ICP Gas Valve Support Bracket for RGS120LFAB0AAA — OEM Mount | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part 1178238) for the ICP/Tempstar/Heil RGS120LFAB0AAA gas furnace. The bracket rigidly mounts the gas valve and manifold assembly inside the burner compartment, holding the valve in correct alignment with the burners and supporting the weight of the gas piping. Proper bracket support is critical for safe combustion: if the valve sags or shifts, manifold-to-burner spacing changes, gas-train connections are stressed, and slow gas leaks or misaligned flames can develop. Installers commonly need this bracket when the original is bent, corroded, or was removed during a gas valve replacement and not reused. Symptoms of a failed or missing bracket include a gas valve that moves when touched, strained or kinked gas tubing, rattling from the burner box during operation, and difficulty achieving a clean manifold-to-burner alignment.

Specifications

Compatibility

Designed for the ICP RGS120LFAB0AAA gas furnace and related Tempstar, Heil, Comfortmaker, and ICP models that use this factory gas valve mounting arrangement. Verify your manifold and valve orientation match before installing.

Installation Guide

1. Safety First — Shut off the gas supply at the manual shutoff and disconnect electrical power. Verify zero voltage with a multimeter and confirm no gas flow.
2. Access — Remove the furnace burner/service panel to reach the gas valve and manifold.
3. Document — Photograph the bracket position, gas line routing, and valve orientation before disturbing anything.
4. Remove — Support the gas valve, disconnect or loosen the manifold/valve fasteners as needed, and remove the old bracket.
5. Install — Mount the new bracket, secure the gas valve and manifold to it in the original orientation, and snug all fasteners.
6. Test — Restore gas and power, leak-check every joint with soap solution, and verify clean burner ignition and flame.

Signs You Need a Replacement

• Gas valve moves or sags when touched
• Bent, cracked, or corroded original bracket
• Strained, kinked, or misaligned gas tubing at the manifold
