FOR YOUR SAFETY
Increasing the wattage and/or voltage from the factory original
equipment can require changes to the water heater and/or the
electric service. Unauthorized modification of the water heater may
create a hazard to life and property and will nullify the warranty.
Contact your dealer or utility company before making any changes.
