ICP Gas Valve Support Bracket for RGS120HSAA0AAA — OEM Mounting Bracket | Ships Today

Overview

This genuine OEM gas valve support bracket (PN 1178238) for the ICP/Tempstar/Heil RGS120HSAA0AAA gas furnace holds the gas valve and manifold rigidly in place inside the burner compartment. A secure bracket keeps the valve correctly aligned with the manifold and burner orifices, preventing strain on the gas piping and maintaining proper burner flame geometry. A cracked, bent, or corroded bracket lets the valve sag or vibrate, which can stress threaded gas connections, cause manifold misalignment, and create the conditions for a gas leak or rough ignition. Replacing a damaged support bracket during a valve or manifold service ensures the assembly is mounted to factory spec.

Specifications

Compatibility

Designed for the ICP/Tempstar/Heil RGS120HSAA0AAA gas furnace and related ICP-family models that share the same burner box and gas valve mounting layout. Verify your bracket geometry against the original before installing.

Installation Guide

1. Safety First — Shut off the gas supply at the manual shutoff, disconnect electrical power at the breaker, and verify zero voltage with a multimeter.
2. Access — Remove the furnace burner compartment service panel.
3. Document — Photograph the gas valve, manifold, and bracket orientation before disturbing any connections.
4. Remove — Disconnect the gas line union, unbolt the old bracket, and lift out the valve/manifold assembly as needed.
5. Install — Mount the new support bracket, reattach the gas valve and manifold, and reconnect the gas line per your photo.
6. Test — Restore gas and power, leak-test all joints with soap solution, and confirm clean burner ignition.

Signs You Need a Replacement

• Bent, cracked, or rusted bracket allowing the gas valve to sag or wobble.
• Visible strain or misalignment at the manifold and gas piping.
• Rattling or buzzing from the burner compartment during operation.
• Repeated rough ignition traced to a loose valve mount.
