Section V 5-3 Automatic Water Fill (Optional)
When this option is ordered, an electric water solenoid valve and various fittings required is
installed on the rear of the heater. It will also require a cold water supply line run to the
heater.
The electric water valve is mounted on a 1/4” nipple in the upper right corner on the rear of
the heater.
This will leave 1/2” hookup. When hooking up your domestic water supply make sure a
cutoff valve is installed and flexible connections to remove the screen for annual cleaning.
See illustration below.
