Energy Cut Out (ECO)
An automatic gas shut-off device (ECO) is incorporated in the sensor and control board which will shut off gas
supply to the burner if the water heater temperature exceeds 207°F (97.2°C). Should the ECO function (open),
the water temperature should be reduced to approximately 120°F (49°C) and follow applicable Lighting
Instructions to place the water heater in operation. The water heater must have the problem corrected by a
qualified service person before putting the water heater back in operation. It is recommended that all service
work be performed by a qualified service agency.
If the water heater is to remain idle for 30 days or more or is subjected to freezing temperatures while shut off,
the water heater and piping should be fully drained (see To Drain the Water Heater) and the drain valve should
be left fully open.
NOTICE
In the event of an emergency, turn OFF the gas and electric to the appliance. The water heater should be
inspected at a minimum annually by a qualified service technician for damaged components and/or joints not
sealed. DO NOT operate this water heater if any part is found damaged or if any joint is found not sealed.
WARNING
Water heaters are heat producing appliances. To avoid damage or injury there must be no materials stored
against the water heater or vent system, and proper care must be taken to avoid unnecessary contact
(especially by children) with the water heater and vent system. UNDER NO CIRCUMSTANCES SHOULD
FLAMMABLE MATERIALS, SUCH AS GASOLINE OR PAINT THINNER BE USED OR STORED IN THE
VICINITY OF THIS WATER HEATER, VENT SYSTEM OR IN ANY LOCATION FROM WHICH FUMES
COULD REACH THE WATER HEATER OR VENT SYSTEM.
