Utica-Dunkirk 19292 Flame Rollout Switch 350°F

The Utica-Dunkirk 19292 Flame Rollout Switch is a security regulation part in gas-fired air conditioning and heating systems such as boilers and furnaces. It is built to detect abnormal flame conditions where heat or combustion gases escape outside the burner area. When the temperature at the switch reaches approximately 350F, it opens the circuit and shuts down the system to prevent fire hazards or equipment damage. It is mounted near the burner assembly or combustion chamber and used in heating units during installation to ensure safe ignition and operation under fault conditions.
