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.
Idle and Smoke Fuel Feed Rates and “P” Settings
When the TR-100 is in smoke mode or idling in cook mode, the AC auger is turned on and delivers fuel continuously
for 15 seconds and is then turned off . The smoke control switch sets the auger off time. The smoke mode/cook mode
idle fuel feed rates are as follows:
