The RHEEM as-58728-01 is an exhaust transition assembly designed for use in RHEEM heating and cooling equipment. This component connects the exhaust pathway between internal combustion or heat exchange sections and the venting system, directing combustion byproducts safely out of the unit. It is a direct OEM replacement part, intended for installation by licensed HVAC technicians performing service or equipment restoration. The assembly weighs 1 pound, making it a compact but essential part of a properly functioning exhaust train.
This exhaust transition assembly is suited for residential and light commercial RHEEM systems where the exhaust pathway requires repair or replacement due to damage, corrosion, or deterioration. It fits within the machine assembly category, indicating use as a functional internal component rather than an accessory. Technicians encountering exhaust leaks, venting failures, or unit error codes related to combustion airflow should evaluate this part as part of their diagnostic process.
Designed as an OEM-style replacement exhaust transition assembly for RHEEM heating and cooling equipment requiring restoration of the exhaust pathway.
Installation should be performed by a licensed HVAC technician. Power down the unit at the disconnect and allow the heat exchanger and exhaust components to cool completely before beginning service. Inspect surrounding venting and flue connections for damage while the assembly is accessible. Follow all applicable local mechanical codes and manufacturer service documentation when reinstalling exhaust components.
