ventilation requireMents
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 and one lower side vent. The ventilation kits shown in this
manual have been certified for use with RM3762 and
RM3962. The table below displays the components and their
part no.

CAUTION
It is of especially importance that the airflow
around the burner housing, the boiler insulation
and the flow of combustion gases must not be
obstructed. Items placed in the vicinity of the
refrigerator compartment accordingly must be
secured away from the refrigerator tubing and
flue.
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 recom-
mended kits is provided with proper size openings. The flow of
combustion and ventilating air must not be obstructed.
The lower side vent is fitted with a panel, which provides an
adequate access opening for ready serviceability of the burner
and control manifold of the refrigerator. This should be cen-
tered on the back of the refrigerator.
ventilation heights
It is essential that all maximum or minimum dimensions are strict-
ly maintained, as the performance of the refrigerator is dependent
on adequate flow of air over the rear of the refrigerator.
