ICP Gas Valve Support Bracket for RGS121SEBB0AAAA — OEM Mounting Bracket | Ships Today

Overview

This OEM gas valve support bracket (part number 1178238) mounts and stabilizes the gas valve within the ICP/Heil/Tempstar RGS121SEBB0AAAA furnace manifold assembly. The bracket holds the valve in proper alignment with the manifold and burner assembly, preventing strain on the gas piping and maintaining correct positioning for safe, leak-free operation. A bent, corroded, or missing bracket can allow the valve to shift, stressing threaded gas connections and risking a leak. Replacing it with the genuine OEM bracket restores factory alignment and secure mounting.

3. Document — Photograph the bracket, valve orientation, and gas piping routing before disassembly.
4. Remove — Support the gas valve, remove the fasteners securing the old bracket, and detach it from the valve and chassis.
5. Install — Position the new bracket, fasten it to the chassis, and secure the valve in its original alignment.
6. Test — Restore gas, leak-check all connections with a bubble solution, restore power, and verify a normal heating cycle.
