Adjusting the Water Heater Thermostat
Water heater thermostat is factory set to its
lowest temperature. This may or may not be
suitable for your needs.
Turn thermostat knob clockwise to
increase water temperature.
Turn thermostat knob counter-clockwise
to decrease water temperature.
Studies have indicated that dangerous bac-
teria, including legionella, pneumophila, can
form in the potable water distribution sys-
tem if certain minimum water temperatures
are not maintained. Contact your local
health department for more information.
• Check water temperature at a hot water faucet
immediately after first heating cycle. Further
temperature adjustment may be necessary as
water heating system is used. Recheck water
temperature at faucet after adjustment.
• When adjusting thermostat, be sure boiler limit
control is set a minimum of 20ºF higher.
