VENTILATION REQUIREMENTS
WARNING: Carbon Monoxide can cause nausea, fainting, or death. Inadequate ven- tilation or partial blockage of the refrigera- tor’s flue can result in increased carbon monoxide emissions when operating in the gas mode. To prevent the emission of lev- els of carbon monoxide, installation must assure complete isolation of the living space of the R.V. from the refrigerator’s combustion system. Follow Norcold’s Ven- tilation and Installation recommendations explicity.
Venting is required in an R.V. refrigerator installa- tion to remove the products of combustion, to isolate the living space of the vehicle from the combustion system of the refrigerator, to remove the excess heat from the generator area of the refrigerator’s cooling system, and to remove the heat that is extracted from the refrigerator cabinet.
Certified installation requires that one intake (lower) and one exhaust (upper) be used. For the models 6052, 6053, 652, and 653, the installer has the op- tion of exhausting through the roof or through an up- per side wall vent. Whether roof or side wall exhaust venting, the specified vent kit must be installed as directed by this manual. To insure adequate refrig- erator performance, a continuous air flow is required across the refrigerator’s cooling system.
The air passage from the intake vent to the refrigera- tor coils and from the refrigerator coils through the exhaust vent must be unobstructed.
TABLE 1
DIMENSIONS (INCHES) for Vent Kits 2, 3, and 4
The vents for these refrigerators are certified by A.G.A. and CGA and must be installed as directed by this manual without modification. Any deviation or substitution:
*Can result in carbon monoxide levels in the living space of the vehicle.
*Will void the agencies’ certification.
*Will void the refrigerator warranty.
*Will effect refrigerator performance.
The intake vent (lower) also serves as a access (service entrance) door. The bottom of the intake vent opening must be flush with the surface on which the refrigerator is mounted. This configuration allows any leaking propane to ventilate to the outside.
A.G.A. And CGA certification permits installing the refrigerator with zero (0) inches minimum clearance between the refrigerator and any adjacent walls. This certification does not specify any maximum clear- ance. However, to insure adequate air flow across the cooling system, the clearance must be mini- mized. The combination of the two vents and the minimum clearances provide the necessary air flow through the creation of a natural draft, or "chimney effect" across the cooling system.
