RESET BUTTON OPERATION
Table 2 explains what action the control will take when the reset button is pressed for different lengths of
time during the various burner operating states.
Priming th Pump
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.
WARNING Hot Gas Puff-Back and Heavy Smoke Hazard
Failure to bleed the pump properly could result in unstable combustion, hot gas puff-back and heavy
smoke.
- Do not allow oil to spray into a hot combustion chamber while bleeding air from the pump.
- Install a gauge in the nozzle discharge port tubing or fully open the pump bleed valve to prevent oil
spray from accumulating in the combustion chamber during the air bleed procedure.
- Ensure that all bubbles and froth are purged from the oil supply system before tightening the pump
bleed valve.
- Ensure that the appliance is free of oil and vapor before starting or resetting the burner.
2. Initiate a call for heat.
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.
4. Release the reset button. The yellow light will turn off and the burner will start up again.
5. At burner start up, click the reset button while the igniter is still on. This will transition the control to a
dedicated Pump Prime mode, during which the motor, igniter, and valve are powered for four minutes.
The yellow light will be on.
6. Bleed the pump until all froth and bubbles are purged. If desired, terminate the call for heat or hold the
reset button for at least one second to exit Pump Prime mode and return to Standby.
