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 by the correct use of baffles and panel construction.
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 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.
CSA International 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 certifica- tion, the following maximum clearances are necessary for correct refrigerator performance:
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 flow is blocked or decreased, the refrigerator will not cool correctly.
Each NORCOLD model is certified by CSA International for correct ventilation. Install only the certified vents that are listed in this manual.
1.Make sure the enclosure is 20.63 - 20.76 inches high x 17.50
-17.63 inches wide x 21.25 inches 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 refrigera- tor and its contents.
3.Make sure there are no adjacent heat sources such as a furnace vent, a hot water heater vent, etc.
4.If there is more than 1/2 inch between either side of the refrigerator and the inside of the enclosure:
-Fill the space with fiberglass
-The rear of the

2. Install the lower intake vent (See Art00947 and Art00948):
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 for 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 openeing of the lower intake vent [1] is even with or immediately below the floor level [2].
-Align the lower intake vent vertically below the coils of the refrigerator.
3.Install the upper exhaust vent (See Art00947 and Art00948):
NOTE: For the best cooling performance, the distance [3] from the floor level [2] to the top of the rough opening [4] of the upper exhaust vent should be 30 1/2 inches.
