ICP Gas Valve Support Bracket for RGS121HDBA0AAAA — OEM Mount | Ships Today

Overview

This is the OEM gas valve support bracket (OEM 1178238) for the ICP / Tempstar / Heil RGS121HDBA0AAAA gas furnace. The bracket rigidly mounts and supports the gas valve and manifold assembly inside the burner compartment, holding the valve in proper alignment with the gas line and burner orifices. A missing, bent, or corroded bracket lets the valve and manifold flex under the weight of the piping, which can stress the gas connection threads and throw off burner alignment. This is the correct factory support hardware for a clean, code-compliant gas valve installation.
