WARNING: 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 2 weeks or more). Hydrogen gas is extremely flammable.
To reduce the risk of injury under these conditions, it is recommended that a hot water faucet be
opened for several minutes 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 when it is initially opened.
