Upper Roof Exhaust Cap 622293 N/A N/A 10½ in. x 33 in.
Upper Roof Exhaust Vent 616319 24 in. 5 1/4 in. 7 7/16 in. x 26 7/23 in.

Universal Upper and Lower Vent 620505xx 6 3/16 in. 17 13/16 in. 8 5/32 in. X 19 5/8 in.
Install the vents exactly as described. Any other method will invalidate the warranty for the refrigerator.
2. Install the lower intake vent (See Art02337, Art02338, and Art02339):
The lower intake vent is also the service access opening for the components on
the rear of the refrigerator.
Make sure the bottom of the opening of the lower intake vent is even
with or immediately below the fl oor level. This allows any leaking
propane gas to escape to the outside and not to collect at fl oor level.
- Make sure the bottom of the opening of the lower intake vent [9] is even with or immediately
below the fl oor level.
- Align the lower intake vent vertically below the coils [10] and the condenser [11] of the
refrigerator.
3. Install the upper exhaust vent:
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.
Tighten the screws of the upper roof exhaust cap to 10 inch-
pounds max. Also make sure that the air fl ow 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.
- If the design of the vehicle allows, install the roof exhaust vent [12] directly
above the condenser [11] of the refrigerator (See Art02337):
- Install a baffl e [13] to prevent stagnant hot air in the area [14] above the
refrigerator.
