Overview
This is the genuine OEM gas valve support bracket (part number 1178238) for the ICP / Heil / Tempstar RGS121HFAB0AAAA gas furnace. The bracket secures the gas valve in its correct position inside the burner compartment, holding it rigid against the manifold and gas piping so that vibration, thermal cycling, and normal handling during service do not stress the valve body or its threaded connections. A loose or missing bracket is a common cause of gas-line stress fractures, intermittent valve chatter, and nuisance flame-rollout trips. Replacing a corroded, bent, or missing bracket restores the factory mounting geometry and keeps the valve aligned with the burner assembly.

Installation Guide
- Safety First — Shut off the gas supply and disconnect electrical power. Verify zero voltage with a multimeter and confirm gas is off.
- Access — Remove the furnace burner/blower access panel.
- Document — Photograph the gas valve, bracket position, and wiring before disturbing anything.
- Remove — Loosen the gas valve mounting hardware and remove the old or damaged bracket. Support the valve so the gas piping is not stressed.
- Install — Position the new bracket per your photo, fasten it to the cabinet, and re-secure the gas valve to the bracket.
- Test — Restore gas and power, leak-check all joints with soap solution, and verify a clean ignition and burner light-off.
Signs You Need a Replacement
- Gas valve moves or vibrates against the manifold during operation
- Visible rust, cracking, or bending of the original bracket
