IMPORTANT SAFETY INFORMATION READ ALL INSTRUCTIONS BEFORE USING
DANGER!
WATER TEMPERATURE SETTING
Safety and energy conservation are factors to be considered when selecting the
water temperature setting. Water temperatures above 125°F can cause severe
burns or death from scalding. The thermostat is adjusted to its lowest temperature
position when shipped from the factory. Be sure to read and follow the warnings
outlined on the label pictured below.
The chart shown above may be used as a guide in
determining the proper water temperature for your
home.
DANGER: Households with small children, disabled,
or elderly persons may require a 120°F. or lower
temperature setting to prevent contact with”HOT” water.
Maximum water temperature occurs while burner is on.
To nd water temperature being delivered, turn on a hot
water faucet and place a thermometer in the water stream
and read the thermometer.
The temperature of the water at the outlet of the water
heater can be regulated by setting the temperature on the
control panel. The control panel was set at 110°F before it
was shipped from the factory.
The illustration to the bottom left illustrates the control
panel and how to adjust the water temperature.
NOTICE: When this water heater is supplying general
purpose hot water requirements for use by individuals, a
thermostatically controlled mixing valve for reducing point
of use water temperature is recommended to reduce the
risk of scald injury. Contact a licensed plumber or the local
plumbing authority for further information.
NOTICE: The factory setting allows operating temperatures
between 80°F and 140°F.
NOTICE: This is an automatic temperature controlled
tankless water heater. This means that the temperature
must be set from the front LED control panel. You
can restrict the ow of the incoming water using the
built in ow restrictor in order to achieve a desired set
temperature. This tankless water heater is ow activated
and will adjust gas ames to heat water as necessary.
