AC Auger
The grill is equipped with an AC auger. AC augers operate at a single speed and deliver fuel at a constant rate while
on The fuel feed rate (amount of fuel delivered in a given period of time) is adjusted by varying the on and off
time intervals.
Duty Cycle The ratio of time the auger is on is sometimes referred to as the duty cycle and is expressed as a percent-
age For example, if the auger is always on, its duty cycle is 100 percent If the auger is on half the time, its duty cycle is
50 percent, etc.
