GENERAL SAFETY INFORMATION
HYDROGEN GAS (FLAMMABLE)
Hydrogen gas can be produced in a hot water system served
by this heater that has not been used for a long period of time
(generally two weeks or more). Hydrogen gas is extremely
flammable. To reduce the risk of injury under these conditions, it
is recommended that the hot water faucet be opened for several
minutes at the kitchen sink before using any electrical appliance
connected to the hot water system. If hydrogen is present there
will probably be an unusual sound such as air escaping through
the pipe as the water begins to flow. THERE SHOULD BE NO
SMOKING OR OPEN FLAME NEAR THE FAUCET AT THE TIME
IT IS OPEN.
3
Water temperature over 125°F (52°C)
can cause severe burns instantly
resulting in severe injury or death.
Children, the elderly and the
physically or mentally disabled are at
highest risk for scald injury.
Feel water before bathing or
showering.
Temperature limiting devices such as
mixing valves must be installed
when required by codes and to
ensure safe temperatures at fixtures.
