The Goodman 0128F00006 is a genuine OEM chimney transition bottom built for DMP100-42AA gas furnaces and compatible Goodman/Amana models. This sheet-metal transition channels hot flue gases from the furnace's induced-draft assembly toward the vent/chimney connection, forming a properly sized, leak-resistant path for combustion byproducts. A corroded, cracked, or mismatched transition can allow flue-gas leakage or draft problems — making this an important part to keep in factory spec.
The OEM Goodman 0128F00006 is formed to the precise dimensions and mounting hole pattern of the DMP100 vent path, ensuring a tight, correctly aligned seal. Generic or hand-fabricated transitions risk gaps, misalignment, and improper draft, which can compromise venting safety. For flue components, genuine OEM fit is essential.
Moderate. Replacement involves removing screws at the induced-draft outlet and vent connection, then resealing per code. Allow 30–45 minutes. Ensure power and gas are off, and verify proper draft after installation. Professional installation recommended for any flue/venting work.
