Installation Manual 4
- Align the lower intake vent [1] vertically below the coils [2]
and the condenser [3] of the refrigerator.
3. Install the upper exhaust vent:
- If you install the roof exhaust vent (see Art01638):
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 [9] directly above the condenser [3] of the
refrigerator.
- Install a baffle [10] to prevent stagnant hot air in the
area [7] above the refrigerator.
- Make sure there is less than 1/4 inch clear-
ance [11] 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 [9] above the lower
intake vent and move it inboard as necessary (See
Art01639).
- Install two baffles [12] and [13] to prevent stagnant
hot air in the area [7] above the refrigerator.
- Make sure both baffles are the full width of the
inside of the enclosure.
- Make sure that both baffles are no more than
45° from vertical [19].
- Put one baffle between the top rear edge of the
refrigerator and the inside edge of the upper
exhaust vent opening.
- Make sure there is less than 1/4 inch
clearance [11] between the baffle and the
top of the refrigerator.
- Put the other baffle between the outside edge
of the upper exhaust vent opening and the
side wall of the vehicle.
- If you install the upper side exhaust vent (See Art01637):
Assemble the Enclosure
1. Make sure the enclosure is:
- 36.56 - 36.69 inches high x 23.69 - 23.82 inches wide x 24
inches deep for N400 models.
- 42.63 - 42.69 inches high x 23.69 - 23.82 inches wide x 24
inches deep for N510 models.
2. Make sure the floor is solid and level.
- The floor must be metal or a wood panel and extend the full
width and depth of the enclosure.
- The floor must be able to support the weight of the refrigera-
tor and its contents.
3. Make sure there are no adjacent heat sources such as a
furnace vent, a hot water heater vent, etc.

2. Install the lower intake vent (See Art01608):
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 lower intake vent is
even with or immediately below the floor level.
