Installation Manual 4
Ventilation Requirements
The completed installation must:
- Make sure there is suffi cient 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 fl ue exhaust which, in gas mode, can produce carbon
monoxide. 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 of
baffl es and panel construction.
Certifi ed 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 certifi cation 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
fl oor level. This allows any leaking propane gas to escape to the outside and not to collect at fl oor level.
CSA International certifi cation allows the refrigerator to have zero (0) inch minimum clearance at the sides, rear, top, and bottom.
While there are no maximum clearances specifi ed for certifi cation, the following maximum clearances are necessary for 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 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.
The refrigerator also has thermostat controlled fans to move air across the cooling system. These fans turn on when the condenser fi n
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 fi n temperature at the thermostat is about 115° F or less. Even with these fans, if the air fl ow is blocked or decreased, the
refrigerator will not cool correctly.
Each NORCOLD model is certifi ed by CSA International for correct ventilation. Install only the certifi ed vents that are listed in this
manual.
In the United States and Canada:
- Local codes, or in the absence of local codes, the National Fuel Gas Code, ANSI Z223.1/NFPA 54, the Natural Gas and Propane
installation Code, CSA B149.1, ANSI A119.2 Recreational Vehicles Code, and CSA Z240 RV Series, Recreational Vehicles.
- A manufactured home (mobile home) installation must conform with the Manufactured Home Construction and Safety Standard,
Title 24 CFR, Part 3280 [formerly the Federal 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, when installed, must be electrically grounded in accordance with local codes
or, in the absence of local codes, the National Electrical code, and ANSI/NFPA 70, or the Canadian Electrical Code, CSA C22.2.
Parts 1 and 2.
All propane gas supply piping and fi ttings must obey local, state, and national codes about type and size. These components must also
obey the current NFPA 1192 section 2-4, and in Canada with the current CAN 1-6.10 Standard.
