5. Setup and Installation

Professional installation is highly recommended for gas appliances. Ensure all local codes and regulations are followed.

1. Preparation: Turn off the main gas supply to the appliance. Ensure the work area is well-ventilated.
2. Remove Old Components: Carefully disconnect and remove the existing burner assembly, gas valve, and ignition system from your stove or furnace. Note the orientation and connections for reference.
3. Install Burner Assembly: Position the new 20-row burner assembly (Figure 3) in the appliance, ensuring it is securely mounted and aligned correctly. The gas inlet should be accessible for connection.
4. Connect Flexible Gas Hose: Attach one end of the flexible gas hose to the gas inlet of the burner assembly and the other end to the gas safety valve (Figure 4). Ensure all connections are tight and use appropriate thread sealant for gas fittings.
5. Install Gas Safety Valve: Mount the gas safety valve in an accessible location, typically where the control knob can be easily operated.
6. Connect Ignition and Flameout Sensor: Connect the spark ignition electrode and the flameout protection thermocouple/sensor to the designated ports on the gas safety valve (Figure 5). Ensure the ignition electrode is positioned correctly to spark near the burner, and the thermocouple is in the flame path to detect its presence.
7. Verify Gas Type: Double-check that the installed burner and valve are compatible with your gas supply (NG or LPG). The wattage options are 3KW for LPG and 4.5KW for NG.
8. Leak Test: After all connections are made, slowly turn on the main gas supply. Apply a soap and water solution to all gas connections. Bubbles indicate a leak. If a leak is detected, turn off the gas supply immediately, tighten the connection, and re-test. Repeat until no leaks are present.

6. Operating Instructions

Once installed and leak-tested, follow these steps to operate the burner assembly:

1. Ensure Gas Supply: Confirm that the main gas supply to the appliance is ON.
2. Ignition Procedure: Locate the control knob on the gas safety valve. Push the knob IN and TURN it to the desired setting (e.g., PILOT or ON). You should hear a clicking sound from the spark igniter.
3. Observe Ignition: Keep the knob pushed in until the pilot flame (if applicable) or main burner ignites and remains lit. The flameout protection thermocouple needs a few seconds to heat up and signal that a flame is present.
4. Release Knob: Once the flame is stable, slowly release the control knob. If the flame extinguishes, repeat the ignition procedure.
5. Adjust Flame: Turn the control knob to adjust the flame intensity as needed for your appliance.
6. Shut Down: To turn off the burner, turn the control knob to the OFF position. The gas supply to the burner will be shut off.

7. Maintenance

Regular maintenance ensures optimal performance and safety.

• Cleaning: Periodically inspect the burner ports for blockages (e.g., dust, debris). Use a soft brush or compressed air to clean the ports. Ensure the burner is cool before cleaning.
• Ignition Electrode: Check the spark ignition electrode for carbon buildup or damage. Clean gently with a fine abrasive pad if necessary. Ensure the gap between the electrode and the burner is correct for reliable ignition.
• Flameout Sensor (Thermocouple): Inspect the thermocouple for corrosion or damage. A dirty or faulty thermocouple can prevent the burner from staying lit. Clean it carefully if needed.
• Gas Connections: Annually check all gas connections for leaks using a soap solution.
• Flexible Hose: Inspect the flexible gas hose for any signs of wear, cracks, or damage. Replace immediately if any damage is found.

8. Troubleshooting

9. User Tips

• Always keep the area around the burner clear of flammable materials.
• If you smell gas, immediately turn off the gas supply, open windows, and evacuate the area. Do not operate any electrical switches or phones. Contact your gas supplier or emergency services.
• For optimal performance, ensure regular cleaning of the burner and ignition components.
