ICP Gas Valve Support Bracket for RGS121HSAB0AAAA — OEM Mount | Ships Today

Overview

This is the genuine OEM gas valve support bracket (OEM 1178238) for the ICP / Tempstar / Heil RGS121HSAB0AAAA gas furnace. Please note: this is the mounting bracket that holds the gas valve in position, not the gas valve assembly itself. The bracket rigidly anchors the gas valve to the burner assembly and manifold so that gas-line connections stay aligned and stress-free during operation and service. A bent, cracked, or missing bracket lets the valve and manifold shift, which can strain the gas piping joints and create the conditions for a leak. Replacing a damaged bracket restores the correct, factory-specified gas valve alignment.

2. Access — Remove the furnace burner-compartment door.
3. Document — Photograph the gas valve, bracket, and piping orientation before loosening anything.
4. Remove — Support the gas valve, unfasten it from the old bracket, and remove the damaged bracket.
5. Install — Mount the new bracket, refasten the gas valve, and confirm the manifold and piping are aligned and unstressed.
6. Test — Restore gas, leak-check all joints with soap solution, then restore power and verify normal ignition.
