This text gives procedures for servicing the burner if required.
Air Filter Cleaning
The air-filter stabilizer screen at the front of the burner may become clogged with dust and
insects thereby preventing the proper flow of air into the burner. Follow these steps to clean
the air filter:
Shut-off the fuel supply to the TEG and allow to cool.
Remove the air screen by undoing the 4 mounting screws
Clean the air-filter screen by forcing air through it or washing in water.
Replace screen and mounting screws.
If the air shutter setting was disturbed, reset the air shutter to the correct
NOTE:
range as per Air Shutter Adjustment (Section 8.1.2) before starting the TEG.
Inspection of Burner Components
Burner internals are maintenance free for most applications. If the required V
be achieved after servicing the fuel system, air filter, and checking the cooling fins and air
duct, 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.
2. Disconnect the ignition wire from the spark electrode.
3. Slide the spark electrode out of its receptacle. See Figure 2 and Figure 3.
4. Remove the air screen.
5. Disconnect the flexible fuel line from the solenoid valve.
6. Disconnect the other end of the fuel line and attached orifice from the center of the
air shutter.
NOTE:
It may be convenient to disconnect and remove the fuel system.
7. Remove the four hex-nuts holding the burner in place and slide the burner out. See
Figure 4.
