Keep the Burner Clean

• Remove dust, carbon buildup, and oil residue regularly.

• Clean the burner head, nozzles, and air openings so the flame can burn evenly.

 Check Air–Fuel Ratio

• Make sure air and gas are balanced.

• Too much air → weak flame.

• Too little air → yellow flame, soot, high fuel consumption.

Inspect Gas Supply System

• Check gas filter, pressure regulator, solenoid valve, and pipe connections.

• Ensure there is no leakage and pressure is stable.

Maintain Ignition System

• Inspect spark plug/electrode and ignition cable.

• Keep electrode gap correct and clean for reliable ignition.

Observe Flame Condition

A healthy flame should be:

• Blue or blue-white

• Stable, not shaking

• Not producing black smoke

If the flame is yellow or noisy → adjust air or check burner head.

Check Safety Devices

• Flame detector (UV/IR sensor)

• Temperature limits

• Pressure switches
  Make sure they respond correctly.

Follow Regular Maintenance Schedule

Daily: visual check, flame observation
Monthly: clean filters, check gas pressure, clean burner head
Yearly: full service by a professional

Keep the Area Around the Burner Clean

• No dust, oil, water, or obstacles

• Good ventilation helps stable combustion
