Service Notes - Polarity & Ground
This water heater is polarity and ground sensitive. The control system will lock out and
display a fault message ("AC Reversed") if the power supply polarity is reversed. Flame
sensing current cannot be established if the burner is not grounded which will lead to ignition
failure. See electrical requirements on page 8.
