Installation Manual 8
1. Install the upper roof exhaust vent.
CAUTION: Make sure that no sawdust, insulation, or other construction debris is
on the refrigerator or in the enclosure. Debris can cause a combustion hazard and
prevent the refrigerator from operating correctly.
NOTE: Tighten the screws of the upper roof exhaust cap to 10 inch-pounds max. Also
make sure that the air flow around the upper roof exhaust cap is not blocked or
decreased by other roof mounted features such as a luggage carrier, an air
conditioner, a solar panel, etc.
2. Align the upper roof exhaust vent above the lower intake exhaust vent (See Art01597):
3. Determine the type of enclosure in a vehicle using an upper roof exhaust vent (See
Art01756):
- If the distance from the face of the enclosure to the inboard edge of the roof exhaust
vent opening [169] is more than 17 1/2 inches , install the roof exhaust vent [12]
directly above the condenser [11] of the refrigerator as a vertical enclosure.
- If the distance from the face of the enclosure to the inboard edge of the roof exhaust vent opening [169] is 17 1/2 inches or less,
install the roof exhaust vent [12] inboard from the condenser [11] of the refrigerator as an offset vertical enclosure.
Install an Upper Roof Exhaust Vent
Install the Baffles for an Upper Roof Exhaust Vent
If there is more than 1/2 inch between either side of the refrigerator and the inside of the
enclosure:
- Fill the space with fiberglass (batt-type) insulation or add a baffle to eliminate the clear-
ance.
- The rear of the batt-type insulation must be between 18 3/4 -19 1/4 inches from the
face of the enclosure.
- Securely attach the batt-type insulation to the enclosure, so that it remains in this
position during refrigerator installation, if it becomes wet, and in windy conditions.
CAUTION: Make sure that all horizontal baffles are the full width of the inside of the
enclosure and are in the correct location. If the baffles are not the full width of the
enclosure or incorrectly located, poor cooling performance can result.
Vertical enclosures:
If the enclosure depth is 24 inches or more and less than 25 inches (See Art01780):
- Install a top baffle [13].
- Make sure there is less than 1/4 inch clearance between the baffle and the top of the
refrigerator.
