PRODUCT FEATURES
SAFETY DEVICE
This heater has a pilot with an Oxygen Depletion 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.
PIEZO IGNITION SYSTEM
This heater has a piezo ignitor. This system requires no matches,
batteries, or other sources to light heater.
THERMOSTATIC HEAT CONTROL
Thermostat models have a thermostat sensing bulb and a control
valve. This results in the greatest heater comfort. This can also result
in lower gas bills.
