ICP Gas Valve Support Bracket for RGS120LRAA0AGAA — OEM Mount | Ships Today

Overview

This OEM gas valve support bracket (P/N 1178238) for the ICP / Tempstar / Heil RGS120LRAA0AGAA holds the furnace gas valve in its correct position within the burner assembly. A solid mount keeps the valve aligned with the manifold and gas piping, preventing strain on the inlet/outlet connections and reducing the risk of gas leaks from stressed fittings. A bent, corroded, or missing bracket lets the valve sag or vibrate, which can loosen pipe joints and cause intermittent ignition or service-call repeat visits. This bracket is a direct OEM replacement that restores factory mounting integrity.

Specifications

Compatibility

Designed for the ICP RGS120LRAA0AGAA gas furnace and shared across many ICP-family models marketed under Tempstar, Heil, Comfortmaker, and Arcoaire that use the same burner/manifold layout. Confirm your valve mounting pattern against the old bracket before installing.

2. Access — Remove the burner compartment service panel.
3. Document — Photograph the gas valve, bracket, and wiring orientation before removing anything.
4. Remove — Disconnect the gas line unions and valve wiring, then unfasten the old bracket from the chassis.
5. Install — Mount the new bracket, secure the gas valve to it, and reconnect the gas piping and wiring per your photo.
6. Test — Restore gas and power, leak-check all joints with soap solution, and confirm a normal ignition cycle.
