Rheem SP20305A – OEM Pilot Assembly Kit for Natural Gas Water Heaters
The Rheem SP20305A is a factory-specified pilot assembly kit for natural gas-fired residential water heaters. Designed for use with specific Rheem, Ruud, and Richmond FVIR (Flammable Vapor Ignition Resistant) models, this assembly provides a stable pilot flame for burner ignition and includes a thermocouple for integrated safety shutoff. It is a direct-replacement component used in systems requiring restoration of pilot ignition functionality due to wear, fouling, or failure of the original assembly.
Primary Functions
Maintains a continuous pilot flame to initiate burner operation
Includes a thermocouple that monitors flame presence and shuts off gas if ignition fails
Supports sealed combustion systems in FVIR-rated units
