3. Align the sediment bowl with the regulator body, replace the four screws and tighten.
4. With the fuel pressure on, leak check all regulator joints and fuel connections using a
commercial leak detector.
5.1.2 Fuel Orifice Inspection
Follow these steps to inspect the fuel orifice, see Appendix F, Figures 16 & 17:
1. Shut off the fuel supply and allow TEG to cool; approximately 1 hour.
2. Disconnect the fuel line from the solenoid valve.
3. Disconnect the other end of the fuel line from the orifices on the main and pilot line.
4. Remove the orifice fitting from the spark post and main venturi.
5. Visually check each orifice hole. It should be free from any obstructions. Replace it if
necessary. Use a magnifying glass to aid with visual inspection.
6. Connect the orifice fittings back on the spark post and venturi. Both orifice fittings (on the
main venturi and spark post) only need to be finger tight when reassembling the parts.
CAUTION: Always use the same size orifice as was removed.
(See Appendix F - Parts list)
7. Connect the fuel line to solenoid valve and orifice, then tighten the fuel line fittings.
8. Leak check all connections using a commercial leak detector.
5.2 BURNER MAINTENANCE
Burner internals are maintenance free for most applications. If the required power still
cannot be achieved after servicing the fuel system, air filter and checking the cooling fins
then it may be necessary to check and service the burner internals. The procedures below
give the steps for inspecting the burner components.
Follow these steps to remove the burner:
1. Shut off the fuel supply to the TEG and allow to cool.
WARNING: The burner reaches extreme temperatures. The TEG must cool
for at least 3 hours or more, otherwise personal injury will result during
handling. Always be cautious when beginning maintenance since parts
may not yet have cooled sufficiently to handle.
2. Disconnect the supply fuel line and fuel inlet valve.
3. Disconnect the solenoid wire terminal connections and the pressure switch wire
connections.
