Installation Manual 3
Certification and Code Requirements
Ventilation Requirements
WARNING:
The completed installation must:
- Make sure there is sufficient 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 flue 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
baffles and panel construction.
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.
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:
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 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. If
this air flow is blocked or decreased, the refrigerator will not cool
correctly.
Each NORCOLD model is certified by CSA International for
correct ventilation. Install only the certified vents that are listed in
this manual.
This refrigerator is certified 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:
- 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 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.
