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 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 water begins to flow. THERE SHOULD BE NO SMOKING OR
OPEN FLAME NEAR THE FAUCET AT THE TIME IT IS OPEN.
