damage.
Safety Instructions
!
WARNING
- This refrigerator is not approved for use as a free standing refrigerator. It is equipped for the use of propane gas only
and can not be changed to use any other fuels (natural gas, butane, etc.).
- Incorrect installation, adjustment, alteration, or maintenance of this refrigerator can cause personal injury, property
damage, or both.
- Obey the instructions in this manual to install the intake and exhaust vents.
- Do not install the refrigerator directly on carpet. Put the refrigerator on a metal or wood panel that extends the full
width and depth of the refrigerator.
- Do not allow anything to touch the refrigerator cooling system.
- Propane gas can ignite and cause an explosion that can result in property damage, personal injury, or death. Do not
smoke or create sparks. Do not use an open ame to examine the propane gas supply line for leaks. Always use two
wrenches to tighten or loosen the propane gas supply line connections.
Installation Manual 2
- Make sure the electrical installation obeys all applicable codes. See “Certication and Code Requirements” section.
- Do not bypass or change the refrigerator’s electrical components or features.
- Do not spray liquids near electrical outlets, connections, or the refrigerator components. Many liquids are electrically
conductive and can cause a shock hazard, electrical shorts, and in some cases re.
- The refrigerator cooling system is under pressure. Do not try to repair or to recharge a defective cooling system.
- The cooling system contains sodium chromate. The breathing of certain chromium compounds can cause cancer. The
cooling system contents can cause severe skin and eye burns, and can ignite and burn with an intense ame. 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 the
refrigerator, use caution and wear cut resistant gloves.
Certication and Code Requirements
This refrigerator is certied by CSA International as meeting the
latest edition of ANSI Z21.19 / CSA 1.4 standards for installation
in mobile homes or recreational vehicles.
The refrigerator must be installed in accordance with this
“Installation Manual” in order for the Norcold limited warranty
to be in effect. In addition, the installation must conform to the
following, as applicable:
In the United States and Canada:
Art01290
- 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 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.
Ventilation Requirements
!
WARNING
- Make sure there is sufcient intake of fresh air for combustion.
- Make sure the living space is completely isolated from the combustion system of the refrigerator.
The completed installation must:
Installation Manual 3
- Make sure there is complete and unrestricted ventilation of the 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
bafes and panel construction.
Certied installation needs one lower intake vent and one upper exhaust vent. Install the upper exhaust vent either through the roof or
through the side wall of the vehicle exactly as written in this manual. Any other installation method voids both the certication 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
oor level. This allows any leaking propane gas to escape to the outside and not to collect at oor level.
CSA International certication allows the refrigerator to have zero (0) inch minimum clearance at the sides, rear, top, and bottom. While
there are no maximum clearances specied for certication, the following maximum clearances are necessary for correct refrigerator
performance:
Bottom 0 inch min. 0 inch max.
Each Side 0 inch min 1/8 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 the natural air draft that is necessary for good refrigeration. Cooler air
comes in through the lower intake vent, goes up around the refrigerator coils where it removes the excess heat from the refrigerator
components, and goes out through the upper exhaust vent. If this air ow is blocked or decreased, the refrigerator will not cool
correctly.
Each NORCOLD model is certied by CSA International for correct ventilation. Install only the certied vents that are listed in this
manual.
Assemble the Enclosure
1. Make sure the enclosure is:
- 36.56 - 36.69 inches high x 23.69 - 23.82 inches wide x 24 inches deep for N41X models.
- 42.63 - 42.69 inches high x 23.69 - 23.82 inches wide x 24 inches deep for N51X models.
2. Make sure the oor is solid and level.
- The oor must be metal or a wood panel and extend the full width and depth of the enclosure.
- The oor must be able to support the weight of the refrigerator and its contents.
3. Make sure there are no adjacent heat sources such as a furnace vent, a hot water heater vent, etc.
4. If there is more than 1/2 inch between either side of the refrigerator and the inside of the enclosure:
- Fill the space with berglass (batt-type) insulation or add a bafe to eliminate the clearance.
- The rear of the batt-type insulation must be between 18 -19 inches from the face of the enclosure.
- Securely attach the batt-type insulation to the enclosure, so that it remains in this position during refrigerator installation, if it
becomes wet, and in windy conditions.

Install the Lower and Upper Vents
1. Using the following chart, decide which vents and rough opening (RO) sizes to use.
Certied Vent P/N RO Height RO Width
Upper Roof Exhaust Vent 622293 24 in. 5 1/4 in.
Upper Side Exhaust Vent 617485 7 1/4 in. 18 in.
Lower Side Intake Vent 617484 9 3/4 in. 19 3/8 in.

2. Install the lower intake vent (See Art01608):
NOTICE
!
WARNING
- Make sure the bottom of the opening of lower intake vent is even with or
immediately below the oor level.

!
CAUTION
NOTICE
- If the design of the vehicle allows, install the roof exhaust vent [12] directly
The lower intake vent is also the service access opening for the
components on the rear of the refrigerator.

vent is even with or immediately below the oor level. This
allows any leaking propane gas to escape to the outside
and not to collect at oor level.
Make sure that no sawdust, insulation, or other construction
debris is on the refrigerator or in the enclosure. Debris can
cause a combustion hazard and prevent the refrigerator from
operating correctly.
Tighten the screws of the upper roof exhaust cap to 10 inch-pounds
max. Also make sure that the air ow around the upper roof exhaust
cap is not blocked or decreased by other roof mounted features
such as a luggage carrier, an air conditioner, a solar panel, etc.

- Put one bafe between the top rear edge of the refrigerator and the
inside edge of the upper exhaust vent opening.
- Make sure there is less than 1/4 inch clearance [15] between the
bafe and the top of the refrigerator.
- Put the other bafe between the outside edge of the upper exhaust
vent opening and the side wall of the vehicle.
- If you install the upper side exhaust vent (See Art01637):

the rough opening for the upper exhaust vent is at least 41 3/4 inches or poor
cooling performance can occur.
- For N51X models, make sure the distance [25] from the oor level to the
top of the rough opening for the upper exhaust vent is at least 47 3/4
inches or poor cooling performance can occur.
