PRIMING THE PUMP
WARNING
Hot Gas
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 air bleed valve.
1.Prepare the burner for priming by fully opening the pump bleed port and attaching a clear plastic hose over the bleed port fitting. Use a suitable container to collect purged oil.
2.Initiate a call for heat.
3.After the burner starts, press and hold the reset button for 15 seconds until the yellow LED turns on. This indicates that the button has been held long enough.
4.Release the reset button. The yellow LED will turn off and the burner will start up again.
5.At burner start up, tap the reset button within the first 10 seconds of the ignition cycle. 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 LED will be on.
6.Bleed the pump until all froth and bubbles are purged. If desired, hold the reset button for at least one second to exit Pump Prime mode and return to Standby.
7.At the end of 4 minutes, the yellow LED will turn off and the control will automatically return to standby mode.
8.If prime is not established during the four minute pump prime mode, return to step 5 to
9.Terminate the call for heat, and the control will resume normal operation.
CAD CELL RESISTANCE INDICATOR
•During the burner Run state, tap the reset button (less than 1 second) to check the cad cell resistance range. The yellow LED will flash 1 to 4 times depending on the amount of light detected by the cad cell. See chart below:
