Utica-Dunkirk 14631303 Vent Temperature Switch 180°F

The Utica-Dunkirk 14631303 Vent Temperature Switch is a temperature monitoring component used in boilers and direct vent heating equipment to detect elevated vent or inducer temperatures during operation in HVAC systems. It is used to activate at 180F, and it helps to protect the venting and combustion system by interrupting burner operation when excessive heat conditions occur. It is used in gas-fired boiler assemblies and induced draft systems, and it operates as part of the appliance control circuit and avoids overheating caused by restricted airflow, vent blockage, or combustion irregularities in the system.
