Overview
This is the OEM gas valve support bracket (factory part number 1178238) for the ICP/Tempstar/Heil RGS121LDAA0AAAA gas furnace. The bracket secures the gas valve to the furnace burner assembly, holding it in the correct alignment so the inlet and outlet gas connections stay rigid and leak-free during operation. A loose, corroded, or damaged bracket lets the gas valve shift under vibration, which can stress gas piping, loosen unions, and trigger nuisance lockouts. Replacing a worn bracket during a gas valve service restores secure mounting and protects the new valve from movement-related failures.

Installation Guide
- Safety First — Shut off the gas supply at the manual valve and disconnect electrical 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 anything.
- Remove — Disconnect the gas line unions as needed, remove the fasteners holding the old support bracket, and detach it from the valve and chassis.
- Install — Mount the new bracket in the original position, refasten to the chassis, and reattach the gas valve so connections align without strain.
- Test — Restore gas, leak-check all joints with approved solution, restore power, and verify a normal heating cycle.
Signs You Need a Replacement
- Gas valve shifts or rattles during furnace operation.
- Visible cracks, bending, or heavy corrosion on the existing bracket.
