Why this pilot lid is useful Restores pilot ignition function quickly when the original pilot lid or burner assembly is damaged or causing ignition problems. Saves time on repairs by swapping a single assembly instead of diagnosing multiple components. Dual fuel readiness reduces parts purchases when switching between natural gas and propane. Key features Direct fit: designed as a dropin replacement for OEM 002003F with compatibility across the listed heater models. Easy installation: 1/4 inch compression fitting, Btype bracket, and righthand pilot assembly allow quick swap without modifications or special tools. Materials: stainless steel components combined with heatresistant plastic resist rust and deformation under normal operating conditions. Precision nozzle: 0.18 mm gas nozzle promotes a steady flame and helps reduce pilot outages, ignition failures, and flame sensor errors. Dual fuel ready: includes two nozzle sizes with a propane orifice so the same assembly can be used for natural gas or propane conversions.
