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. Certifi ed installations require one roof vent

and one lower side vent. The ventilation kits shown in this  

manual have been certifi ed for use with the different models as 

displayed in the “Certifi ed Vent System Kits” table.

The ventilation kits must be installed and used without 

modifi cation! An opening toward the outside at fl oor level 

in the refrigerator compartment has be provided for ventila-

tion of heavier-than-air fuel gases. The lower vent of the 

recommended kits is provided with proper size openings. 

The fl ow of combustion and ventilating air must not be 

obstructed. 
The lower side vent is fi tted with a panel, which provides 

an adequate access opening for ready serviceability of the 

burner and control manifold of the refrigerator. This should 

be centered on the back of the refrigerator.
