ICP Gas Valve Support Bracket for RGS121HSCB0AAA — OEM Mounting Kit | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part #1178238) for the ICP/Tempstar/Heil RGS121HSCB0AAA gas furnace. The support bracket secures the combination gas valve to the burner assembly, holding it in proper alignment with the manifold and burner orifices. A loose, corroded, or bent bracket allows the gas valve to shift, which can misalign the burner flame, create vibration noise, and stress the gas line connections. Using the factory-correct bracket ensures the valve sits at the exact height and angle the manufacturer specified, preserving safe combustion and proper flame impingement.
