4. This heater shall not be installed in a bedroom
or bathroom, unless installed as a vented appli-
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. A dirty chimney
flue may create and distribute soot within
the house. Inspect chimney flue for damage.
If damaged, repair flue and firebox 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 fire-
place will cause glass to burst. Make sure there
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.
10. 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 enough fresh
air is not available. See Air for Combustion and
Ventilation, page 5. If heater keeps shutting off,
see Troubleshooting, page 23.
