ICP Gas Valve Support Bracket for RGS121LSBB0AAAA | Ships Today

Overview

This OEM gas valve support bracket (part 1178238) fits the ICP / Tempstar / Heil RGS121LSBB0AAAA gas furnace. The bracket rigidly mounts and supports the gas valve and manifold assembly inside the burner compartment, holding the valve in the correct position relative to the burners and isolating it from vibration and stress on the gas piping. A bent, corroded, or missing bracket lets the valve and manifold flex, which can stress threaded gas connections, misalign the burners, and create a potential leak or ignition problem. Installing the correct OEM bracket restores proper, secure mounting and keeps the gas train safely aligned.
