ICP Gas Valve Support Bracket for RGS121HFBB0AAAA — OEM Mounting Bracket | Ships Today

Overview

This OEM gas valve support bracket, part number 1178238, mounts and stabilizes the gas valve assembly inside the ICP Tempstar/Heil RGS121HFBB0AAAA gas furnace. The bracket holds the valve in proper alignment with the manifold and burners, preventing strain on the gas piping and reducing vibration that can loosen fittings over time. A bent, corroded, or missing bracket can allow the valve to shift, stressing the gas line connections and creating a potential leak point. This direct-fit replacement restores secure, factory-correct mounting.

Installation Guide

1. Safety First — Shut off the gas supply, disconnect power at the breaker, and verify zero voltage with a multimeter.

3. Document — Photograph the valve, bracket position, and gas line routing before disassembly.
4. Remove — Support the gas valve, unfasten the old bracket from the cabinet and valve, and set the valve safely aside without stressing the piping.
5. Install — Position the new bracket, refasten it to the cabinet and valve, and confirm proper alignment with the manifold.
6. Test — Restore gas and power, leak-check all joints with soap solution, and run a heat cycle to verify safe operation.
