The RESIDEO 50041888-002 is a large bypass duct with an integrated manual damper, designed for use with the TrueEASE HE200 basic flow-through humidifier. Measuring approximately 14-7/8 inches in length, this bypass duct routes conditioned air through the humidifier during heating cycles. The manual damper allows the technician to control airflow through the bypass, making it easy to shut off humidifier bypass flow during the cooling season. HVAC technicians install this component as part of a complete humidifier installation or as a direct replacement for a damaged or missing bypass duct assembly.
This bypass duct is intended for residential forced-air HVAC systems where the TrueEASE HE200 flow-through humidifier is installed. It mounts between the supply plenum and the humidifier, creating the bypass loop that draws warm supply air across the water panel. The manual damper built into the duct body gives the installer direct control over seasonal airflow without the need for a separate external damper component.
Designed for use with the TrueEASE HE200 basic flow-through humidifier as specified by the manufacturer.
Installation should be performed by a licensed HVAC technician. Before servicing or replacing the bypass duct, shut down the furnace and humidifier and set the thermostat to the off position. Ensure the duct is properly sealed at all connection points to prevent air leakage. Refer to the HE200 installation manual for duct routing requirements and damper position guidance for heating and cooling seasons.
