Weil-mclain 591-126-618 Burner Manifold Size 8

Product Description

The WEIL-MCLAIN 591-126-618 is a Size 8 burner manifold designed for use in cast iron gas boilers. The manifold distributes gas to the burner sections of the boiler, providing a consistent and controlled fuel supply across the burn area. Measuring 15.00 x 2.96 x 8.33 inches, this manifold is a direct OEM-style replacement component installed by licensed plumbers and heating technicians during routine service or component-level repairs on residential and light commercial heating systems.

This burner manifold is intended for use in WEIL-MCLAIN CGi, CGa-5, and CGi-5 series boilers. It is suited for natural gas-fired hydronic heating applications where the original manifold requires replacement due to wear, corrosion, or damage. Installation typically occurs during a boiler section repair or burner assembly service call.
