The RUUD RXGW-C01 is a 4-inch flue adapter kit designed to connect venting components in residential and light commercial gas heating systems. This kit provides the mechanical transition needed to join flue pipe sections or to adapt a furnace or water heater flue outlet to a compatible venting assembly. Licensed HVAC technicians and gas fitters install this component as part of a complete venting system upgrade or appliance replacement. The 4-inch diameter matches common B-vent and single-wall metal flue configurations found in standard residential installations.
This flue adapter kit is suited for use with gas-fired furnaces and water heaters that require a 4-inch flue connection. It is typically installed during equipment changeouts, venting repairs, or system upgrades where the existing vent connector must be adapted to a new appliance outlet or to a different venting product in the same system. Proper flue adapter selection is essential for maintaining draft performance and safe combustion gas routing.
Designed as an OEM-style flue venting accessory for RUUD gas-fired heating equipment requiring a 4-inch flue adapter connection.
Installation should be performed by a licensed HVAC technician or qualified gas fitter in accordance with the appliance manufacturer instructions and applicable local codes including the International Fuel Gas Code (IFGC). Always shut down the appliance and allow all components to cool before beginning any venting work. Ensure all flue joints are properly secured and sealed per the venting system manufacturer requirements to prevent combustion gas leakage. Do not mix venting system types or materials unless explicitly approved by the appliance and venting manufacturers.
