4.2 Kubatanidza Mafuta
Connect the fuel lines as follows:
- Inlet (Suction) Line: Connect the fuel supply line to the designated inlet port. Ensure a tight, leak-free connection.
- Nozzle Line (Pressure): Connect the line leading to the burner nozzle to the pressure port (marked 'P' on some models).
- Return Line: If applicable, connect the return line to the return port (marked 'V' on some models) to send excess fuel back to the tank. For single-pipe systems, the return port must be plugged.
4.3 Kubatanidzwa kweMagetsi
Connect the pump's electrical terminals to the burner control system according to the burner manufacturer's wiring diagram. Ensure correct voltage and polarity. All electrical work must comply with local codes and regulations.
4.4 Kugadzira Pombi
After installation, the pump must be primed to remove air from the fuel lines. This is typically done by running the burner for a short period until a steady flame is established. Some pumps may have a bleed screw for manual air removal.
5. Operating Instructions
Once installed and primed, the DANFOSS BFP 21R3 pump operates automatically in conjunction with the burner control system. The pump maintains the required fuel pressure for efficient combustion.
5.1 Kugadzirisa Kudzvinyirira
The pump's pressure can be adjusted via a pressure regulating screw, typically located on the pump body. Use a pressure gauge to set the desired operating pressure as specified by the burner manufacturer. Turn the screw clockwise to increase pressure and counter-clockwise to decrease pressure.
6. Kuchengeta
Regular maintenance ensures optimal performance and extends the life of the pump.
6.1 Routine Checks
- Inspect fuel lines for leaks, cracks, or damage.
- Check electrical connections for tightness and corrosion.
- Listen for unusual noises during operation, which may indicate a problem.
6.2 Kutsiva Sefa
The pump typically contains an internal filter that should be inspected and replaced periodically, usually annually or as recommended by the burner manufacturer. A clogged filter can restrict fuel flow and reduce pump performance.
