The space between the air intake vent and the rear
of the refrigerator must be kept clear at all times. Any
obstruction in this area may cause serious ventilation
problems. The air intake vent opening also provides
access for servicing cooling unit components.
Roof Exhaust Vent
The heat absorbed by ventilation air and combustion
gases flow out of the enclosure through the roof exhaust
vent. See Figure 10 below and Figure 11, page 18.
The roof exhaust vent is equipped with a non-
removable metal mesh screen that prevents leaves,
debris, birds or rodents from getting into the enclosure.
The roof cap is fastened to the exhaust vent with four
screws. The cap is always installed with the slope
towards the front of the RV.
