CAUTION: Hydrogen gas can be produced in a hot water system served by this water heater that has not been used for a

gas and to reduce risk of injury, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink

such as air escaping through the pipe as the water begins to flow. Do not smoke or use an open flame near the faucet at the
time it is open.

power circuit to the heating element.
Once the control opens, it must be
reset manually.
