Start the Burner and Set Combustion

SK9359

7.  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.

8.  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 re-

turns the burner to standby.

1.  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.

2.  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.

4.  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. 

5.  IGNITION  CARRYOVER.  Once  fl ame is estab-

lished, the ignition remains on for 10 seconds to 

ensure fl ame stability before turning off. If the con-

trol is wired for intermittent duty ignition, the ignition 

unit stays on the entire time the motor is running.

6.  RUN. The burner runs until the call for heat is sati-

fi ed. The burner is then sent to burner motor off 

delay, if applicable, or it is shut down and sent to 

standby.
