Overview
The Fireye 4-314-1 UV tube is a high-sensitivity ultraviolet sensing component designed for use in Fireye flame scanner assemblies. This tube detects ultraviolet radiation produced by an active flame and transmits a signal to associated scanner electronics in boiler burner controls, flame-monitoring systems, and heating equipment. Supplied as a discrete replacement component, the 4-314-1 is an internal sensing element—not a housing or complete assembly.
Key Features
- Ultraviolet flame detection for reliable burner ignition confirmation
- Direct replacement for compatible 45UV series Fireye scanners
- Compact design (2.95″ × 1.9″ × 1.75″) for internal scanner installation
- Optimized for Engineering Code 6 and higher scanner revisions
- Lightweight sensing tube (0.05 lb) for minimal system impact
