ICP Gas Valve Support Bracket for RGS121LFBB0AAAA — OEM Mounting | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part 1178238) for the ICP / Tempstar / Heil RGS121LFBB0AAAA gas furnace. The bracket rigidly mounts the gas valve to the burner manifold assembly, keeping the valve aligned and preventing stress on the gas line connections. A missing, bent, or corroded bracket allows the gas valve to sag or vibrate, which can loosen pipe joints, create small gas leaks, and put strain on the valve body and inlet/outlet fittings. Replacing the bracket during a gas valve service ensures the new valve sits square and the manifold geometry stays correct.

Specifications

Compatibility

Direct OEM fit for the ICP-built RGS121LFBB0AAAA furnace and related Tempstar, Heil, and Comfortmaker models using the same manifold and gas valve mounting layout. Verify the bolt-hole pattern against your existing bracket.

Installation Guide

1. Safety First — Shut off the gas supply at the manual valve, disconnect power, and verify zero voltage with a multimeter. Ventilate the area before working near gas connections.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the bracket position, valve orientation, and all gas line routing before disconnecting.
4. Remove — Disconnect the gas valve as needed, unbolt the old bracket from the manifold/cabinet.
5. Install — Mount the new bracket, reattach the gas valve, and torque the gas fittings to spec. Reconnect per your photo.
6. Test — Restore gas and power, then leak-check every joint with soap solution and confirm proper ignition.

Signs You Need a Replacement

• Gas valve sagging, tilted, or vibrating loose on the manifold
• Bent, cracked, or heavily corroded bracket
