ICP Gas Valve Support Bracket for RGS121HDAB0AAAA — OEM Mount | Ships Today

Overview

This OEM gas valve support bracket (part number 1178238) is the factory mounting hardware that secures the gas valve assembly inside the ICP/Tempstar/Heil RGS121HDAB0AAAA furnace. The bracket rigidly anchors the valve to the manifold and cabinet so the gas line, valve body, and burner manifold stay in precise alignment. A bent, corroded, or missing support bracket lets the valve flex under the weight of the gas piping, which stresses the threaded connections and can lead to leaks or a misaligned manifold. Replacing the bracket restores the correct factory geometry and keeps the valve solidly mounted.

Installation Guide

1. Safety First — Shut off the gas supply, disconnect power, and verify zero voltage with a multimeter.
2. Access — Remove the burner compartment service panel.
3. Document — Photo the bracket orientation and valve position before loosening anything.
4. Remove — Support the gas valve, then unfasten the old bracket from the cabinet and valve body.
5. Install — Mount the new 1178238 bracket, reattach the valve, and confirm the manifold alignment matches your photo.
6. Test — Restore gas and power, leak-check all joints with soap solution, and verify a clean ignition cycle.
