AFII Burner Manual
RECYCLE. If the fl ame is lost while the burner is 
fi ring, the control shuts down the burner, enters 
a 60 second recycle delay, and then repeats the 
above ignition sequence. If fl ame is lost three 
times in a row, the control locks out to prevent 
cycling with repetitious fl ame loss due to poor 
combustion.
BURNER MOTOR-OFF DELAY. The fuel valve 
is closed and the burner motor is kept on for the 
selected motor-off delay time before the control 
returns the burner to standby.

STANDBY. The burner is idle, waiting for a call for 
heat. When a call for heat is initiated, there is a 3-
10 second delay while the control performs a safe 
start check.
VALVE-ON DELAY. The ignition and motor are 
turned on for a 15 second valve-on delay.
TRIAL FOR IGNITION (TFI). The fuel valve is 
opened. A fl ame should be established within the 
15 second lockout time.
LOCKOUT. If fl ame is not sensed by the end of 
the TFI, the control shuts down on safety lockout 
and must be manually reset. If the control locks out 
three times in a row, the control enters restricted 
lockout. 
IGNITION CARRYOVER. Once fl ame is 
established, the ignition remains on for 10 seconds 
to ensure fl ame stability before turning off. If the 
control is wired for intermittent duty ignition, the 
ignition unit stays on the entire time the motor is 
running.
RUN. The burner runs until the call for heat is 
satifi ed. The burner is then sent to burner motor off 
delay, if applicable, or it is shut down and sent to 
standby.
