A pilot flame heat is used on a gas range thermopile in commercial cooking equipment to generate a small electrical output. This signal is used for ignition systems and safety valves in gas appliances. It provides a 250-750mV output and a 36" 2-lead configuration to pass the signal from the burner area to the control system. The bulb section detects flame heat and converts it into usable electrical power for millivolt systems. This component is frequently found in restaurant kitchen cooking equipment, kitchen heating units, and gas cooking appliances. It is intended for long-term use in kitchen environments where constant ignition is required. The long lead supports installation in different equipment layouts. When the thermopile becomes weak or fails to produce enough voltage to ignite the burner, replacing it can help restore normal ignition and reduce burner interruptions during operation.
