ICP Gas Valve Support Bracket for RGS120HDCA0AAA — OEM Mounting | Ships Today

Overview

This OEM gas valve support bracket (part 1178238) for the ICP / Tempstar / Heil RGS120HDCA0AAA furnace secures and aligns the gas valve to the burner manifold and furnace base. The bracket maintains the correct height and angle of the valve so the manifold-to-valve threads stay leak-tight and the valve body is not stressed by the weight of the connected gas line. A bent, corroded, or missing support bracket can let the gas valve sag, putting strain on pipe joints and risking a gas leak or misaligned burners. This is the factory mounting component — not the gas valve itself — and is the correct repair part when the original bracket is damaged during service or rusted through.

Installation Guide

1. Safety First — Shut off the gas supply and disconnect power at the breaker. Verify zero voltage with a multimeter before working near the valve.
2. Access — Remove the furnace burner-compartment service panel.
3. Document — Photograph the bracket position, gas line routing, and wiring before disassembly.
4. Remove — Disconnect the gas line and valve wiring, unbolt the old bracket, and separate it from the valve.
5. Install — Mount the gas valve to the new bracket, secure the bracket to the furnace base, and reconnect the gas line and wiring per your photo.
6. Test — Restore gas and power, then leak-check every joint with soap solution and confirm proper ignition.
