B. 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 connections.
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.
C. The LP gas pressure should be checked and the
main regulator readjusted if pressure is incorrect.
The correct operating pressure is 2,7 kPa. The
correct place to take the LP gas pressure is at the
test port just ahead of the burner jet. (See FIG. 11).
D. Inspect the flue baffle. It should be reasonably
clean and free of soot. Heavy soot formation
indicates improper functioning of the burner. The
flue and burner both require cleaning in the follow-
ing manner:
1. Unplug the refrigerator power cord from the 230-
240 volt AC outlet. (See FIG. 8).
2. Disconnect or shut off the 12 volt DC power to the
refrigerator.
3. Close the gas valve by turning the knob A to
“OFF”.
4. Remove cover from the burner housing. (See fig.
1).
5. Disconnect the wire from the high voltage elec-
trode.
6. Remove the burner mounting screw and remove
the burner assembly. (See FIG. 11).
7. Lift out 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
properly clean soot and scale out of the flue tube.
Replace the flue baffle.
8. Clean burner tube with a brush. Blow out burner
with compressed air.
9. 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. Reinstall and tighten
burner jet.
! WARNING
DO NOT use a wire or pin when cleaning the burner
jet as damage can occur to the precision opening.
This can cause damage to the refrigerator or create
a fire hazard.
12. Open the gas valve by turning knob A to (GAS)
and check all fittings for leaks with soapy water.
13. Connect 230-240 volt power cord to the outlet and
reconnect the 12-volt DC power.
14. Check LP gas safety shutoff. See page 7.
4. TROUBLESHOOTING
Refrigerator Does Not Cool Properly
A. Burner jet clogged.
Clean. (See section Maintenance & Service, Item
3. Periodic Maintenance, Paragraph D. Item 1-14).
B. Check level of refrigerator.
C. Venting problem.
D. Heavy frost buildup on evaporator fins.
Defrost
E. Flue baffle not inserted properly in flue tube.
F. Improperly set thermostat.
(See Operating Instructions, part Regulating the
temperature).
G. Burner dirty.
Clean. (See section Maintenance & Service, Item
3. Periodic Maintenance, Paragraph D. Item 1-14).
H. LP gas pressure low at burner.
Set main regulator so pressure does not drop
below 2,7 kPa at pressure tap.
I. Burner not located properly under flue tube.
Relocate

(3-5 mm)
11. Be sure to reconnect the wire to high voltage
electrode. Check the electrode for proper location
and gap. (See FIG. 13).
10. Reinstall burner, being careful that the end of the
burner fits into the slot on the burner bracket.
Check to make sure slots are centred under the
flue tube and the thermocouple is positioned
properly (tip of thermocouple extends over two
slots of burner).
NOTE: The colour of the flame shall be clear blue over
the slots of the burner. (See FIG. 12).
