person should service and repair heater.

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.

IGNITION SYSTEM

This heater has either a piezo ignitor or electronic ignitor to light
heater fuel supply.

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.
