Start-up, calibration and operation of the burner Burner ignition Once the above steps are complete, the burner should light. If the motor starts up, but the flame does not appear and the control box goes into lockout, reset it and wait for a new ignition attempt. If ignition is still not achieved, it may be that gas is not reaching the combustion head within the safety time period of 3 seconds.
