Understanding Idle Fuel Feed Rate and Smoke Settings

Smoke Control The Smoke Control switch sets the fuel feed rate (the
Switch amount of fuel delivered in a given period of time) when the

grill is operating in Smoke Mode and when the grill is idling
in Cook Mode.

During cook idle or smoke mode, the auger turns on,

delivers fuel for 15 seconds, then turns off. The off time is
set by the Smoke Control switch.

“P” Settings The fuel feed rate setting is displayed momentarily

whenever the Cook Control switch is set to the Smoke
position. It is also displayed whenever the Smoke Control
switch is adjusted. The setting is designated with the letter
“P” and a number. The greater the “P” setting number the
greater the auger off time.

P 0 15 seconds 45 seconds
P 1 15 55
P 2 15 65
P 3 15 75
P 4 15 85
P 5 15 95
P 6 15 105
P 7 15 115
P 8 15 125

switch, the auger delivers fuel for 15 seconds, turns off for
75 seconds, and repeats in Smoke Mode. It also delivers
fuel for 15 seconds, turns off for 75 seconds and repeats
while idling at or above the selected set temperature in Cook
Mode.

17

Cook Mode The Idle Fuel Feed Rate is the rate of fuel delivery that
Idle Fuel Feed Rate maintains the fire in the fire pot without raising the grill’s

temperature.

In Cook Mode, whenever the grill temperature is at or above

the set temperature, the auger runs at the Idle Fuel Feed
Rate. If the grill temperature is below the set temperature,
the auger operates per the On Fuel Feed Rate.

We recommend the “P2” setting as the default Idle Fuel

Feed Rate while in Cook Mode.

For the experienced operator, the auger Idle Fuel Feed Rate

can be adjusted to improve the grill's performance. For
example, to optimize temperature stability at a high
temperature setting, select “P1” or “P0” to increase the
auger Idle Fuel Feed Rate. Or, if due to ambient conditions
the grill is unable to cool down enough to reach a low
temperature setting such as 180 degrees, select “P3”, “P4”,
or higher to decrease the Idle Fuel Feed Rate.

High Temperature In Cook Mode, the Idle Fuel Feed Rate for the High
Idle Fuel Feed Rate temperature setting is preprogrammed into the control. The

idle fuel feed auger timing at High is 15 seconds on / 15
seconds off and is independent of the Smoke Control switch
"P" setting. The preprogrammed fuel feed rate helps
maintain the elevated cooking temperature at the High
setting.

Smoke Mode In Smoke Mode, increasing the “P” setting decreases the
Fuel Feed Rate fuel feed rate, lowering the grill temperature. Start at

setting “P2”, adjust the “P” setting manually for the desired
temperature and/or smoke output.

18

Error Modes and Messages

Inadvertent Start If the Cook Control switch is set to Smoke or to a
Error (ErP) temperature setting at the time the grill is plugged in, the

control will display “ErP” indicating an Inadvertent Start
Error. The standard ignition sequence is halted.

This feature prevents an inadvertent start. For example, if

the grill is stored in the garage, the grill will not ignite if
plugged in inadvertently.

To clear the error, set the Cook Control switch to the Off

position.

High Temperature If the grill temperature exceeds 615 degrees, the control
Limit Error (ErH) displays “ErH” indicating a High Temperature Limit Error.

The fuel feed auger is turned off, the igniter is turned off,

and the draft fan is turned off.

To clear the error, set the Cook Control switch to the Off

position. If the error will not clear, your temperature
detector is not functioning normally. See “Display is

AC Auger Theory of Operation

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 percentage. 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.
