AWARNING

HYDROGEN GAS: Hydrogen gas can be produced in

a hot water system that has not been used for a

long period of time (generally two weeks or more).

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 simi-

lar to air escaping through the pipe as the hot water

faucet isopened. There must be no smoking or open

flame near the faucet at the time it is open.

_,WARNING

INSULATING JACKETS: When installing an external

water heater insulation jacket on a gas water heater:

• DO NOT cover the temperature-pressure relief valve.

• DO NOT put insulation over any part of the top of

the gas water heater.

• DO NOT put insulation over the gas control valve or

gas control valve/burner cover, or any accessareas

to the burner.

• DO NOT let insulation around the gas water heater

to get within 8 inches of the floor (air must get to

the burner).

• DO NOT cover or remove operating instructions,

and safety related warning labels and materials

affixed to the water heater.

Failure to heed this will result in the possibility of a

fire or explosion.
