ICP Gas Valve Support Bracket for RGS121LSAB0AAAA — Steel Mount | Ships Today

Overview

This OEM gas valve support bracket (1178238) secures and stabilizes the gas valve assembly inside the ICP / Tempstar / Heil RGS121LSAB0AAAA furnace. The bracket ties the valve body to the burner manifold so the gas piping, valve, and manifold stay rigidly aligned, preventing stress on the threaded connections that could lead to a gas leak. Over time these brackets can corrode, bend, or go missing after a gas valve replacement, leaving the valve unsupported and the manifold flexing during firing cycles. Installing the correct factory bracket restores proper, code-compliant support for the gas train.

Specifications

Compatibility

Built for the ICP RGS121LSAB0AAAA gas furnace and shared-platform Tempstar, Heil, and Comfortmaker models using the same gas valve and manifold layout. Verify your OEM part number against the unit before ordering.

Installation Guide

1. Safety First — Shut off the gas supply, disconnect power, and verify zero voltage with a multimeter.
2. Access — Remove the burner/service panel to reach the gas valve and manifold.
3. Document — Photograph the bracket orientation and fastener locations before removal.
4. Remove — Unbolt the old bracket from the valve and manifold; support the valve so it does not hang on the gas line.
5. Install — Position the new bracket, fasten it to the manifold and valve body, and confirm the valve sits square with no strain on the piping.
6. Test — Restore gas and power, leak-check all joints with soap solution, and verify normal burner operation.

Signs You Need a Replacement

• Gas valve flexes or hangs loose on the manifold
• Corroded, cracked, or bent support bracket
• Bracket missing after a prior gas valve repair
• Stress or movement at the manifold threaded joints during firing
