WATER TEMPERATURE ADJUSTMENT
This water heater can deliver scalding temperature water at any
faucet in the system. Be careful whenever using hot water to
avoid scalding injury. By setting the thermostat on this water
heater to obtain an increased water temperature, you may create
the potential for scald injury. To protect against injury, you
should install an ASSE approved mixing valve (a device to limit
the temperature of water to protect against scald injury via
mixing hot and cold water supply) in the water system. This
valve will reduce point of discharge temperature in branch supply
lines. Such valves are available from the manufacturer of this
water heater or a local plumbing supplier. Please consult with a
plumbing professional.
Table 8 details the approximate relationship of water temperature
and time with regard to scald injury and may be used as a guide in
determining the safest water temperature for your applications.
Water temperature over 125°F
can cause severe burns
instantly or death from scalds.
Children, disabled and elderly
are at highest risk of being
scalded.
Review this instruction manual
before setting temperature
at water heater.
Feel water before bathing or
showering.
Temperature limiting valves are
available.
