Cleaning the Exterior Surfaces of the Refrigerator
Clean the outer surface of the refrigerator with a damp sponge or cloth. Remove stubborn stains using a mild
solution of soap and warm water.
The area surrounding the refrigerator, particularly at the rear, needs to be cleaned often. Cleaning prevents dust
and other foreign materials from collecting in the burner and the flue tube. Collection of dust, spider webs, etc.,
on the refrigerator’s condenser and absorber coils (Figure 13) restricts air circulation and results in poor refrigerator
performance. Use a soft brush to clean the absorber and condenser coils.
Procedure for Cleaning Burner, Burner Orifice, and Flue (Refer to Figure 13 on Page 11)
Carbon Monoxide can be hazardous to your health and life. Gas appliances
may emit excessive Carbon Monoxide if the burner, burner orifice, and the flue
tube are not regularly cleaned. To prevent Carbon Monoxide build-up, the
burner, burner orifice, and flue tube must be cleaned at least twice a year and
after prolonged (seasonal) shut-down periods. Refer to the following cleaning
procedures, or contact a qualified installer, service agency, or your gas supplier.
1. Turn off gas at the main tank supply.
2. Turn the mode selection knob to the OFF position.
3. Allow the refrigerator to sit for 2-3 hours to insure the components at the rear of the refrigerator are cool before
cleaning.
4. Pull the refrigerator forward from its permanent location.
5. Unplug the refrigerator’s AC power cord.
Exercise care when servicing this refrigerator. The rear of this refrigerator is
extremely hot and has sharp edges. To prevent minor burns, turn the refrig-
erator off for several hours before accessing the rear of the refrigerator. Wear
cut resistant gloves to prevent cuts or abrasions while attempting to move the
refrigerator.
Cleaning the Flue
6. Remove the heat reflector cap from the flue.
7. Remove the spiral baffle assembly from the flue tube.
8. Using a stiff brush or fine emery cloth, clean spiral baffle of debris.
9. Clean the inside of the flue tube with a flue brush.
10. Re-install the spiral baffle. Insure the baffle is securely in place. The spiral baffle is required for efficient
cooling while operating in the gas mode.
Cleaning the Burner and Burner Orifice
11. Remove the screws securing the burner cover and burner box to the refrigerator.
12. Review the illustration of the burner and orifice assembly (Figure 13 on page 11).
13. Loosen the gas tube connection fitting.
14. Carefully remove the gas tube from the burner.
15. Remove the orifice and orifice gasket and clean them with alcohol and air pressure.
Do not clean the orifice
with a pin, drill, or similar object.
16. Remove the screw securing the burner to the burner bracket. Remove the burner.
17. Use air pressure to remove dust, spider webs, etc., from inside the burner. Clean the ports of the burner with a brush.
18. Clean and inspect the ignition electrode and the thermocouple. Replace if corroded.
19. Using air pressure, clean any debris from burner bracket of cooling system.
20. To reinstall, reverse the above procedures.
Make sure the orifice and orifice’s copper gasket are
assembled as illustrated in Figure 13 on page 11.
Note
: If the copper gasket shows signs of wear or damage, dispose of it and contact your dealer for a
replacement.
21. Insure the burner slots are centered under the flue tube and the ignition electrode and thermocouple are
properly located (See Figure 13).
22. Leak test all fittings using a soapy water solution. Do not leak test fittings with an open flame.
