Installation and Owner’s Guide 10Certification and Code Requirements- The refrigerator cooling system is under pressure. Do nottry to repair or to recharge a defective cooling system.- The cooling system contains sodium chromate. Thebreathing of certain chromium compounds can causecancer. The cooling system contents can cause severeskin and eye burns, and can ignite and burn with anintense flame. Do not bend, drop, weld, move, drill,puncture, or hit the cooling system.CAUTION:- The rear of the refrigerator has sharp edges and corners.To prevent cuts or abrasions when working on therefrigerator, be careful and wear cut resistant gloves.This refrigerator is certified by CSA International as meeting thelatest edition of ANSI Z21.19 / CSA 1.4 standards for installation inmobile homes or recreational vehicles.The refrigerator must be installed in accordance with this“Installation Manual” in order for the Norcold limited warrantyto be 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 Gasand Propane 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.!Art01290Ventilation Requirements!When operating in propane gas mode, the refrigerator is a directvent, or a sealed combustion system, refrigerator.The refrigerator uses a single vent / exhaust assembly, whichhas openings for both the intake of fresh combustion air andthe removal of the flue exhaust gases. There are also flexiblepipe connections between both of these vent openings and therefrigerator.This isolates the living area of the vehicle from the by-productsof combustion. The vent / exhaust assembly in this installation iscertified for this refrigerator and may not be modified.WARNING: 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 ventilationof the flue exhaust which, in gas mode, can producecarbon monoxide. The breathing of carbon monoxidefumes can cause dizziness, nausea, or in extremecases, death.- Make sure the refrigerator is completely isolated fromits heat generating components by the correct use ofbaffles and panel construction.Install the vent / exhaust assembly through the side wall of thevehicle exactly as instructed in this manual. Any other installationmethod voids both the certification and the factory warranty of therefrigerator.Each NORCOLD model is certified by CSA International forcorrect ventilation. Install only the certified vents that are listed inthis manual.Interior VentilationThe refrigerator must have a lower air intake and an upper airexhaust vent. These vents cause the natural air draft that isnecessary for good refrigeration. Cooler air goes in throughthe lower intake vent, goes around the refrigerator coils whereit removes the excess heat from the refrigerator components,and goes out through the upper exhaust vent. If this air flow isblocked or decreased, the refrigerator will not cool correctly.All propane gas supply piping and fittings must obey local, state,and national codes about type and size. These componentsmust also obey the current NFPA 501C section 2-4, and inCanada with the current CAN 1-6.10 Standard.
