent the creation of soot, follow the instructions in Clean-

ing and Maintenance, page 19.

11. Before using furniture polish, wax, carpet cleaner, or similar

products, turn heater off. If heated, the vapors from these prod-
ucts may create a white powder residue within burner box or
on adjacent walls or furniture.

12. This heater needs fresh, outside air ventilation 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 20 through 22.

SAFETY INFORMATION

Continued

13. Do not run heater

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

14. Do not use this heater to cook food or burn paper or other

objects.

15. Do not use heater if any part has been exposed to or under

water. Immediately call a qualified service technician to in-
spect the room heater and to replace any part of the control
system and any gas control which has been under water.

16. Do not operate heater if any log is broken. Do not operate

heater if a log is chipped (dime-sized or larger).

17. Turn heater off and let cool before servicing, installing, or re-

pairing. Make sure the remote selector switch is in the OFF
position. Only a qualified service person should install, ser-
vice, or repair heater.

18. Make sure the remote selector switch is in the OFF position

when you are away from home for long periods of time.

19. This heater must not be connected to any external electrical

source.

20. Operating heater above elevations of 4,500 feet may cause pi-

lot outage.

21. Provide adequate clearances around air openings.
