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.
