Goodman B2526004 6-Burner Gas Manifold

The Goodman B2526004 is a genuine OEM six-burner gas manifold built for the GMPN120-5 120,000 BTU gas furnace. The manifold is the pre-drilled fuel rail that carries gas from the valve and distributes it evenly across all six burner orifices. Precise orifice spacing and drilling are critical for a stable, uniform flame — an aftermarket or damaged manifold can cause uneven ignition, roll-out, or improper BTU delivery. This factory part is machined to Goodman's exact gas-flow specification.

Specifications

OEM Part Number: B2526004
Configuration: 6-burner manifold
Compatibility: Goodman GMPN120-5 (120K BTU) gas furnace
Function: Distributes gas evenly to all burner ports
Fitment: Pre-drilled, exact-fit fuel rail

OEM vs. Generic

OEM guarantees correct orifice bore diameter, thread pitch, and burner spacing. Generic manifolds rarely match the drilling pattern of a 120K unit and can dangerously alter the gas mixture. For a combustion component, OEM is strongly recommended.

Installation Difficulty

Moderate (3/5). Requires shutting off gas, disconnecting the gas valve union, removing burners, and swapping the manifold. A gas-leak test after reassembly is mandatory. Best performed by an experienced DIYer or licensed HVAC technician.
