Ekgas, cleaning a gas burner regularly helps maintain stable flames, high efficiency, and safe operation. Here’s a clear, step-by-step guide you can use for domestic or industrial gas burners (the principles are the same, only the scale differs).

1. Safety First

Before any cleaning work:

• Shut off the gas supply

• Turn off electrical power (ignition system, blower, controller)

• Allow the burner to cool completely

• Wear gloves and safety glasses

2. External Surface Cleaning

• Wipe the burner body with a dry cloth or soft brush

• For oil or grease:

  • Use a mild detergent or industrial degreaser

  • Avoid spraying liquid directly into gas ports

Do not use corrosive chemicals or high-pressure water.

3. Clean Burner Ports / Nozzles

Clogged ports cause yellow flames and unstable combustion.

Steps:

• Use a soft wire brush, toothpick, or compressed air

• Clean each port gently to avoid enlarging the holes

• Blow out dust and debris with dry compressed air

Never drill or modify burner holes.

4. Inspect and Clean the Gas Injector

• Remove the injector/nozzle if accessible

• Clean with:

  • Compressed air

  • Soft brush

• Replace if worn or damaged

A dirty injector often causes poor flame shape or low heat output.

5. Clean Air Intake and Mixing Area

• Remove dust, lint, or grease from:

  • Air shutters

  • Venturi/mixing tube

• Ensure air openings are not blocked

Good air–gas mixing is critical for blue, stable flames.

6. Ignition & Flame Sensor Maintenance

• Clean spark electrode and flame rod using:

  • Fine sandpaper or a clean cloth

• Check electrode gap and alignment

• Replace cracked or heavily corroded parts

Dirty sensors can cause ignition failure or flame loss alarms.

7. Reassemble and Test

• Reinstall all components securely

• Open gas supply slowly

• Perform a leak check (soap solution)

• Start the burner and observe:

  • Flame color (blue preferred)

  • Flame stability

  • Noise or vibration

8. Recommended Cleaning Frequency

Warning Signs That Cleaning Is Needed

• Yellow or lifting flames

• Uneven flame distribution

• Soot formation

• Higher gas consumption

• Difficult ignition
