Rheem SP20063 Gasket Kit – Burner Door Gasket Replacement for FVIR Gas Water Heaters

The Rheem SP20063 is an OEM burner access door gasket replacement kit for use with select Rheem, Ruud, Richmond, and GE FVIR (Flammable Vapor Ignition Resistant) gas water heaters. This kit is required any time the burner assembly is removed for inspection, maintenance, or replacement, and is designed to maintain the combustion chamber seal to original factory standards.

The gasket is constructed from high-temperature silicone and engineered to provide a reliable thermal and gas-tight barrier between the combustion chamber and the exterior of the heater. Replacing the gasket is critical for preserving appliance efficiency, meeting safety requirements, and preventing flue gas leakage.

Compatible Models

This gasket kit is compatible with multiple 30, 40, and 50-gallon FVIR gas water heaters manufactured under the Rheem, Ruud, Richmond, and GE brands. Always verify compatibility against the unit’s model number or consult OEM documentation.

Installation Considerations

Professional installation is recommended. The burner compartment must be properly sealed to maintain combustion safety and efficiency. After installation, the appliance should be checked for proper draft and combustion performance per local code and manufacturer requirements. Failure to install the gasket properly may result in unsafe operating conditions.
