1. Do not place Propane/LP supply tank(s)
inside any structure. Propane/LP supply
tank(s) must be placed outdoors.
2. Heaters with a maximum input over
6,000 Btu/Hr shall not be installed in a
bathroom. Heaters with a maximum input
over 10,000 Btu/Hr shall not be installed
in a bedroom.
3. This heater needs fresh 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
6 and 7. If heater keeps shutting off, see
Troubleshooting
, page 20.
4. Keep all air openings in front and bottom
of heater clear and free of debris. This will
ensure enough air for proper combustion.

have provided fresh, outside air. If heater
keeps shutting off, have it serviced.
6. Do not run heater:
• Where flammable liquids or vapors are
used or stored.
• Under dusty conditions.
SAFETY
7. 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.
8. Always run heater with control knob at
PILOT/IGN, LOW (1) or HIGH (5) locked
positions. Never set control knob between
locked positions. Poor combustion and
higher levels of carbon monoxide may
result.
9. Do not use heater if any part has been
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.
10. Turn off and unplug heater and let cool
before servicing. Only a qualified service
person should service and repair heater.
