The Imperial 36017 Thermocouple helps ensure safe and reliable gas appliance operation by accurately sensing flame presence. This 18" thermocouple with an M10 nut is designed to fit compatible equipment, generating a small electrical signal when heated by the pilot flame. It works by sending this signal to the gas valve, allowing it to remain open only when a flame is detected. If the flame goes out, the signal stops and the gas supply is shut off. Its dependable performance supports safety, helps prevent gas leaks, and maintains consistent operation in commercial kitchen equipment.
