Owner’s Manual 11
Ventilation Requirements
WARNING:
The completed installation must:
- Make sure there is sufficient intake of fresh air for
combustion.
- Make sure the living space is completely isolated from
the combustion system of the refrigerator.
- Make sure there is complete and unrestricted ventilation
of the flue exhaust which, in gas mode, can produce
carbon monoxide. The breathing of carbon monoxide
fumes can cause dizziness, nausea, or in extreme
cases, death.
- Make sure the refrigerator is completely isolated from its
heat generating components through the correct use of
baffles and panel construction.
Certified installation needs one lower intake vent and one upper
exhaust vent. Install the upper exhaust vent either through the
roof or through the side wall of the vehicle exactly as written
in this manual. Any other installation method voids both the
certification and the factory warranty of the refrigerator.
The bottom of the opening for the lower intake vent, which is also
the service access door, must be 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.
While there are no maximum clearances specified for
certification, the following maximum clearances are necessary for
correct refrigeration:
Bottom
0 mm min.
0 mm max.
Each Side
0 mm min
3 mm max.
Top
0 mm min.
6 mm max.
Rear
0 mm min.
25 mm max.
These clearances plus the lower and upper vents cause the
natural air draft that is necessary for good refrigeration. Cooler
air comes in through the lower intake vent, goes up around the
refrigerator coils where it removes the excess heat from the
refrigerator components, and goes out through the upper exhaust
vent. If this air flow is blocked or decreased, the refrigerator will
not cool correctly.
Assemble the Enclosure
1. Make sure the enclosure is:
N304 models
756 mm high x 521 mm wide x 543 mm deep.
N404 models
929 mm high x 602 mm wide x 620 mm deep.
N504 models
1083 mm high x 602 mm wide x 620 mm deep.
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
refrigerator and its contents.
3. Make sure there are no adjacent heat sources such as a
furnace vent, a hot water heater vent, etc.
Install the Lower and Upper Vents
1. Using the following chart, decide which vents and rough
opening (RO) sizes to use.

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 refrigerator.
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.
- Align the lower intake vent [9] vertically below the coils [10]
and the condenser [11] of the refrigerator.
