The flue sensor wires are essential for connecting the flue gas temperature or pressure sensor to the control board of your boiler or burner. These wires transmit critical data that the system uses to monitor combustion efficiency and safety. Damaged or corroded wires can cause false readings, shutdowns, or inefficient operation. Replacing them with this set ensures accurate signal transmission and reliable performance. Designed to withstand high temperatures and harsh conditions, these wires are a common spare part for heating equipment maintenance. Keep your system running safely and efficiently with proper flue sensor wiring.
