4. Setup and Installation
Proper installation of the nozzle and electrode assembly is critical for the safe and efficient operation of your oil burner. Follow these steps carefully:
- Determine Firing Rate: Before proceeding, determine the proper firing rate for your boiler or furnace unit. This involves considering the specific application and selecting the appropriate nozzle and pump pressure to achieve the required heat output from the burner. Consult your burner's primary manual for guidance on firing rate determination.
- Remove Existing Nozzle Adapter: If replacing an existing component, carefully remove the nozzle adapter from the drawer assembly by loosening the retaining screw.
- Insert New Nozzle: Insert the correct nozzle into the nozzle adapter. Ensure it is seated properly and tighten securely. Do not overtighten, as this can damage the nozzle or adapter.
- Replace Adapter Assembly: With the new nozzle installed, replace the nozzle adapter assembly into the burner's drawer assembly. Secure it firmly with the retaining screw.
- Set Electrode Position: Use the Irnyso Red Gauge Electrode Setting Gauge to accurately set the electrode gap and placement from the nozzle. This tool helps position the electrodes at the proper angle relative to the nozzle's spray angle, which is essential for efficient ignition. Refer to the operating instructions in Section 5 for detailed guidance on using the gauge.

5. Operating Instructions (Electrode Setting)
The Irnyso 3006965 gauge is designed to simplify the precise adjustment of oil burner electrodes. Accurate electrode positioning is crucial for reliable ignition and optimal combustion.
- Identify Electrode Position: Locate the electrodes within the burner assembly. These are typically positioned near the nozzle.
- Place the Gauge: Carefully place the red gauge over the nozzle and electrodes. The gauge is designed to fit snugly, guiding the electrodes into their correct positions.
- Adjust Electrodes: Gently adjust the electrodes until they align with the markings or contours of the gauge. The gauge provides the correct gap and angle relative to the nozzle's spray pattern. This ensures the ignitor spark occurs at the optimal point for fuel atomization and ignition.
- Verify Settings: Once adjusted, carefully remove the gauge and visually inspect the electrode positions. Ensure they are stable and maintain the set gap and angle.
- Test Burner: After all adjustments are made, perform a test firing of the burner according to the manufacturer's instructions to confirm proper operation and ignition.
Note: If you are unsure about any step, it is recommended to consult a qualified HVAC technician.
6. Maintenance
The Irnyso Red Gauge Electrode Setting Gauge is a durable tool. To ensure its longevity and accuracy:
- Store the gauge in a clean, dry place when not in use.
- Avoid dropping or subjecting the gauge to excessive force, which could affect its calibration.
- Clean the gauge with a soft, dry cloth if it becomes dirty. Do not use harsh chemicals.
Regular maintenance of your oil burner system, including periodic inspection of nozzles and electrodes, is recommended to maintain efficiency and prevent issues.
7. Troubleshooting
This section addresses common issues related to electrode and nozzle setup. If you encounter problems after using the setting gauge, consider the following:
- No Ignition or Delayed Ignition: This could indicate an incorrect electrode gap or position. Re-check the electrode settings using the gauge and ensure they are firmly in place. Also, verify the nozzle is clean and correctly installed.
- Poor Combustion or Sooting: While often related to fuel-air mixture, incorrect nozzle selection or electrode placement can contribute. Ensure the correct nozzle for your burner's firing rate is installed and electrodes are set precisely.
- Burner Lockout: If the burner repeatedly goes into lockout, it may be due to ignition failure. Confirm the electrodes are sparking correctly and are positioned according to the gauge.
For persistent issues, consult a certified oil burner technician. Do not attempt repairs beyond your technical expertise.
