ICP Gas Valve Support Bracket for RGS121HECA0AAA — OEM Mounting Bracket | Ships Today

Overview

This OEM gas valve support bracket (part 1178238) is the factory mounting bracket that secures the gas valve and manifold assembly inside the ICP Tempstar / Heil RGS121HECA0AAA gas furnace. The bracket holds the valve in correct alignment with the burner manifold so the orifices stay properly indexed to the burners, and it isolates the valve from cabinet vibration that can stress the gas piping and threaded fittings. A bent, corroded, or cracked bracket can allow the valve to shift, causing manifold misalignment, gas leaks at the union, or rattling during operation. Replacing a damaged bracket restores a safe, rigid mount for the gas train.

Installation Guide

1. Safety First — Shut off the gas supply at the manual shutoff, disconnect power, and verify zero voltage with a multimeter.
2. Access — Remove the burner/service panel.
3. Document — Photograph the gas valve, bracket, and manifold orientation before loosening anything.
4. Remove — Support the valve, disconnect it from the manifold if required, and unbolt the old bracket.
5. Install — Fasten the new bracket, remount the valve in its original position, and reseal any gas joints with approved pipe dope.
6. Test — Restore gas and power, leak-check all joints with bubble solution, and confirm a clean burner light-off.
