LP GAS REQUIREMENTS
EST HOUSING
PRESSURE TEST HOUSING
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 refrigera-
tor 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.
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.
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.
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.
