To keep your Dometic refrigerator operating efficiently and
safely, periodic inspection and cleaning of several compo-
nents once or twice a year is recommended.
A. It is important to keep the area at the back of the
refrigerator clean. Check the lower vent, upper vent
and area between these openings for any obstructions
such as bird/insect nests, spider webs, etc. Clean the
coils on the back of the refrigerator. Use a soft bristled
brush to dust off the coils.

Section C. Operation Instructions
D. The LP gas pressure should be checked and the main
regulator readjusted if pressure is incorrect. The cor-
rect operating pressure is 11 inches of water column.
The correct place to take the LP gas pressure is at the
test port just ahead of the burner jet. (See FIG. 16)
E. Inspect the flue baffle. It should be reasonably clean
and free of soot. Heavy soot formation indicates im-
proper functioning of the burner. The flue and burner
both require cleaning in the following manner:
1) Unplug the refrigerator power cord from the 120 volt
2) Disconnect or shut off the 12 volt power to the
