cessory for Vented Operation, page 11).
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 quali-
fied chimney cleaner. Creosote will ignite if
highly heated. A dirty chimney flue may cre-
ate and distribute soot within the house. In-
spect chimney flue for damage. If damaged,
repair flue and firebox 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.

heater with glass doors closed. If you operate
heater with doors closed, heat buildup inside fire-
place 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 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.
10. To prevent the creation of soot, follow the in-
structions in Cleaning and Maintenance, pages
24 and 25.
11. 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 or furniture.
12. This heater needs fresh, outside air ventila-
tion to run properly. This heater has an Oxy-
gen Depletion Sensing (ODS) safety shutoff
system. The ODS shuts down the heater if not
enough fresh air is available. See Air for Com-
bustion and Ventilation, pages 5 through 7. If
heater keeps shutting off, see Troubleshoot-
ing, pages 26 through 28.
13. Do not run heater
• where flammable liquids or vapors are used
or stored
