SECTION A.

LP GAS REQUIREMENTS

1A. LP GAS REQUIREMENTS

The LP gas pressure to the refrigerator should be 11 inches water column with half of all BTU’s of the RV turned on. With all other appliances turned off, the pressure to the refrigerator should not exceed 12 inches water column. To check the gas pressure when the refrigerator is operating, there is a pressure test housing located just prior to the orifice.

FLUE BAFFLE

The flue baffle is designed to concentrate the heat, from the gas flame, at a certain area of the flue tube. It should be cleaned periodically, at least once a year. To clean, remove from the flue tube and check for any damage, then clean thoroughly. See the chart on the next page for dimensions and position.

T PRESSUREEST HOUSINGTEST HOUSING

2A. LP GAS COMPONENTS

SHUT-OFF VALVE

It is the valve where the incoming LP gas supply is attached. This valve is direct coupled to the selector switch. When the selector switch is turned to the electric mode, the shut-off valve is automatically closed. When this same switch is turned to the LP gas mode, the valve opens and allows gas flow and the electric circuit to the heating elements is also automatically interrupted. To check the shut-off valve, remove and inspect for any obstructions.

BURNER

The burner is a slotted metal tube located below the flue tube on the cooling unit. It should be level and the slots, in the burner, should be directly below the flue tube. The burner should be cleaned periodically, at least once a year. To clean the burner, remove from the refrigerator and check for any foreign residue that could cause a deflection of the gas flow or the flame. Next, soak the burner in an alcohol based solvent and allow to air dry. After cleaning, reinstall in the refrigerator.

FLUE CAP (Only on applicable models)

The flue cap is located at the top of the flue tube and is attached with a screw. It must be properly attached or flame outage could occur.

FLUE TUBE

The flue tube is a component of the cooling unit. It must be cleaned periodically, at least once a year. To clean, remove flue cap and flue baffle, then cover the burner and clean by using a flue brush, Dometic Part Number 0151404001. If the flue tube becomes coated with scale or residue from combustion of LP gas, the efficiency of gas operation decreases.

NOTE: After cleaning be sure to reinstall the flue baffle and flue cap (if equipped).

ORIFICE

The orifice is a small brass fitting that has a ruby membrane that is laser beam drilled and is mounted on the gas line just prior to the burner. The orifice should be cleaned periodically, at least once a year, by using an alcohol based solvent and allowing to air dry. Never use a drill bit or jet tip cleaner to clean any orifice as these devices will damage the factory machined part and create a potentially dangerous condition.

The correct size orifice for your model refrigerator, refer to the TECHNICAL DATA section.
