Install Instructions

IS-210-5
Series LF210-5 / 210-5
Temperature Gas Shutoff Valves
This Shutoff is an emergency device and will operate only when water temperature
approaches a maximum safe level of approximately 210°F. When it shuts off the gas to
the burner, some trouble with the operating controls is indicated. The heater installation
should be checked by a qualified service technician or licensed plumbing contractor
before being put back into service.
After operating from high temperature, the Shutoff must be manually reset (opened).
This is done by pressing on the “Reset” button, pushing it in as far as it will go (see
instructions below). Tank water temperatures must cool several degrees before valve
can be reset after operating. If, after pressing reset button, valve does not stay open
allowing gas to flow to the burner, insufficient cooling of the water is the probable
cause.
This Gas shutoff should be installed so that the temperature sensing element is located in the
water within the upper 6" of the tank.
