10. Fault Conditions and Procedures
In the event of fault conditions the basic requirements for correct operation must be first
examined:
1. Is the signal lamp indicating the readiness for running going on (burner switch in position
”operation”)?
2. Check, that fuse is not blown or loose.
3. Check the electric supply.
4. Check that all regulating and control devices are correctly set.
5. Are the safety devices in normal operating condition?
6. Is the burner getting fuel, are the valves in fuel line open, is there oil in the tank?
When it is established, that the fault is not due to above mentioned, the individual burner
functions must be checked. Reset the burner control unit if it is in lock out position (the signal
lamp is lit). Burner starts. Observe the burner functions. Measuring instruments can be used
while finding the fault.
