ICP Gas Valve Support Bracket for RGS121LEBB0AAAA – OEM Mounting | Ships Today

Overview

This is the OEM gas valve support bracket (part number 1178238) for the ICP / Tempstar / Heil RGS121LEBB0AAAA gas furnace. The bracket holds the gas valve in its correct position within the burner compartment, maintaining proper alignment between the valve, the manifold, and the burner assembly. Correct support prevents stress on the gas line and manifold threads, keeps the valve from vibrating loose, and ensures the burners receive an even, properly aligned gas supply. A bent, corroded, or missing bracket can allow the valve to shift, leading to manifold strain, gas leaks, or improper burner flame patterns.

Specifications

Compatibility

Made to fit the burner/manifold assembly on the ICP-family RGS121LEBB0AAAA furnace and the equivalent Tempstar, Heil, and Comfortmaker models built on the same chassis. Confirm bracket part number 1178238 against your existing component before ordering.

Installation Guide

1. Safety First — Shut off the gas supply, disconnect electrical power, and verify zero voltage with a multimeter.
2. Access — Remove the burner compartment door to reach the gas valve and manifold.
3. Document — Photograph the bracket position and valve orientation before disassembly.
4. Remove — Disconnect the gas line union if required, then unfasten the old bracket from the valve and cabinet.
5. Install — Mount the new bracket, reattach the gas valve in its factory position, and reconnect the gas line.
6. Test — Restore gas and power, leak-check all joints with soap solution, and verify a clean, even burner flame.

Signs You Need a Replacement

• Gas valve that moves, sags, or vibrates in the burner compartment.
