WARNING
Hydrogen gas can be produced in a hot water system served by this
water 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.
CAUTION
INCREASING THE THERMOSTAT SETTING ABOVE THE PRESET
TEMPERATURE MAY CAUSE SEVERE BURNS AND CONSUME
EXCESSIVE ENERGY. HOTTER WATER INCREASES THE RISK OF
SCALD INJURY.
