– Leak test the safety shut-off valves and gas train for tightness of closure to make
sure no leakage.
– Test the pressure switch settings by checking the switch movements against
pressure settings and comparing these with the actual pressure.
– Visually check igniter cable and connectors.
– Be sure the burner bodies and air wings, the ignitor and the flame sensors are not
damaged or distorted.
13. Troubleshooting Procedures
Several reasons can cause burner failure, below a few frequent or typical common
component failures are listed that can cause burner trip.
Failure source
High gas pressure
Low gas pressure
High gas pressure at burner inlet
Gas control valve not in start
position
Process flow or combustion air flow
too low
Pilot/cooling air pressure too low
Pilot flame does not light
Main flame does not light
Pilot flame failure after ignition
Failure during operation

Possible causes:
Defective gas pressure regulator
Incorrectly adjusted gas pressure regulator
or shortage of gas supply
Limit switch or end switch not setup inside control valve
(flame length becomes excessive)
Electric or pneumatic signal for opening the control valve
fails. Control from DCS
The inlet of the air pressure switch is blocked or the port
connecting the three-way valve to the fan is blocked
Blower inlet blocked
Air pressure regulator malfunction, if used
Ignition transformer defect
Spark plug defect
Pilot gas, solenoid or the shut-off valve defect allowance
Pilot trial for ignition time is too short
Amount of start gas flow is too low
Main gas valve defective
Pilot trial for ignition time too short
Pilot flame is unstable and requires re-adjusting
UV tube defective
Shortage of combustion air
Shortage of process air
Shortage of gas supply
Customer other interlocks
