Ventilation
WARNING!
The installed unit must be completely isolated from
the combustion system of the refrigerator and it must have complete and
unrestricted ventilation of the fl ue exhaust which, in gas mode, can produce
carbon monoxide. The breathing of carbon monoxide fumes can cause
dizziness, nausea, or in extreme cases, death.
Certi
fi
ed installation needs one lower intake vent and one upper
exhaust vent. Install the vents through the side wall of the vehicle
exactly as instructed in the N260.3
Installation Manual
or the
323
Installation Manual
. Any other installation method voids both the
certi
fi
cation 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
fl
oor level. This allows any leaking propane gas to escape to
the outside and not to collect at
fl
oor level.
CSA International certi
fi
cation allows the refrigerator to have zero
(0) inch minimum clearance at the sides, rear, top, and bottom.
While there are no maximum clearances speci
fi
ed for certi
fi
cation,
the following maximum clearances are necessary for correct
refrigeration:
Bottom
0 inch min.
0 inch max.
Each Side
0 inch min.
1/2 inch max.
Top
0 inch min.
1/4 inch max.
Rear
0 inch min.
1 inch max.
These clearances plus the lower and upper vents cause the natural
air draft that is necessary for good refrigeration.
Cooler air goes in through the lower intake vent, goes 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
fl
ow is blocked or decreased, the refrigerator may
not cool correctly.
Each NORCOLD® model is certi
fi
ed by CSA International for
correct ventilation.

WARNING!
Do not allow the leak detecting solution to touch the
electrical components. Many liquids are electrically conductive and can
cause a shock hazard, electrical shorts, and in some cases fi re.
Leak Test - Detergent
Using a solution of liquid detergent and water:
■
Examine the propane gas supply system for leaks: make sure
the propane gas supply line and all gas connections have no
leaks. Do not use any liquid that contains ammonia.
Leak Test - Compressed Air
If you use compressed air for the test:
■
The pressure of the compressed air at the 3/8 inch male
fl
are
fi
tting of the refrigerator must not be more than 1/2 psi (14
inches Water Column).
■
If the pressure of the compressed air is more than 1/2 psi (14
inches Water Column), remove the gas supply line from the 3/8
inch male
fl
are
fi
tting of the refrigerator before the test.
■
If the pressure of the compressed air is equal to or less than 1/2
psi (14 inches Water Column), push and turn the gas control to
the OFF ( ) position before the test.
!
Propane Gas Components
The refrigerator operates on propane gas at a pressure of 10.5
inches Water Column min. to 11.5 inches Water Column max.
WARNING!
Be very careful when working on or near the propane
gas system.
■
Do not smoke, or use an open
fl
ame near the propane gas
system.
■
Do not use an open
fl
ame to examine for leaks.
■
Do not connect the refrigerator to the propane gas tank without
a pressure regulator between them.
■
To avoid possible propane gas leaks, always use two wrenches
to tighten or loosen the propane gas supply line connections.
■
Leaking propane gas can ignite or explode and result in danger-
ous personal injury or death.

Electrical Connections
120 Volts AC Electrical Connection
The refrigerator is equipped with a three prong plug for protection
against shock hazard and must be connected into a recognized
three prong attachment receptacle. The length of cord is 24”. The
cord must be routed so as not to come in contact with the burner
cover,
fl
ue pipe or any other component that could damage the
cord insulation.
WARNING!
Do not remove (cut)grounding plug from the
refrigerator AC power cord. Removal of this prong can result in a severe
electrical shock, as well as voiding the refrigerator’s electrical certifi cation
and warranty.
■
Verify AC power cord is in a grounded three-prong receptacle.
■
Verify receptacle is within easy reach of the lower intake vent.
■
Verify power cord does not touch the burner cover, the
fl
ue
pipe, or any hot component that could damage the insulation of
the power cord.
