ICP Gas Valve Support Bracket for RGS120LSAA0AAA — OEM Mounting Bracket | Ships Today

Overview

This is the OEM gas valve support bracket (part number 1178238) for the ICP / Tempstar / Heil RGS120LSAA0AAA gas furnace. The bracket secures the gas valve to the burner assembly, holding it in correct alignment with the manifold and burner orifices. A loose, corroded, or damaged bracket lets the gas valve shift, which can strain the manifold pipe joint, cause vibration noise, and in severe cases create a gas-tight-seal concern at the valve inlet. Replacing a worn or bent bracket restores proper valve positioning and keeps the burner assembly rigid.

Installation Guide

1. Safety First — Shut off the gas supply and disconnect electrical power. Verify zero voltage with a multimeter.
2. Access — Remove the furnace burner-compartment door.
3. Document — Photograph the gas valve, bracket, and manifold orientation before disturbing anything.
4. Remove — Loosen the manifold/valve connections only as needed, then remove the screws holding the old bracket and lift it out.
5. Install — Position the new bracket, fasten it, and reseat the gas valve so the manifold aligns with the burners.
6. Test — Leak-check all gas joints with soap solution, restore power and gas, and verify a clean burner ignition.

Signs You Need a Replacement

• Visible rust, cracks, or bending in the existing bracket
• Gas valve that wobbles or shifts on the manifold
