This is how your “EFC” model should look when mounted correctly on the wall.
Refer to the U.L. rating label on the front cover of the unit to verify the unit is an
“EFC” model before continuing.
Any
other mounting configuration will prevent the unit from operating properly.
If the unit is mounted correctly and still does not produce hot water, look to see if the
indicator light illuminates when the hot water faucet is fully opened.
If the indicator light illuminates, turn to page 5.
If the indicator light does not illuminate, turn to page 3
All other possible situations turn to page 6.
