Installation Manual 4Ventilation RequirementsThe 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 carbonmonoxide. 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 ofbaffles and panel construction.Certified installation needs one lower intake vent and one upper exhaust vent. Install the vents exactly as written in this manual. Anyother 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 thefloor 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. Whilethere are no maximum clearances specified for certification, the following maximum clearances are necessary for correct refrigeratorperformance: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 comesin through the lower vent, goes up around the refrigerator coils where it removes the excess heat from the refrigerator components, andgoes out through the upper 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 thismanual.WARNING!
