2. Install the lower intake vent:

NOTE: The lower intake vent is also the service access opening for the components on the rear of the refrig- erator.

WARNING: 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

[1]is even with or immediately below the floor level (See Art01597).

-Make sure that the opening for the lower intake vent is between 1/2 inch and 1 inch from the burner side of the refrigerator enclosure.

3.Install the upper 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.

-If the design of the vehicle allows, install the roof exhaust vent [2] directly above the lower intake vent [1] (See Art01597 and Art01596).

-Install a baffle [4] to prevent stagnant hot air in the area

[5]above the refrigerator.

-Make sure there is less than 1/4 inch clearance [6] 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 of the refrigerator:

-Align the roof exhaust vent [2] above the lower intake vent and move it inboard as necessary (See Art01597 and Art01595).

-Install two baffles [7] to prevent stagnant hot air in the area [5] above the refrigerator.

-Make sure the baffles are the full width of the inside of the enclosure.

-Make sure that the baffles are no more than 45° from vertical [8].

-Put one baffle between the top rear edge of the refrigerator and the inside edge of the roof exhaust vent opening.

-Put the other baffle between the outside edge of the roof exhaust vent opening and the side wall of the vehicle.

-If the depth of the enclosure is 24 inches or more and is less than 25 inches, no baffles are necessary at the rear of the enclosure.

-If the depth of the enclosure is 25 inches or more and is less than 26 inches, add two baffles [9] to the rear of the enclosure (See Art01595 and Art01596).

-Put one baffle 18 inches to 18 1/2 inches above the bottom of the enclosure [25] (4 1/4 inches to 4 3/4 inches above the top of the lower intake vent opening REF) [26] .

-Put the other baffle at the lowest edge of the condenser

[3]of the refrigerator.

-Make sure that the baffles are 1 inch or less [27] from the coils [2] and condenser of the refrigerator.

-Make sure that the baffles are the full width of the inside of the enclosure.

-If the depth of the enclosure is more than 26 inches, install a wood or an aluminum or galvanized sheet solid box baffle [28] in the rear of the enclosure (See Art01644 and Art01645).
