The BRADFORD WHITE BW-239-44078-00 is an inner door gasket kit designed to seal the combustion chamber door on Bradford White water heaters. The gasket creates a reliable barrier between the burner door assembly and the heater body, preventing combustion gas leakage and maintaining proper draft and efficiency. This is a direct replacement service part installed by licensed plumbers and HVAC technicians during routine maintenance or when the existing gasket shows signs of deterioration, compression failure, or heat damage.
This inner door gasket kit is suited for residential water heater service applications. It is typically installed during burner door removal and reassembly, making it a standard component to replace whenever the combustion chamber is accessed for inspection or burner service. Keeping the door gasket in good condition is essential to safe heater operation and proper venting performance.
Designed as an OEM-style replacement inner door gasket kit for Bradford White residential gas water heaters requiring part number BW-239-44078-00.
Installation should be performed by a licensed plumber or qualified HVAC technician. Before beginning work, shut off the gas supply and allow the water heater to cool completely. Inspect the door flange surface for warping or debris before seating the new gasket, and ensure the burner door is reassembled evenly to achieve a proper seal. Refer to local codes and the appliance service manual for torque and reassembly guidance.
