ICP Gas Valve Support Bracket for RGS120HSAA0AGAA | Ships Today

Overview

This is the genuine OEM gas valve support bracket, part number 1178238, for the ICP / Heil / Tempstar RGS120HSAA0AGAA gas furnace. The bracket bolts to the furnace cabinet and the manifold/gas-valve assembly, holding the gas valve rigidly in place so the manifold, burner orifices, and gas line stay in precise alignment. A solid mount prevents stress on the gas piping and keeps burner orifices correctly positioned over the burners – critical for clean ignition and a stable flame. Note: this is the support bracket only, not the gas valve itself.

Specifications

Compatibility

Built for the ICP RGS120HSAA0AGAA 120,000 BTU gas furnace and shared across related ICP-manufactured Heil, Tempstar, and Comfortmaker RGS-series furnaces using the same manifold layout. Verify the bracket profile against your existing part before installing.

Installation Guide

1. Safety First – Shut off the gas supply, disconnect electrical power, and verify zero voltage with a multimeter.
2. Access – Remove the burner-compartment service panel.
3. Document – Photograph the bracket, manifold, and gas-valve orientation before removal.
4. Remove – Disconnect the manifold as needed, then unbolt the old bracket from the cabinet.
5. Install – Fasten the new bracket, remount the gas valve/manifold, and confirm orifice-to-burner alignment.
6. Test – Restore gas and power, leak-check all joints with soap solution, and verify smooth ignition.
