Fireye 35-69 Heat Insulator 320734-701 What is the purpose ofThe Fireye 35 69 Heat Insulator is a critical thermal barrier designed for high heat industrial burner environments. This 1 2" NPT heat insulator is specifically engineered to protect Fireye 48PT and Fireye UV1A flame detectors from convective and conductive heat transfer. By decoupling the scanner from the sight pipe, the 35 69 prevents sensor overheating, which is the leading cause of premature failure in ultraviolet flame scanners and infrared
