OPERATION & SERVICE
Heating Element Ratings
There are six “standard” heating element KW ratings used; 3, 6, 9,
12, 15 and 18KW. Heating element flanges are stamped with the part
number, voltage and KW rating - see the illustration to the right.
Heating Element Configurations
The table below shows standard heating element configurations
used. Keep in mind the water heaters covered by this service manual
can be custom ordered with heating element voltage and KW ratings
other than what is shown in this table. Always check the water
heater’s rating label to see how the water heater was configured at the factory.
Service Note: Models at 54 KW and above are not available in 208 single phase (1Ø)
configurations. Also notice that some 208 volt models will contain additional elements.
