Installation Manual 3Certification and Code Requirements Ventilation RequirementsWARNING: The completed installation must:- Make sure there is sufficient intake of fresh air forcombustion.- Make sure the living space is completely isolated fromthe combustion system of the refrigerator.- Make sure there is complete and unrestricted ventila-tion of the flue exhaust which, in gas mode, canproduce carbon monoxide. The breathing of carbonmonoxide fumes can cause dizziness, nausea, or inextreme cases, death.- Make sure the refrigerator is completely isolated fromits heat generating components through the correctuse of baffles and panel construction.Certified installation needs one lower intake vent and one upperexhaust vent. Install the vents exactly as written in this manual.Any other installation method voids both the certification and thefactory warranty of the refrigerator.The bottom of the opening for the lower intake vent, which isalso the service access door, must be even with or immediatelybelow the floor level. This allows any leaking propane gas toescape to the outside and not to collect at floor level.CSA International certification allows the refrigerator to havezero (0) inch minimum clearance at the sides, rear, top, andbottom. While there are no maximum clearances specified forcertification, the following maximum clearances are necessaryfor 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 thenatural air draft that is necessary for good refrigeration. Coolerair comes in through the lower vent, goes up around therefrigerator coils where it removes the excess heat from therefrigerator components, and goes out through the upper vent.If this air flow is blocked or decreased, the refrigerator will notcool correctly.Each NORCOLD model is certified by CSA International forcorrect ventilation. Install only the certified vents that are listedin this manual.This refrigerator is certified by CSA International as meeting thelatest edition of ANSI Z21.19 / CAN 1.4 standards for installationin mobile homes or recreational vehicles.The refrigerator must be installed in accordance with this“Installation Manual” in order for the Norcold limited warranty tobe in effect. In addition, the installation must conform to thefollowing, as applicable:In the United States and Canada:- Local codes, or in the absence of local codes, the NationalFuel Gas Code, ANSI Z223.1/NFPA 54, the Natural Gas andPropane installation Code, CSA B149.1, ANSI A119.2Recreational Vehicles Code, and CSA Z240 RV Series,Recreational Vehicles.- A manufactured home (mobile home) installation mustconform with the Manufactured Home Construction andSafety Standard, Title 24 CFR, Part 3280 [formerly theFederal Standard for Mobile Home Construction and Safety,Title 24 (part 280), and the current CSA Z240.4, Gas-equipped Recreational Vehicles and Mobile Housing.- If an external power source is utilized, the appliance, wheninstalled, must be electrically grounded in accordance withlocal codes or, in the absence of local codes, the NationalElectrical code, and ANSI/NFPA 70, or the CanadianElectrical Code, CSA C22.2. Parts 1 and 2.All propane gas supply piping and fittings must obey local,state, and national codes about type and size. Thesecomponents must also obey the current NFPA 501C section 2-4, and in Canada with the current CAN 1-6.10 Standard.
