CA Health & Safety Code Section 108525

A warning label shall be affixed near the thermostat of all new water heaters to be sold in the state for residential use. This warning shall read as follows: “Warning: Setting of the water heater thermostat in excess of 130 degrees Fahrenheit or 54 degrees centigrade may cause accidental scalding or other injury, particularly to children or elderly persons.” The Legislature does not intend by the enactment of this section to impose any duty on public utilities to affix this warning label or otherwise warn their customers relative to existing water heaters.
