GENERAL INFORMATION
Ventilation is one of the requirements for proper cooling
unit operation. The installation should be made in such a man-
ner as to separate the combustion system from the living space
of the mobile home or recreational vehicle. Openings for air
supply or for venting of combustion products should have a
minimum dimension of not less than 1/4 inch.
Proper installation requires one lower fresh air intake and one
upper exhaust vent. Certified installations require one roof
vent vent and one vent and one lower side vent. The ventilation kits shown in this
manual have been certified for use with RM 3762 and
RM 3962. The table below displays the components and their

The ventilation kits must be installed and used without modi-
fication! An opening toward the outside at floor level in the
refrigerator compartment has to be provided for ventilation of
heavier-than-air fuel gases. The lower vent of the recommended
kits is provided with proper size openings. The flow of combus-
tion and ventilating air must not be obstructed.
The lower side vent is fitted with a panel, which provides an ad-
equate access opening for ready serviceability of the burner and
control manifold of the refrigerator. This should be centered on
the back of the refrigerator.
