Honeywell 129464M UV Sensing Tube 0–250°F

The Honeywell 129464M UV Sensing Tube is a critical safety component for gas-fired furnaces and boilers in HVAC systems. It acts as an alert observer, picking up ultraviolet (UV) light released during regular combustion. When variations in UV levels are detected by this sensor tube, the flame detector is triggered, which then turns off the gas supply to avert any dangers like explosions. This essential part, which can operate between 0 and 250 degrees Fahrenheit, is compatible with a variety of Honeywell HVAC systems, guaranteeing the safe and dependable operation of your heating system. It is essential to replace the UV-detecting tube regularly following the manufacturer's instructions to preserve maximum performance and security.
