Fuel Filter
The fuel filter is a resin impregnated cellulose filter
which prevents solid particles from damaging the
regulator or downstream equipment. Change the
fuel filter as follows:
1)
Remove the wires from the pressure switch.
2)
Shut off the fuel supply to the TEG. Drain
the sediment bowl by opening the drain
cock.
3)
Disconnect the flexible fuel line from the
manifold block.
4)
Disconnect the vent hose from the cabinet
base .
5)
Remove the two bolts which hold the regula
-
tor to the cabinet.
6)
Turn the regulator upside down and remove
the four bolts from the bottom.
7)
Change the filter, and viton gasket, See
Figure16.
8)
Carefully replace the bottom of the regulator
making sure that the gasket is in its proper
position.
9)
Replace the four bolts and tighten.
10) Before re-installing the regulator check the
orifice, Section 3.2.2.3 and air supply, Section 3.2.3.
11) Re-install the pressure regulator. With the fuel pressure on, leak check all joints.
3.2.2.3
Fuel Orifice
Check or replace the fuel orifice as follows:
1)
Shut off the fuel supply to the TEG.
2)
Disconnect the flexible fuel line from the front of the burner.
3)
Remove the orifice fitting.
4)
Visually check the orifice hole. It should be free from any obstructions.
•
Replace if necessary.
5)
Re-assemble the fuel line, tightening all connections.
6)
Leak check all connections using a commercial leak detector.
Note: Always use the same size orifice as was removed.
For propane service use orifice #7 part 4200-00689
For natural gas use orifice #8 part 4200-00690.
WARNING: After any fuel system service, check for fuel leaks .
