If your Riello oil burner isn’t firing right, the hydraulic jack might be worn out. This small jack (part #7001039 or C7001039) is designed for Riello F3, F5, F10, and F15 series burners. It’s a critical component that helps regulate fuel flow and pressure. Replacing it can fix issues like poor ignition, fluctuating flame, or burner lockouts. Make sure to match the part number with your old unit. Installation requires some technical knowledge—if you’re not comfortable, get a pro. Keep your heating system running efficiently with a genuine Riello-compatible part. Essential for maintenance or repair on residential or light commercial oil burners.
