The Southbend 1182154 Range Thermopile provides a reliable source of millivolt power for gas range safety systems. This component is a two-lead, 36-inch thermopile designed to convert heat from a pilot flame into electrical energy, generating between 250 and 750 millivolts to operate gas valves without external power. It works by using multiple thermocouples connected in series to produce a steady electrical output when heated. This ensures consistent performance in maintaining pilot operation and gas flow control. Its durable construction and extended lead length support flexible installation, while reducing downtime and supporting safe, efficient equipment operation in commercial kitchen environments.
