3. Nastavení a instalace

Důležité bezpečnostní upozornění: Installation of this component involves working with gas appliances and electrical connections. Incorrect installation can lead to serious injury, property damage, or death. Always ensure the boiler is isolated from the main power supply and gas supply before commencing any work. This procedure should only be carried out by a Gas Safe registered engineer or equivalent qualified professional.

1. Příprava: Ensure the boiler is switched off, isolated from the electrical supply, and the gas supply is turned off at the main isolation valve. Allow the boiler to cool down if it has been recently operating.
2. Přístup: Opatrně vyjměte kotel casing and locate the existing ignition electrode assembly. Refer to the specific boiler's service manual for exact location and access procedures.
3. Odpojení: Disconnect the electrical lead from the existing electrode. Note its orientation and connection points.
4. Odstranění: Unscrew and carefully remove the old electrode assembly. Be mindful of any existing gaskets or seals.
5. Inspekce: Inspect the area for any debris or damage. Clean as necessary.
6. Instalace nové elektrody: Place the new gasket (if supplied) onto the new electrode. Carefully insert the new electrode into its position, ensuring correct alignment. Secure it with the new mounting screws provided in the kit. Do not overtighten.
7. Spojení: Reconnect the electrical lead to the new electrode, ensuring a secure and correct connection.
8. Opětovná montáž: Replace the boiler casing.
9. Testování: Restore gas and electrical supply. Follow the boiler manufacturer's instructions for commissioning and testing the boiler to ensure proper ignition and safe operation. Check for gas leaks if any gas connections were disturbed.

4. Provoz

The ignition electrode is an integral part of the boiler's ignition sequence. When a demand for heat or hot water is initiated, the boiler's control system sends a signal to the gas valve to open and to the ignition electrode to generate a high-voltage spark. This spark ignites the gas-air mixture in the combustion chamber.

Once the flame is established, the same electrode often functions as an ionization probe. It detects the presence of the flame by sensing a small electrical current that passes through the flame itself. This ionization current signals to the boiler's control board that ignition has been successful and the flame is stable, allowing the boiler to continue its operation. If no flame is detected within a specified timeframe, the boiler will typically enter a lockout state for safety.

5. Údržba

Regular maintenance is crucial for the longevity and efficient operation of your boiler and its components, including the ignition electrode. It is recommended that your boiler undergoes an annual service by a qualified heating engineer.

• Roční kontrola: During the annual service, the engineer will inspect the ignition electrode for signs of wear, corrosion, carbon build-up, or cracking in the ceramic insulation.
• Čištění: Minor carbon deposits on the electrode can sometimes be carefully cleaned by a professional. However, if the electrode shows significant wear or damage, it should be replaced.
• Kontrola mezer: The gap between the electrode prongs is critical for proper sparking. A qualified engineer will check and adjust this gap according to manufacturer specifications if necessary.
• Nahrazení: Electrodes are wear-and-tear components and may need replacement periodically, especially if the boiler experiences frequent ignition failures or if the electrode shows visible signs of degradation.

6. Řešení problémů

If your boiler is experiencing ignition issues, the ignition electrode could be a contributing factor. Below are common symptoms and potential causes related to the electrode. Always consult a qualified heating engineer for diagnosis and repair. Do not attempt to troubleshoot or repair gas appliances yourself.

• Boiler Fails to Ignite / No Spark:
  • Možné příčiny: Faulty ignition electrode (cracked ceramic, worn prongs), incorrect electrode gap, loose electrical connection to the electrode, faulty ignition lead, or issues with the boiler's control board.
• Boiler Ignites but Locks Out (Flame Loss):
  • Možné příčiny: Faulty ionization function of the electrode, carbon build-up on the electrode preventing proper flame sensing, poor earthing, or issues with the boiler's control board not detecting the flame.
• Přerušované zapalování:
  • Možné příčiny: Electrode nearing end of life, intermittent electrical connection, or minor carbon build-up.

A qualified engineer will use specialized tools to test the electrode's resistance and ionization current, and inspect its physical condition to determine if replacement is necessary.
