PART 4 – HEATER WIRING
Tank must be full of water before power is turned on. Heating elements will be damaged if energized for even a short time while tank is
dry. Failures due to “dry-firing” are NOT covered by warranty.
This unit is factory wired to a junction box on top of the water heater for field wiring connection. These heaters are equipped and wired
for the maximum possible input allowable (see Table 2 for listing of inputs and amperage requirements). The voltage requirement and
dedicated wattage load for the heater is specified on the rating label of the water heater. Consult your local power company to
determine if your electrical service is adequate for the additional load of the heater.
Refer to the wiring diagrams below for field connections. All wiring must conform to local code and the National Electric Code, and
should be done by a qualified licensed electrician or the local electric utility. Grounding can be accomplished by using approved conduit
and fittings or other approved conductive material. A grounding wire is provided on the junction bracket. This grounding wire must be
used in the installation.
