Procedure For Cleaning Burner, Burner Orifice, And Flue - Norcold 1082 Service Manual

Procedure for Cleaning Burner, Burner Orifice, and Flue-Figure 16
WARNING: 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.
CAUTION: Exercise care when servicing this refrigerator. The rear of this refrigerator is extremely
hot and has sharp edges. To prevent minor burns, turn the refrigerator 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

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 16 on page 17.
CAUTION: If the copper gasket shows signs of wear or damage, replace with new.
21. Insure the burner slots are centered under the flue tube and the ignition electrode and thermocouple are
properly located (See Figure 14).
