“AIR” IN HOT WATER FAUCETS

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 ﬂ ammable and

explosive. To prevent the possibility of injury under these conditions,

we recommend the hot water faucet, located farthest away, be

opened for several minutes before any electrical appliances which are

connected to the hot water system are used (such as a dishwasher

or washing machine). If hydrogen gas is present, there will probably

be an unusual sound similar to air escaping through the pipe as the

hot water faucet is opened. There must be no smoking or open ﬂ ame

near the faucet at the time it is open.

SAFETY SHUT OFF SYSTEM

This water heater is designed to automatically shut off in the event

of the following:

1. When the pilot flame is extinguished for any reason.

A thermocouple is used to determine if a pilot ﬂ ame is present

and will shut off the gas supply to the main burner and pilot if

the ﬂ ame is absent.

2. When the water temperature in the tank exceeds 189°F (87°C).

The gas control valve\thermostat includes a temperature

limiting ECO (Energy Cut Off) system that activates when

excessive water temperatures are present. If this occurs, the

system cannot be reset. The gas control valve/thermostat

must be replaced.
