set control knob between locked positions.
Poor combustion and higher levels of carbon
monoxide may result.
6. 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
not enough fresh air is available. See
Air for
Combustion and Ventilation,
page 5.
7. Keep all air openings in front and bottom of
heater clear and free of debris. This will insure
enough air for proper combustion.

provide fresh, outside air. If heater keeps
shutting off, have it serviced.

• where flammable liquids or vapors are used
or stored
• under dusty conditions
10. 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.
11. Turn off and unplug heater and let cool before
servicing. Only a qualified service person
should service and repair heater.
12. Operating heater above elevations of 4,500
feet could cause pilot outage.
13. To prevent performance problems, do not use
propane/LP fuel tank of less than 100 lbs.
capacity.
14. Before using furniture polish, wax, carpet
cleaner or similar products, turn heater off. If

PRODUCT FEATURES
SAFETY DEVICE
This heater has a pilot with an Oxygen Deple-
tion Sensing (ODS) safety shutoff system. The
ODS/pilot is a required feature for vent-free room
heaters. The ODS/pilot shuts off the heater if there
is not enough fresh air.
IGNITION SYSTEM
This heater has either a piezo ignitor or electronic
ignitor to light heater fuel supply.
THERMOSTATIC HEAT CONTROL
(Thermostat Models Only)
Thermostat models have a thermostat sensing
bulb and a control valve. This results in the great-
est heater comfort. This can also result in lower
gas bills.
