ICP Gas Valve Support Bracket for RGS121SFAA0AAAA — OEM Mounting | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part 1178238) for the ICP / Tempstar / Heil RGS121SFAA0AAAA gas furnace. The bracket rigidly mounts the gas valve to the burner assembly, holding it square to the manifold and absorbing vibration so the valve's inlet and outlet connections stay leak-free over the life of the unit. A bent, corroded, or missing bracket lets the gas valve sag or twist, which stresses the manifold pipe joints and can create a gas leak or misaligned burners. If you are replacing a gas valve or repairing burner-area corrosion, fitting a sound support bracket is essential to a safe, code-compliant install.

Installation Guide

1. Safety First — Shut off the gas supply and disconnect power, then verify zero voltage with a multimeter.
2. Access — Remove the burner-compartment service panel.
3. Document — Photograph the gas valve, manifold, and bracket orientation before removal.
4. Remove — Disconnect the gas line union and valve wiring, unbolt the old bracket from the burner box.
5. Install — Bolt the new bracket in place, remount the gas valve square to the manifold, and reconnect the gas line using fresh pipe dope on threaded joints.
6. Test — Restore gas and power, then leak-check every joint with soap solution and confirm clean burner ignition.

Signs You Need a Replacement

• Gas valve sagging, tilted, or visibly unsupported
