To Complete the Adjustment Procedure– Either Brand Switch:
1. With electrical power remaining ON to the heater and heater operating, shut off the power to the
circulating pump. If the switch has been correctly adjusted, when the water pump stops, the
heater will shut off and the “FLO” code will display.
CAUTION: If the heater continues to operate with water pump off, readjust water pressure switch
to ensure heater will not run without water flow.
2. Reinstall heater front cover.
