STARTING AND ADJUSTING THE BURNER
Preparing the burner for start up:
(1) Plug the black cord into the top of the burner.
(2) Turn on electrical power to the furnace.
(3) Allow the burner heater element sufficient time to warm up the burner (time will vary
according to ambient temperature). This usually takes 5 - 10 minutes. Once the burner
has warmed up the “proving switch” will close and send power to the oil primary control.
(4) Close the combustion air intake on the side of the burner. This will be opened up and
adjusted once a flame is established.
(5) Adjust the wall thermostat 10 - 20
O
F above room temperature.
(6) The burner should start when there is a call for heat. If the burner does not start, wait a
few more minutes to ensure the burner is warmed up. If the burner still does not start try
resetting the oil primary control (refer to the section on “Resetting the Oil Primary Control”
in this manual).
Priming the oil pump:
(1) After the burner starts, press and hold the reset button for 15 seconds until the small
yellow light on the primary control (“Pump Prime”) turns on (the burner will shut off).
(2) Release the reset button. The yellow light will turn off and the burner will start again.
(3) Within 15 seconds click (push and release) the reset button. This will transition the
primary control to “Pump Prime” mode which will bypass the flame sensor and keep the
pump on for 4 minutes.
(4) Open the pump bleeder valve and purge all air bubbles from the pump (refer to figure 24).
(5) After 4 minutes the yellow light on the primary control will turn off and the control will
automatically return to standby mode.
(6) Repeat steps 1 - 5 until the pump is fully primed and oil is delivered to the burner.
Adjusting the burner:
(1) Once a flame is established adjust the combustion air intake and the compressed air
pressure to maintain a healthy flame (refer to Figure 25).
(2) The air intake plate on the left side of the burner can be adjusted to increase or decrease
the pie shaped opening sizes to let in more or less combustion air.
(3) The compressed air pressure can be adjusted by turning the knob on the air regulator.
(4) Visually inspect the flame to ensure proper settings.
(5) The flame should go 1/2 to 3/4 of the way down the combustion chamber, and should not
impinge on any surface of the combustion chamber.
CAUTION:
Failure to prime the pump properly can result in unstable combustion, puff
back, and heavy smoke.
