1. Before Using the Gas Burner (Pre-Start Checks)

 Gas & Air System

• Ensure gas tye (natural gas, LPG, biogas) matches burner design

• Check gas pressure is within rated range

• Open upstream manual shut-off valve

• Confirm filters are clean and not blocked

• Verify pressure regulator is stable

 Safety & Control

• Power supply is stable

• Solenoid valves open and close normally

• Ignition system (spark or pilot) is working

• Flame detector (ionization rod / UV / IR) is clean and positioned correctly

2. Correct Start-Up Procedure

1. Purge

   • Run the blower to remove residual gas from the combustion chamber

2. Ignition

   • Pilot flame ignites first (or direct spark for small burners)

   • Main gas valve opens only after flame confirmation

3. Flame Establishment

   • Flame should be:

     • Stable

     • Blue (natural gas)

     • No lifting, flashback, or flame pulsation

 If ignition fails, do not restart immediately—allow time for gas to disperse.

3. Proper Burner Adjustment (Key to Good Performance)

Air–Gas Ratio

• Adjust air damper and gas valve together

• Too much air → low efficiency, flame instability

• Too little air → yellow flame, CO formation

 Pressure Settings

• Gas pressure must match burner specifications

• Check:

  • Inlet pressure

  • Outlet pressure

  • Differential pressure (if applicable)

4. During Operation (Daily Monitoring)

• Flame remains steady and centered

• No abnormal noise, vibration, or smell

• Temperature rises smoothly

• No frequent flame failure alarms

• Control panel shows normal status

5. Routine Maintenance (Keeps Burner Working Well)

 Weekly / Monthly

• Clean burner head and air intake

• Clean flame sensor

• Check ignition electrode gap

 Quarterly / Annually

• Inspect gas valves and seals

• Calibrate pressure switches

• Check combustion efficiency (O₂ / CO / CO₂)

• Inspect refractory and combustion chamber

6. Common Problems & Quick Causes

7. Safety Rules (Very Important)

• Never bypass safety interlocks

• Always use certified components

• Stop operation immediately if gas odor is detected

• Follow local standards (EN, CE, NFPA, or ISO)

 Summary

A gas burner works well when:

• Gas pressure is correct

• Air–fuel ratio is properly adjusted

• Safety devices function correctly

• Regular maintenance is performed
