ICP Gas Valve Support Bracket for RGS121SRBA0AAAA — OEM Mount | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part number 1178238) for the ICP / Heil / Tempstar RGS121SRBA0AAAA gas furnace. The bracket rigidly mounts and supports the gas valve within the burner compartment, holding it in correct alignment with the manifold and absorbing vibration so the gas connections stay leak-free over the life of the furnace. A bent, corroded, or missing bracket lets the gas valve and manifold shift, which can stress the gas line joints and cause leaks or misaligned burner flames.

Specifications

Compatibility

Factory replacement for the ICP/Heil/Tempstar RGS121SRBA0AAAA and related RGS-series gas furnaces using the same burner/manifold layout. The bracket is model-specific to ensure correct gas valve alignment — verify the part number against your furnace before installing.

Installation Guide

1. Safety First — Shut off the gas supply and disconnect power, then verify zero voltage with a multimeter.
2. Access — Remove the furnace burner/service panel.
3. Document — Photograph the gas valve, manifold, and bracket position before disassembly.
4. Remove — Disconnect the gas line and unbolt the gas valve, then remove the old support bracket.
5. Install — Mount the new bracket, refit the gas valve in proper manifold alignment, and reconnect the gas line.
6. Test — Restore gas, leak-check every joint with soap solution, then restore power and verify normal burner ignition.

Signs You Need a Replacement

• Bent, cracked, or corroded bracket.
