Installation and Owner’s Manual 12
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.
3. Install the upper exhaust vent (see Art01630):
- If you install the upper side exhaust vent:
- Make sure the distance [25] from the bottom of the
enclosure 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 [24] horizontally above the
lower intake vent [9] of the refrigerator.
- 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 construction of the vehicle does not allow the
distance [25] to be 37 inches, the distance (optional
only) can be as little as 30 3/4 inches (See Art01633) if
you:
- Install a bent aluminum or galvanized steel sheet
baffle [26] to the rear of the enclosure.
- Make sure that the bend of the baffle is flush with
the bottom edge of the upper exhaust vent opening
- Make sure the baffle is not below the top edge of
the condenser fins.
- Install a baffle [171] from the upper edge of the
lower exhaust vent that is firmly against the
absorber coils [10] of the refrigerator.
- Install a baffle [13] to prevent any stagnant hot air in
the area above the refrigerator.
- If you install the roof exhaust vent (See Art01631):
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. 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.
- 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 of
the refrigerator (See Art01632):
- Align the roof exhaust vent [12] above the lower
intake vent and move it inboard as necessary.
- Install two baffles [172] to prevent stagnant hot air
in the area [14] 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.
- If there is more than 1 inch of clearance between the
rear of the refrigerator and the enclosure, add two
baffles [171] to the rear of the enclosure (See Art01630,
Art01632 and Art01633):
- Put the baffle at the top edge of the lower intake
vent [9].
- Put the other baffle at the lower edge of the
condenser [11] of the refrigerator.
- Make sure the baffles are less than 1/4 inch
[15] from the coils [10] and condenser of the
refrigerator.
- Make sure the baffles are the full width of the
inside of the enclosure.
