ICP Gas Valve Support Bracket for RGS121LFCA0AAA — OEM Mount | Ships Today

Overview

This OEM gas valve support bracket (part 1178238) for the ICP Tempstar Heil RGS121LFCA0AAA gas furnace holds the gas valve rigidly in place on the manifold assembly. The bracket prevents the valve and gas line from flexing under vibration, which protects the manifold threads and pilot/igniter alignment and helps maintain a leak-free gas seal. A bent, corroded, or missing support bracket allows the valve to sag or shift, stressing the gas connections and potentially causing a hazardous leak. This exact-fit replacement restores factory mounting geometry for the gas train.

3. Document — Photo the gas valve, bracket, and wiring orientation before removal.
4. Remove — Loosen the bracket fasteners and free the old support without straining the gas line.
5. Install — Position the new bracket, secure the gas valve to it, and tighten all fasteners per your photo.
6. Test — Restore gas and power, leak-check all joints with soap solution, and verify normal ignition.
