Overview
This is the genuine OEM gas valve support bracket (part 1178238) for the ICP / Tempstar / Heil RGS121HDAA0AAAA gas furnace. The bracket rigidly mounts and supports the gas valve and manifold assembly inside the burner compartment, holding the valve in correct alignment with the burners and gas supply line. A properly secured gas valve resists vibration, prevents stress on the gas piping connections, and maintains the precise burner-to-manifold geometry the furnace was designed around. A bent, corroded, or missing bracket allows the valve to sag or vibrate, which can stress fittings, cause gas leaks, or misalign the burners.

- Access — Remove the burner compartment service panel.
- Document — Photograph the gas valve, manifold, and bracket orientation before removing anything.

- Install — Fit the new bracket, fasten it securely, and confirm the gas valve sits in its original aligned position.
- Test — Restore gas and power, then leak-test all gas connections with soap solution and verify normal burner ignition.
