How to keep a gas burner in good working condition
To keep a gas burner in good working condition, regular care, correct operation, and timely inspection are essential.
Here’s a clear and practical guide you can follow:
1. Daily / Routine Operation
Use the correct gas type and pressure
Always operate the burner within its rated gas pressure and fuel specifications.
Ensure stable flame
The flame should be blue and steady.
Yellow or unstable flames indicate poor combustion or blockage.
Keep the burner area clean
Avoid dust, oil, or debris accumulating around the burner and air inlet.
2. Regular Cleaning
Clean burner ports and nozzles
Remove carbon deposits or dust using compressed air or a soft brush.
Check air inlets
Ensure combustion air passages are not blocked.
Inspect flame sensor / ignition electrode
Clean gently to maintain reliable ignition and flame detection.
Recommended: cleaning every 1–3 months, depending on usage and environment.
3. Inspection & Maintenance
Check gas valves and solenoid valves
Ensure smooth opening/closing and no gas leakage.
Inspect gas filter and regulator
Clean or replace filters regularly to maintain stable gas flow.
Examine seals and gaskets
Replace if cracked, hardened, or leaking.
4. Combustion Adjustment
Adjust air–gas ratio
Proper adjustment improves efficiency and reduces carbon buildup.
Monitor exhaust emissions
Excess CO or soot indicates poor combustion and needs correction.
5. Safety Checks
Leak test regularly
Use soap solution or gas detector to check all gas connections.
Verify safety devices
Flame failure device, pressure switch, and temperature limits must work correctly.
Ensure proper ventilation
Adequate airflow prevents incomplete combustion.
6. Scheduled Professional Service
Perform a full inspection annually by a qualified technician.
Replace worn parts before failure to avoid downtime.
7. Good Operating Habits
Avoid frequent start-stop cycles.
Do not exceed rated firing capacity.
Shut down properly if the burner will be idle for long periods.
