This Velocity Boiler Works Condensate Trap/Flame Sense Harness is a critical component designed for use in heating systems. The condensate trap, part of the harness, is engineered to collect and dispose of acidic condensation produced during the combustion process, thereby preventing corrosion within the boiler system. The flame sense portion of the harness is responsible for detecting and confirming the presence of a flame in the burner assembly. If no flame is detected, it sends a signal to shut down fuel supply, ensuring safe operation. This product is compatible with specific models of boilers manufactured by Velocity Boiler Works and should be installed by a qualified professional to ensure proper function and safety.
