Assemble The Enclosure; Install The Lower And Upper Vents - Norcold N300 Installation And Owner's Manual

Assemble the Enclosure

- Make sure the enclosure is 29 3/4 inches high x 20 1/2
inches wide x 21 3/8 inches deep.
- 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.
- Make sure there are no adjacent heat sources such as a
furnace vent, etc.

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
Upper Roof 622293
Exhaust Vent
Upper Side 617485
Exhaust Vent
Lower Side 617484
Intake Vent
2. Install the lower intake vent (See Art 00968):
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 [1] vertically below the coils [2]
and the condenser [3] of the refrigerator.
3. Install the upper exhaust vent (see Art00969):
- If you install the upper side exhaust vent:
- Make sure the distance [4] from the floor level to the
top of the rough opening for the upper exhaust vent is
at least 37 inches or poor cooling performance can
occur.
- Align the upper exhaust vent [5] vertically above the
coils [2] and the condenser [3] of the refrigerator.
- Install a baffle [6] to prevent stagnant hot air in the area
[7] above the refrigerator (see Art01249).
- Make sure there is less than 1/4 inch clearance [8]
between the baffle and the top of the refrigerator.
RO Height RO Width
24 in. 5 1/4 in.
7 1/4 in. 18 in.
9 3/4 in. 19 3/8 in.
- Make sure the baffle is the full width of the inside of
the enclosure.
- If the construction of the vehicle does not allow the
distance [4] to be 37 inches, the distance (optional
only) can be as little as 30 3/4 inches (See Art01291) if
you:
- Install a baffle [15] from the lower edge of the
upper exhaust vent [5] to the top edge of the
condenser fins.
- Make sure the baffle is not below the top edge of
the condenser fins.
- Install a baffle [14] from the upper edge of the
lower exhaust vent that is firmly against the
absorber coils [2] of the refrigerator.
- Install a baffle [10] to prevent any stagnant hot air in
the area above the refrigerator.
- If you install the roof exhaust vent (See Art01250):
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 roof cap to 10 inch-pounds
max.
- 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:
- Center the roof exhaust vent [9] above the con-
denser [3] of the refrigerator, but move it inboard
as necessary (see Art01251).
- 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.
- Put one baffle between the top rear edge of the
refrigerator and the inside edge of the upper
exhaust vent opening.
- Put the other baffle between the outside edge
of the upper exhaust vent opening and the
side wall of the vehicle.
