Setup and Installation
The Riello 40 G3B Oil Pump (Part Number 20031996) is designed for use with Riello 40 G3B, G5, and G10 burners. It is compatible with gas oil, kerosene, and a 20% blend of biofuel.
Pre-Installation Checks:

- Inspect the pump for any signs of damage during shipping.
- Ensure all necessary tools and fittings are available.
Installation Steps:
- Disconnect Power: Turn off the main power supply to the burner and heating system.
- Remove Old Pump (if applicable): Carefully disconnect fuel lines and mounting bolts from the existing pump. Be prepared for fuel spills and have absorbent materials ready.
- Mount New Pump: Secure the Riello 40 G3B pump to the burner assembly using appropriate fasteners. Ensure a stable and vibration-free mounting.
- Connect Fuel Lines: Attach the fuel supply and return lines to the designated ports on the pump. Ensure all connections are tight and leak-free. Refer to the burner's specific diagram for correct port identification.

Operating Instructions
The Riello 40 G3B Oil Pump is an automatic pump designed to supply fuel to the burner at the required pressure. Its operation is integrated with the burner's control system.
- Automatic Operation: The pump activates and deactivates automatically in response to the burner's demand for fuel.
- Pre-ventilation Safety Feature: The pump incorporates a safety feature that prevents pressure in the hydraulic circuit during the pre-ventilation phase of the burner cycle. This ensures safe ignition.
- Fuel Compatibility: Ensure that the fuel being used (gas oil, kerosene, or up to 20% biofuel blend) is appropriate for both the pump and the burner system.
For detailed operational sequences, refer to the specific instruction manual for your Riello burner model.
Maintenance
Regular maintenance is crucial for the reliable operation and longevity of your Riello oil pump. Always ensure the power supply is disconnected before performing any maintenance.
- Fuel Filter Replacement: Periodically check and replace the fuel filter (if applicable to your system) to prevent contaminants from reaching the pump. Consult your burner manual for recommended intervals.
- System Inspection: Annually inspect all fuel lines and connections for leaks, cracks, or signs of wear. Tighten any loose connections.
- Nozzle Cleaning/Replacement: While not directly part of the pump, a clean nozzle is essential for efficient fuel delivery. Follow burner manufacturer guidelines for nozzle maintenance.
- Professional Service: It is recommended to have the entire heating system, including the oil pump, serviced annually by a qualified technician.
