• 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.
• Check the fuel supply lines and filter for obstructions or air.
• Check the electrodes, spring contacts (or high voltage wires), and ignition transformer for
proper operation.
• If a valve is present, check for proper operation.
• Check burner adjustments (refer to burner manufacturers instructions) and spark was not
detected.
• Check the cad cell positioning and clean the eye.
• Expose the cad cell to ambient light (generally enough light to read by is adequate)
— If the LED does not turn on, short the cad cell terminals,
— If the LED does not turn on, replace the control,
— If the LED turns on, replace the cad cell.
• Shield the cad cell from light.
— If the LED does not turn off, unplug the cad cell,

4 59,91 • Supply voltage was low to the control or a communication error has occurred.
• Remove all devices from the EnviraCOM™ connections, 3-pin plug and screw terminals
“1-2-3”.
— Measure the voltage across screw terminals “2” and “3”
If it's between 22VAC and 30VAC and the error does not clear, replace control.
— If it's outside that range, review appliance wiring. There should be approximately 24VAC
across “2” and “3”.
5 18, 58 An error has been detected inside the control. Replace control if the error persists.
