Hydrogen Gas Flammable

Explosion Hazard

Flammable hydrogen gases may be present.

Keep all ignition sources away from faucet when turning on hot water.

Hydrogen gas can be produced in a hot water system served by this appliance 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 a hot water faucet served by this appliance 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 at the time it is open.

Verify the power to the water heater is turned off before performing any service procedures.

Water temperature over 125°F (52°C) can cause severe burns instantly resulting in severe injury or death.

Children, the elderly and the physically or mentally disabled are at highest risk for scald injury.

Feel water before bathing or showering.

Temperature limiting devices such as mixing valves must be installed when required by codes and to ensure safe temperatures at fixtures.

Explosion Hazard

Overheated water can cause water tank explosion.

Properly sized temperature and pressure relief valve must be installed in the opening provided.

CAUTION

Improper installation, use and service may result

in property damage.
