5780 Electrode Insulator Assembly Z2000 Setting Gauge and 51304 Trans Former Gasket Replacement Kit Compatible with Beckett AF/AFG/SF/SR and AFII Oil Burners
【Compatibility】The 5780 electrode insulator assembly, Z2000 gauge and 51304 gasket are compatible with Beckett AF/AFG/SF/AR/SR and AFII burners. A single installation restores ignition timing, air-fuel ratio and static pressure to factory standards in one go.
【Product Advantages】Made from high-quality materials and heat-resistant 95% alumina, electrode insulator assembly maintains stable performance in high-temperature environments, prevents high-voltage tracking, and eliminates ignition failures and equipment lock-outs.
【Optimize Burner Performance】The oil burner setting gauge enables precise positioning of both the electrodes and the nozzle, ensuring rapid ignition on the first attempt. The exact air-fuel ratio produces a perfect flame, cutting carbon build-up, smoke and fuel consumption.
【Pressure Seal】The 51304 trans former gasket fills the gap between the ignition transformer and the housing, preventing static-pressure loss, eliminating start-up rumble and flame-out risk, and allowing the burner to ignite quietly and stably even in low-temperature or high-load conditions.
【Oil Burner Replacement Kit】The oil burner replacement kit for Beckett integrates three functions—insulation, positioning and sealing—into one unit. A single installation simultaneously renews electrode insulation, electrode/nozzle positioning and transformer-base sealing, quickly restoring factory-level combustion performance and reducing carbon build-up.
