Norcold 323 - Assemble the Enclosure

Installation Manual 4
Certi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 this manual. Any other installation method voids both the certi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
oor level. This allows any leaking propane gas to escape to the outside and not to collect at oor level.
CSA International certi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ed for certication, 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 ow is blocked or decreased, the refrigerator may not cool correctly.
Each NORCOLD model is certied by CSA International for correct ventilation. Install only the certied vents that are listed in this
manual.
Assemble the Enclosure
1. Make sure the enclosure is the correct size:
- for 323 models it must be 20.63 - 20.76 inches high x 17.50 - 17.63 inches wide x 21.25 inches deep.
- for N260.3 models it must be 20.81 - 20.87 inches high x 19.38 - 19.44 inches wide x 24.38 inches deep.
2. Make sure the oor is solid and level.
- The oor must be metal or a wood panel and extend the full width and depth of the enclosure.
- The oor must be able to support the weight of the refrigerator 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 berglass (batt-type) insulation or add a bafe to eliminate the clearance.
- The rear of the batt-type insulation must be between 14-15 inches from the face of the enclosure for 323 models and between
18 -19 inches from the face of the enclosure for N260.3 models.
- Securely attach the batt-type insulation to the enclosure, so that it remains in this position during refrigerator installation, if it
becomes wet, and in windy conditions.
