CAUTION
Hydrogen gas is produced by this heater in a hot water
system that has not been used for a long period of time
(2 weeks or more). Hydrogen gas is extremely fl amma-
ble. 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.
When hydrogen is present, there will probably be an
unusual sound such as air escaping through the pipe as
the water begins to fl ow. There should be no smoking or
open fl ame near the faucet at the time it is open.
