4. Remove the ignition cable assembly and associated green wire from the electrode
assembly. See Appendix F, Figure 17.
5. Remove the venturi, electrode assembly, spark post assembly and venturi wye based on
Figure 17, Appendix F.
6. Disassemble the burner based on Appendix F, Figure15.
7. Follow these steps to inspect the burner:
a) Check the main venturi and spark post assembly. If it looks severely corroded it should
be replaced.
b) Check the air intake is not being blocked.
c) Check the flame holder in the burner for debris, warpage, misalignment, etc. Replace if
required
8. Reinstall the burner. Tighten the three burner screws (B9 in Appendix F, Figure 15) to get
a 16mm (5/8”) gap between the two mounting plates (B7 and B8)
9. Continue to reinstall parts in the reverse order of disassembly.
Note: Both orifice fittings, on the main venturi and spark post, only need to be finger tight when
reassembling the parts.
10. Before re-starting the TEG, leak check all fuel connections.
5.3 SI SYSTEM MAINTENANCE
CAUTION: Remove the 2-position screw connector from the SI Controller board
plugged into the header labeled “IGN” to prevent accidental high
voltage shock from the igniter cable. See
Appendix G, Figure 22
5.3.1 Follow these steps to check the spark electrode:
1. Remove the spark electrode by loosening the fitting
nut at the bottom of the spark post and sliding the
electrode out, (see Appendix F, Figure 17).
2. Inspect the electrode for any cracks in the ceramic rod.
If any cracks are found the electrode must be replaced.
3. Fully insert the electrode, and then pull it back until the
ceramic rod extends the correct distance below the
spark post fitting. For Natural Gas the correct distance
is 34 mm (1.4”), For the correct distance is 26.7 mm
(1.05”). Check the TEG data plate for the fuel type,
see Figure 3.
4. Tighten the fitting nut only until it is snug. Ensure
the ceramic rod remains at the previously specified
distance.
