Installation (Water Connections) continued-
This water heater can deliver scalding temperature water at any faucet in the
system. Be careful whenever using hot water to avoid scalding injury. Certain
appliances such as dishwashers and 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, the
potential for scald injury increases. To protect against injury, you should
install an ASSE approved mixing 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 manufacturer of this water
heater or a local
plumbing supplier. Please consult with a plumbing
professional.

WARNING
Hydrogen gas can be produced in an operating water heater that
has not had water drawn from the tank for a long period of time
(generally two weeks or more). Hydrogen gas is extremely
flammable. To prevent the possibility of injury under these
conditions, we recommend the hot water faucet to be open for
several minutes at the kitchen sink before you use any electrical
appliance, which is connected to the hot water system. If
hydrogen is present, there will be an unusual sound such as air
escaping through the pipes as hot water begins to flow. Do not
smoke or have open flame near the faucet at the time it is open.
