Ventilation Requirements - Dometic RM2620 Installation & Operating Instructions Manual

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 RM2620 and
RM2820. The following table displays the components and
their part no.

The ventilation kits must be installed and used without
modification! An opening toward the outside at floor level in
the refrigerator compartment has 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.
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 ob-
structed. Items placed in the vicinity of the refrig-
erator compartment accordingly must be secured
away from the refrigerator tubing and flue.
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
strictly maintained, as the performance of the refrigerator is de-
pendent on adequate flow of air over the rear of the refrigerator.
