Specifications

In order for a Series 100 Flame Guard® water heater to

operate, the pilot must be lit. The heat from the pilot

ame creates an

electrical current in the thermopile. The

thermopile generates the power needed to operate the

electronic gas control without requiring an external power

source.

The electronic gas control incorporates an LED status

indicator with advanced self diagnosc features. The elec-

tronic Gas Valve monitors the operaon of the heater and

will ash an error code if it idenes an issue.

A temperature limit switch or ECO (Energy Cut O) sensor

located in the gas control valve is used to shut o the

water heater if the water temperature exceeds 189°F

(87°C) for 155°F models or 199°F (93°C) for 180°F models.

Gas Water Heater Operation

Insucient combuson air supply or blocked venlaon

can also acvate the thermal cuto switch. When these

condions have been corrected, the thermal switch can

be reset.
