ance. See Installing Damper Clamp Accessory
for Vented Operation, page 11.
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, repair flue before operating heater.
6. Do not burn solid-fuel in a masonry or UL127
factory-built fireplace in which a vent-free
room heater is installed.
7. If fireplace has glass doors, never operate this
heater with glass doors closed. If you operate

are no obstructions across opening of fireplace.
8. To prevent the creation of soot, follow the instruc-
tions in Cleaning and Maintenance, page 21.
9. Before using furniture polish, wax, carpet
cleaner or similar products, turn heater off. If
heated, the vapors from these products may
create a white powder residue within burner
box or on adjacent walls and furniture.

to run properly. This heater has an Oxygen
Depletion Sensing (ODS) safety shutoff sys-
tem. The ODS shuts down the heater if enough
fresh air is not available. See Air for Combus-
tion and Ventilation, page 5. If heater keeps
shutting off, see Troubleshooting, page 22.

• where flammable liquids or vapors are
used or stored

paper or other objects.

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.
14. Do not operate heater if any log is broken. Do
not operate heater if a log is chipped (dime-
sized or larger).
15. Turn heater off and let cool before servicing,
installing or repairing. Only a qualified service
person should install, service or repair heater.
16. Operating heater above elevations of 4,500
feet may cause pilot outage.
