whenever using hot water to avoid scalding injury.
automatic clothes washers may require increased temperature water. By setting the thermostat on this
water heater to obtain the increased temperature water required by these appliances, you may create the
potential for scald injury. To protect against injury, you should install a tempering valve in the water
system. This valve will reduce point of discharge temperature by mixing cold and hot water in branch
supply lines. Such valves are available from the local plumbing supplier.
Test the temperature of the water with your elbow before placing a child in the bath or shower. Do not
leave a child or an infirm person in the bath unsupervised.
