ICP Gas Valve Support Bracket for RGS120HTAA0AGAA — OEM 1178238 | Ships Today

Overview

This is the OEM gas valve support bracket (part number 1178238) for the ICP / Tempstar / Heil RGS120HTAA0AGAA gas furnace. The bracket secures the gas valve to the burner assembly and maintains correct alignment of the valve, manifold, and burner orifices. A loose, corroded, or damaged bracket can allow the gas valve to shift, stressing the manifold pipe joint and creating the potential for misaligned flames or a gas leak at the union. This is a structural mounting component — it is not the gas valve itself.

Specifications

Compatibility

Designed for the ICP Tempstar Heil RGS120HTAA0AGAA furnace. ICP-built equipment shares components across the Tempstar, Heil, Comfortmaker, and Arcoaire lines — verify the part number 1178238 against your unit's parts breakdown before ordering, as bracket geometry varies by manifold size.

Installation Guide

1. Safety First — Shut off the gas supply at the manual shutoff valve and disconnect electrical power. Verify zero voltage with a multimeter.
2. Access — Remove the furnace front service panel to expose the burner and gas valve assembly.
3. Document — Photograph the bracket orientation and any attached wiring or tubing before disturbing it.
4. Remove — Disconnect the gas valve from the manifold if required, then remove the screws securing the old bracket to the burner box.
5. Install — Mount the new bracket in the same orientation, refasten the gas valve, and reconnect the manifold. Apply approved pipe sealant to gas joints.
6. Test — Restore gas and power, then leak-check every joint with electronic detector or bubble solution and confirm normal burner ignition.

Signs You Need a Replacement

• Gas valve sits loose or shifts when touched
• Visible rust, cracking, or deformation of the bracket
• Stress or hairline cracks at the manifold pipe joint
