WATER TEMPERATURE ADJUSTMENT
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.
WARNING
SCALDING
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.
