R7284B,P,U,G ELECTRONIC OIL PRIMARY, ENVIRACOM™ ENABLED
11 69-2467—01
No Ignition 20 Check that the manual shut off valve is open.
Check that the burner motor is spinning and the pump is generating
adequate pressure.
Check the condition of the nozzle and replace if necessary.
If a valve is present, check for proper operation.
Check burner adjustments (refer to burner manufacturers instructions)
Low Voltage, XX% low 59 Supply voltage is low to the control.
Measure the voltage across screw terminals “2” and “3”
If it's greater than 22VAC and the error does not clear, replace
control.
If it's less than 22VAC, review appliance wiring.
Internal Error 18, 58 An error has been detected inside the control. Replace control if the
error persists.
Flame Proven, Out of
Sequence
34 The cad cell is permanently in a low resistance state. It should typically
read much higher than 20,000 ohms when no flame is present.
Set the display to display cad cell resistance.
Shield the cad cell from light.
If the display shows less than 20,000 ohms, unplug the cad cell,
If display does not read 999999 ohms, replace control.
If it does read 999999 ohms, replace cad cell.
Flame Proven, During On
Delay
23 Flame was proven during the valve on delay period. Check the oil valve
for proper operation.
If the system does not have an oil valve, set the valve on delay to 0.
Flame Proven, During Off
Delay
24 Flame remained lit during the burner off delay. Check the oil valve for
proper operation.
If the system does not have an oil valve, set the burner off delay to 0.
Exceeded Max Recycles 22 Flame was lost more than the allowed number of times. The burner
lights, but does not remain lit.
Check that the fuel tank is not empty.
Check the fuel supply lines (and filter) for obstructions or air
Use the pump priming feature to purge the system of airCheck
Check that the burner motor is spinning and the pump is generating
adequate pressure.
If present, check operation of the oil valve.
If the problem persists, proceed to the “Cad Cell, High During Run”
corrective action.
EnviraCOM™ Error 91 Communications error has been detected.
Remove all devices from the EnviraCOM™ connections, 3-pin plug
and screw terminals “1-2-3”.
If the error does not clear within one minute, measure the voltage on
terminals “2” and “3”.
If the voltage across terminals “2” and “3” is between 20VAC and
30VAC, replace control.
If it is outside of that range, review appliance wiring. There should
be approximately 24VAC across “2” and “3”.
Cad Cell, High During Run 4 The cad cell resistance is higher than normal while running, the system
is in need of a tune up.
Check for proper alignment of the cad cell and clean the eye if
necessary.
Check if the pump is generating adequate pressure.
Check burner adjustments (refer to burner manufacturers instructions).
Check for excessive soot build up in the burner and flue.
Check for flue blockage.
Flame Proven, Late in Trial 9 The burner lit very late during the trial for ignition and is susceptible to
not lighting.
Check cad cell for proper alignment and clean if necessary.
Check burner adjustments (refer to burner manufacturers instructions)
Check electrodes and spring contacts (if equipped) and adjust per
manufacturers recommendations.
Check if the pump is generating adequate pressure.
Check the fuel supply lines and filter for obstructions.
