Ventilation Requirements; Assemble The Enclosure - Norcold N305X Installation Manual

Ventilation Requirements

!
The completed installation must:
WARNING
- 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 through the correct use of baffles
and panel construction.
Certified installation needs one lower intake vent and one upper exhaust vent. Install the upper exhaust vent either through the roof or
through the side wall of the vehicle exactly as written 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.
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 certification, the following maximum clearances are necessary for correct refrigerator
performance:
Bottom 0 inch min.
Each Side 0 inch min
Top 0 inch min.
Rear 0 inch min.
These clearances plus the lower and upper vents cause the natural air draft that is necessary for good refrigeration. Cooler air
comes in through the lower intake vent, goes up 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.

Assemble the Enclosure

1. Make sure the enclosure is 29.75 - 29.88 inches high x 20.50 - 20.63 inches wide x 21.38 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 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 fiberglass (batt-type) insulation or add a baffle to eliminate the clearance.
- The rear of the batt-type insulation must be between 14 -15 inches from the face of the enclosure.
- 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.
