MAINTENANCE & SERVICE
REFRIGERATOR REMOVAL
Before working on the refrigerator, make sure the AC voltage
leads are disconnected. Shut off the gas supply. Disconnect the
gas supply line at the rear of the refrigerator. Always use a back
up wrench when loosening and tightening this connection. Cap
the gas supply line and remove the refrigerator. Replacement
is the reverse of removal. Check all connections for gas leaks.
Refer to section INSTALLATION.
PERIODIC MAINTENANCE
To keep your refrigerator operating efficiently and safely, peri-
odic inspection and cleaning of several components is recom-
mended once or twice a year.
It is important to keep the area at the back of the refrigerator
clean. Clean the coils on the back of the refrigerator. Use a soft
bristled brush to dust off the coils. It is important to keep the
refrigerator area free from combustible material, gasoline and
other flammable vapors or liquids.
The following maintenance is required once or twice a year, but
should only be done by a qualified serviceman who is familiar
with LP gas systems and refrigerators.
Check all connections in the LP gas system
Check all connections in the LP gas system (at the back of the
refrigerator) for gas leaks. The LP gas supply must be turned
on. Apply a non-corrosive bubble solution to all LP gas connec-
tions. The appearance of bubbles indicates a leak and should
be repaired immediately by a qualified serviceman who is
familiar with gas system and refrigerators.
WARNING! DO NOT use a flame to check for
gas leaks.
Check burner ame
Check burner flame for proper
appearance. The flame should be
light blue with no yellow at the tip.
Check the LP gas pressure
The LP gas pressure should be checked and the main regulator
readjusted if pressure is incorrect. The correct operating pres-
sure is 11 inches of water column. The correct place to take the
LP gas pressure is at the test port just ahead of the burner jet.
Inspect the ue bafe
It should be reasonably clean and free of soot. Heavy soot for-
mation indicates improper functioning of the burner. The flue
and burner both require cleaning in the following manner:
Unplug the refrigerator power cord from the 120 volt
AC outlet.
Turn the knob (A) to “OFF” position.
Remove cover from the burner housing.
Disconnect the wire from the high voltage electrode.
Remove the burner mounting screw and remove the
burner assembly.
Remove the wire and flue baffle from the top of flue
tube. Clean the flue from the top using a flue brush.
Blowing compressed air into the flue will not prop-
erly clean soot and scale out of the flue tube. Replace
the flue baffle.
Clean burner tube with a brush. Blow out burner
with compressed air.
Before removing burner jet, clean burner area of
soot and scale that fell out of flue tube. Remove the
burner jet. Soak the jet in wood alcohol and blow
it out with compressed air. Re-install and tighten
burner jet.
CAUTION
DO NOT use a wire or pin when
cleaning the burner jet as damage
can occur to the precision open-
ing. This can cause damage to the
refrigerator or create a fire hazard.
Reinstall burner, being careful that the end of the
burner fits into the slot on the burner bracket. Check
to make sure slots are centered under the flue tube
and the thermocouple is positioned properly (tip of
thermocouple extends over two slots of burner).
Be sure to reconnect the wire to high voltage elec-
trode. Check the electrode for proper location and
gap.
The gas fittings on the refrigerator need to be
checked for leaks. Turn the knob (A) to position
“GAS”. 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.

The user should be aware of service that must be done on a regular schedule to keep the refrigerator operating properly.
A qualified technician who is familiar with LP gas systems and refrigerators should only perform the service.
