* These dimensions represent the minimum height 

allowable. It is recommended the Upper Vent be 

located to the maximum possible height of the 

vehicle for optimum performance in warmer climates.

: Clearance 

"M"

is between the rearmost part of

the refrigerator and the wall behind the refrigerator.

NOTE

: Clearance 

"N"

is the distance between the bot-

tom of the lower vent to the top of upper side vent. For

ventilation height, refer to Section A. Installation, Item 5.

Ventilation Heights. See FIG. 2.

Surfaces directly above and sides adjacent to the

flue outlet must be of, or covered with, fireproof

material. See FIG. 2.

NOTE:  Clearance 

"P"

over top of unit condenser fins is

1/4 inch. This is the minimum height which can be allo-

wed over the condenser fins. Whenever possible, increa-

se this height by up to 11 inches; the more ventilation

you provide, the better the performance you can expect

from the refrigerator.
