The Raypak 006021F Roll-Out/Flue Sensor 150°F is a safety control device designed to monitor excessive heat around the burner and flue areas of compatible gas-fired HVAC equipment. Calibrated to activate at 150°F, it detects abnormal temperature conditions caused by blocked vents or flame roll-out and interrupts the burner circuit to help prevent unsafe operation. Commonly used in Raypak boilers, pool heaters, and commercial water heating systems, this sensor enhances system safety, protects critical components from heat damage, supports reliable performance, and helps extend equipment lifespan through dependable over-temperature protection.
