ICP Gas Valve Support Bracket for RGS121LTAB0AAAA — OEM Mounting Bracket | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part #1178238) for the ICP / Heil / Tempstar RGS121LTAB0AAAA gas furnace. The bracket bolts inside the burner compartment and rigidly supports the gas valve and the manifold/gas-train assembly, preventing strain on the pipe threads and keeping the valve correctly aligned with the burners. A bent, corroded, or missing bracket lets the gas valve sag, which can stress the gas piping joints and create a potential leak path. This is a structural component only — it does not include the gas valve itself.

Compatibility

Designed for the ICP/Heil/Tempstar RGS121LTAB0AAAA gas furnace and related RGS121 series units using the same manifold layout. Confirm the bracket profile against your existing part before ordering.

Installation Guide

1. Safety First — Shut off the gas supply and disconnect electrical power; verify zero voltage with a multimeter.
2. Access — Remove the burner-compartment service panel.
3. Document — Photograph the gas valve, manifold, and bracket orientation before disconnecting anything.
4. Remove — Support the gas valve, remove the screws securing the old bracket, and lift out the damaged bracket.
5. Install — Position the new bracket, fasten it to the cabinet, and re-secure the gas valve/manifold so the assembly is level and unstrained.
6. Test — Restore gas and power, leak-test all joints with a bubble solution, and verify normal ignition and burner operation.

Signs You Need a Replacement

• Gas valve sags or is not securely held in place.
• Bracket is bent, cracked, or rust-perforated.
