This is how your “ES” model should look when mounted correctly on the wall.
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

If the indicator light illuminates, turn to page 6.
If the indicator light does not illuminate, turn to page 3.
Other possible situations turn to page 7.
