bathroom, unless installed as a vented appliance.
5. Before installing in a solid fuel burning fire-
place, 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. A dirty chimney flue
may create and distribute soot within the house.
Inspect chimney flue and firebox 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
heater with doors closed, heat buildup inside
fireplace will cause glass to burst. Make sure there
are no obstructions across openings of fireplace.
8. To prevent the creation of soot, follow the
instructions in Cleaning and Maintenance,
page 19.
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.
10. This heater needs fresh, outside air ventilation to
run properly. This heater has an Oxygen Deple-
tion Sensing (ODS) safety shutoff system. The
ODS shuts down the heater if enough fresh air
is not available. See Air for Combustion and
Ventilation, page 5. If heater keeps shutting off,
see Troubleshooting, page 20.
