Hydrogen gas is extremely flammable and explosive.

To prevent the possibility of injury under these con-
ditions, we recommend the hot water faucet be

opened for several minutes at the kitchen sink
before any electrical appliances which are connected

to the hot water system are used (such as a dish-
washer or washing machine). If hydrogen gas is pre-

sent, there will probably be an unusual sound stmi-
lar to air escaping through the pipe as the hot water

faucet is opened. There must be no smoking or open
flame near the faucet at the time it is open.

AWARNING

Due to the nature of the typical gas water heater,
the water temperature in certain situations may be

hotter than the thermostat setting.

Short, frequent draws of hot water - especially with

very cold incoming water - can shock the thermo-
stat into brief operation resulting in hotter and hot-

ter layers of water closer to the top of the tank.
Changes in hot water usage patterns or raising the
temperature differential between the cut-on of the
thermostat and the cold water temperature will
usually eliminate the problem.
