Overview
This is the OEM gas valve support bracket (factory part number 1178238) for the ICP/Tempstar/Heil RGS121HTCB0AAA gas furnace. The bracket anchors the gas valve to the burner assembly, keeping the valve and its inlet/outlet gas connections rigid and properly aligned during operation. When the bracket is loose, corroded, or damaged, the gas valve can shift under vibration — stressing the gas piping, loosening unions, and potentially causing nuisance lockouts. Installing a fresh bracket during a gas valve service restores secure mounting and protects the new valve from movement-related wear.

Installation Guide
- Safety First — Shut off the gas at the manual valve and disconnect power; verify zero voltage with a multimeter.
- Access — Remove the furnace burner-compartment service panel.
- Document — Photograph the gas valve, bracket position, and gas piping before disconnecting.
- Remove — Disconnect the gas line unions as needed, remove the fasteners holding the old bracket, and detach it from the valve and chassis.
- Install — Mount the new bracket in the original position, fasten to the chassis, and reattach the gas valve so connections align without strain.
- Test — Restore gas, leak-check all joints, restore power, and verify a normal heating cycle.
Signs You Need a Replacement

- Visible cracks, bending, or corrosion on the existing bracket.
