Series LF210-5 automatic gas shutoff valves are positive-acting energy shutoff for the emergency temperature protection of gas water heaters. They are self-contained devices independent of all other operating controls. They provide protection against overheating water in the domestic hot water supply heating systems by automatically shutting off the gas supply to the heater in the event that the water temperature reaches 210°F (99°C). Series LF210-5 must be manually reset in order to resume heater service. This feature serves as a warning of malfunctioning of the normal operating controls. Manual resetting is easily done and does not require dismantling or replacing of any part of the valve. See Reset Button feature. The LF210-5 features Lead Free construction to comply with Lead Free installation requirements. This gas shutoff differs from other contemporary design in that Watts engineers have embodied the time tested Watts auto-thermatic thermal actuator principle along with a snap-acting trip latch which closes the valve at a definite controlled temperature. Models LFL210-5 M2, LFLL210-5 M2 and LFLLL210-5 M2 feature extended shanks for up to 2 inch thick insulation for use with the new generation of water heaters containing extra thick insulation.
