4.5 Burner Head and Electrode Servicing
Step 1:
Check the pepper pot burner head for
contamination. If necessary this can be
removed. See below. This can be cleaned
together with the inside of the burner tube.
Step 2:
The pepper pot burner head can be
replaced ensuring the 5 holes on the outer ring
are aligned alongside the probes.
Step 3:
The condition of the igniter assembly
can be checked for deterioration. However, we
advise replacement at each service to ensure
continued reliability.
Step 4:
Detach the electrode assembly from
the burner head by removing the two screws
and separating the igniter lead connectors.
Step 5:
Refit the electrode assembly and ensure
the connections are secure to prevent incorrect
sparking of the spark electrode.
Step 6:
Check the positions and spark gap as
shown below.
Step 7:
The burner assembly is ready to refit
after servicing the combustion fan and the
radiant tube assembly.
