Check Gas Pressure
The LP gas pressure should be checked and
readjusted if necessary. The correct operating
pressure is eleven inches of water column. The
correct place to take the pressure reading is at the
test port just ahead of the main orifice. (See Fig.
15).
Cleaning Flue Tube, Burner and Burner Jet
NOTE: Before working on the refrigerator make
sure that 120 volt AC and optional 12 volt DC leads
are disconnected. Shut off Gas valve.
The Burner and the Burner Jet:
The color of the flame should be clear blue over the
slots of the burner. (See fig. 14).
Once or twice a year, depending on use, clean
and adjust the burner assembly.
Proceed as follows:

Disconnect the wire from the high voltage
electrode.
Remove the burner mounting screws and
remove the burner assembly.
Clean burner tube with a brush. Blow with
compressed air.
Remove the burner jet. Soak the jet in wood
alcohol and blow it out with compressed air.

Remove the flue cap from the top of flue
tube and lift out the wire and spiral baffle.
Clean the flue from the top, using a flue
brush. Replace spiral baffle and flue cap.
Remove all loose scale, soot, etc., from
area below the flue pipe. (See Fig. 15).
Reassemble.
Be careful that the end of the burner fits
into the slot on the bracket. The slots of
the burner must be centrally located
under the flue tube.
The gas fittings on the refrigerator need
to be checked for leaks. Turn on the gas
supply at the shut-off valve. Apply a non-
corrosive bubble solution to the fitting
and observe for leaks. The safety valve
will not allow gas pressure to any
connections between it and the burner
jet. These fittings must be checked
before burner is lighted.
CAUTION
The safety shut-off must be manually depressed to
allow gas pressure to flow to the burner jet. Be sure
to apply the leak check solution before depressing
the safety shut-off. DO NOT allow any open flame,
sparks, smoking, etc., in the area of the test. DO
NOT depress safety shut-off for over 30 seconds.
