Install the Lower and Upper Vents
1. Using the following chart, decide which vents and rough opening (RO) sizes to use:
Certified Vent P/N RO Height RO Width
Upper Roof Exhaust Cap 622293 N/A N/A
Upper Roof Exhaust Vent 616319 24 in. 5 1/4 in.
Upper Exhaust & Lower Intake - Plastic 621156 13 3/4 in. 21 1/2 in.
Lower Square Corner Intake 616010 9 3/4 in. 19 3/8 in.
2. Install the lower intake vent (See Art01598, Art01599, and Art01602):
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 floor level. This allows any leaking
propane gas to escape to the outside and not to collect at floor level.
- Make sure the bottom of the opening of the lower intake vent [9] is even with or
immediately below the floor 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 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.
- If the design of the vehicle allows, install the roof exhaust vent [12] directly above the
condenser [11] of the refrigerator (See Art01598):
- Install a baffle [13] to prevent stagnant hot air in the area [14] above the refrigerator.
- Make sure there is less than 1/4 inch clearance [15] between the baffle and the
top of the refrigerator.
- Make sure the baffle is the full width of the inside of the enclosure.
- If the design of the vehicle does not allow you to install the roof exhaust vent directly above the condenser [11] of the refrigerator
(See Art01599):
- Align the roof exhaust vent [12] above the condenser [11] of the refrigerator and move it inboard as necessary.
- Install two baffles [13] to prevent stagnant hot air in the area [14] above the refrigerator.
