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.
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, you may
create the potential for scald injury. 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.
