Ventilation Requirements - Dometic DMR702 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 or one upper side vent and one lower
side vent. The ventilation kits shown in this manual have been
certified for use with DMR/DMC 7-series. The table below
displays the components and their part no.

* Replace "XXX" with the color code numbers. For color codes,
contact your supplier. For further information, contact your dealer or
distributor.
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.
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.

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.

NOTE! Ventilation height should be measured from
the seam between the frame and door of the lower side
