SAFETY FEATURES
Tip-Over Safety Feature
This heater is equipped with a tip-over safety feature. Once the heater is tipped over, an internal
switch will automatically shut the heater off. Once the heater is restored an upright position, the
heater will reset. To continue operation, turn on the heater using the supplied remote control or the
