• The thermostat(s) on this water
heater have been factory set to
approximately 120°F to reduce the
risk of scalding. Higher temperatures
increase the risk of scalding, but
even at 120°F, hot water can scald.
If you choose a higher temperature,

at each point-of-use are par cularly
important to help avoid scalding.
