ICP Gas Valve Support Bracket for RGS120HDAA0AGAA — OEM Mounting Hardware | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part number 1178238) for the ICP / Heil / Tempstar RGS120HDAA0AGAA gas furnace. The bracket secures the gas valve assembly to the furnace burner box, holding the valve in correct alignment with the manifold and burner tubes so that gas flow, manifold pressure, and burner ignition all stay within spec. While it carries no electrical or gas rating of its own, it is a critical structural component: a missing, cracked, or corroded bracket allows the gas valve and manifold to sag or vibrate, which can crack flare fittings, stress the pilot/igniter assembly, and cause intermittent flame faults. Technicians most often replace this bracket after a valve swap, after corrosion damage in high-humidity installs, or when retrofitting a replacement gas valve that shipped without mounting hardware.

Specifications

Compatibility

Designed as a direct-fit replacement for the RGS120HDAA0AGAA furnace and shares fitment across the RGS120 family and closely related ICP-built Heil, Tempstar, and Comfortmaker gas furnace platforms that use the same burner box layout. Always confirm against your unit's parts diagram before ordering.

Installation Guide

1. Safety First — Shut off the gas supply at the manual valve and disconnect electrical power. Verify zero voltage at the control board with a multimeter.
2. Access — Remove the furnace front service panel to expose the burner/manifold assembly.
3. Document — Photograph the gas valve, manifold, and bracket orientation before removing anything.
4. Remove — Disconnect the gas line union at the valve, unscrew the manifold/valve from the old bracket, then remove the bracket fasteners from the burner box.
5. Install — Mount the new bracket in the same orientation, refit the gas valve and manifold, and torque fittings to spec.
6. Test — Restore gas and power, then leak-check every joint with soap solution and confirm a clean burner ignition.

Signs You Need a Replacement

• Visible cracking, bending, or rust-through on the existing bracket
• Gas valve or manifold that sags, shifts, or vibrates during operation
• Recurring flare-fitting gas leaks at the valve
• Bracket missing from a replacement gas valve kit
