ICP Gas Valve Support Bracket for RGS121SRAB0AAAA | Ships Today

Overview

This is a genuine OEM gas valve support bracket (part number 1178238) for the ICP/Tempstar/Heil RGS121SRAB0AAAA gas furnace. Note: this listing is for the mounting bracket that supports the gas valve, not the gas valve itself. The bracket holds the gas valve and manifold securely in position so the burner alignment and gas piping connections stay stable through thermal cycling and vibration. A bent, corroded, or broken support bracket can let the gas valve and manifold shift, stressing the gas line connections and affecting burner alignment.
