Air Intake Vent

The ventilation and combustion air flows into the
enclosure through the air intake vent. See Figure 9.
RV front
Refrigerator Service Manual
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 9.
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.
