N180.3
Ventilation
The installed unit must be completely
isolated from the combustion system of
the refrigerator and it must have 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.
Certified 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 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.
American Gas Association/Canadian Gas Association (AGA/CGA)
certification allows the refrigerator to have zero (0) inch minimum
clearance at the sides, rear, top, and bottom. While there are
no maximum clearances specified for certification, the following
maximum clearances are necessary for correct refrigeration:
Bottom
0 inch min.
0 inch max.
Each Side
0 inch min.
1/4 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 flow is blocked or decreased, the refrigerator may
not cool correctly.
Each NORCOLD® model is certified by AGA and CGA for correct
ventilation.

WARNING
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.
Be very careful when working on or near
the propane gas system.
Do not smoke, or use an open flame near
the propane gas system.
Do not use an open flame 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 dangerous personal injury or
death.
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 fire.
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 flare
fitting 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 flare fitting 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.
