Norcold N82X User 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 is also the
access for servicing cooling unit components.

The heat absorbed by ventilation air and combustion
gases flow out of the enclosure through the roof
exhaust vent.  See Figure 3 and Figure 4, page 23.

The roof exhaust vent is equipped with non removable
metal mesh screen that prevent 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.

The ventilation and combustion air flow into the
enclosure through the air intake vent. See Figure 3 and
Figure 4, page 23.
