Startup / Checkout Fire Hazard Reset and Service by Qualified Technician only. If the burner or control fails any of the following tests, recheck control wiring. If the burner or control still fails any tests, replace the control. Starting the System 1. Open the shut-off valves in the supply line from the oil tank. 2. Close the disconnect switch to supply power to the burner. 3. Adjust the thermostat or boiler control to call for heat.
Sequence of Operation Burner States 1. Standby: The burner is idle, waiting for a call for heat. Standby 2 2. Valve-On Delay: The igniter and motor are on while the control delays turning on the oil solenoid valve for the programmed time. 3. Trial For Ignition: The oil solenoid valve is energized. A flame should be established within the factory set trial for ignition time (“lockout time”).
2. Initiate a call for heat. Priming the Pump 3. After the burner starts, press and hold the reset button for 15 seconds until the yellow light turns on. This indicates that the button has been held long enough. 1. Prepare the burner for priming by attaching a clear plastic hose over the bleed port fitting and fully opening the pump bleed port. Use a suitable container to collect purged oil. 4. Release the reset button. The yellow light will turn off and the burner will start up again.
automatically return to standby mode. 8. If prime is not established during the four minute pump prime mode, return to step 5 to re-enter Pump Prime mode. Repeat steps 5 through 7 until the pump is fully primed and the oil is free of bubbles. 9. Terminate the call for heat, and the control will resume normal operation. to limit accumulation of unburned oil in the combustion chamber. ◦ To reset, hold the button down for 15 seconds until the red light turns off and the yellow light turns on.
