The installation must obey these standards and this  
“Installation Manual” for the NORCOLD limited warranty to  
be in effect. Installation must conform with local codes. In  
the absence of local codes, the installation must obey  
these standards:  
Certified installation needs one lower intake vent and one upper  
exhaust vent. Install the vents 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.  
In the United States:  
- National Fuel Gas Code, ANSI Z223.1.  
- Manufactured Home Construction and Safety Standard, Title  
24 CFR, Part 32-80.  
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:  
- Standard for Recreational Vehicles, RVIA A119.2 latest  
edition.  
- For installations which need an electric outlet that is  
energized by an external power source, the refrigerator  
must be electrically grounded as written in local or state  
codes, the National Electrical code, and ANSI/NFPA 70.

- Current CGA B149.1 and CGA B149.2 Installation code for  
Propane Appliances and Equipment.  
These clearances plus the lower and upper vents allow the  
natural air draft that is necessary for good refrigeration. Cooler  
air comes in through the lower vent, goes up around the  
refrigerator coils where it removes the excess heat from the  
refrigerator components, and goes out through the upper vent.  
- Current CSA Z240.4.2 Installation Requirement for Propane  
Appliances and Equipment in Recreational Vehicles.  
- Current CSA Z240.6.2/C22.2 No. 148 Electrical  
Requirement for Recreational Vehicles.  
The refrigerator also has two thermostat controlled fans to  
move air across the cooling system. These fans turn on when  
the condenser fin temperature at the thermostat is about 130° F  
or higher and only when the refrigerator controls are on. These  
fans turn off when the condenser fin temperature at the thermo-  
stat is about 115° F or less. Even with these fans, if the air flow  
is blocked or decreased, the refrigerator will not cool correctly.  
-
When installed, the refrigerator must be electrically  
grounded in accord with local or state codes, the Canadian  
Electrical Code C22.2. Parts 1 and 2.  
All propane gas supply piping and fittings must obey local,  
state, and national codes about type and size. These  
components must also obey the current NFPA 501C section 2-  
4, and in Canada with the current CAN 1-6.10 Standard.  
Each NORCOLD model is certified by CSA International for  
correct ventilation. Install only the certified vents that are listed  
in this manual.
