This Lochinvar sensor is designed to monitor the temperature of flue gases in heating systems. The device, known as a Flue Sensor, is engineered to ensure optimal performance and safety by detecting abnormal rises in temperature that could indicate potential issues. It operates within a temperature range of -40┬░F to 392┬░F (-40┬░C to 200┬░C), providing accurate readings under various operating conditions. The sensor is compatible with select models of Lochinvar boilers and water heaters, allowing for versatile use across multiple appliances. Constructed from robust materials, it offers durability and reliability for long-term use.
