Safety Awareness
Read this manual carefully and understand the contents before
you install the refrigerator.
Be aware of possible safety hazards when you see the safety
alert symbol on the refrigerator and in this manual. A signal
word follows the safety alert symbol and identifies the danger of
the hazard. Carefully read the descriptions of these signal
words to fully know their meanings. They are for your safety.
WARNING: This signal word means a hazard, which if
ignored, can cause dangerous personal injury, death, or
much property damage.
CAUTION: This signal word means a hazard, which if
ignored, can cause small personal injury or much
property damage.
WARNING:
- This refrigerator 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.
- Propane gas can ignite and cause an explosion that can
result in property damage, personal injury, or death. Do
not smoke or create sparks while working on the gas
supply system. Do not use an open flame to examine the
gas supply piping or fittings for leaks.
- To avoid possible propane gas leaks, always use two
wrenches to tighten or loosen the gas suppy line connections.
- Make sure the electrical installation obeys all applicable
codes. See “Certification 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 fire.
- 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 flame. Do not bend, drop, weld, move, drill,
puncture, or hit the cooling system.
Installation Manual 2
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.
Certification and Code Requirements
Ventilation Requirement s
This refrigerator is certified under the latest edition of ANSI
Z21.19 Standards by the American Gas Association for installation in mobile homes or recreational vehicles and is approved by
the Canadian Gas Association.
The installation must obey these standards and this “Installation
Manual” for the NORCOLD limited warranty to be in effect.
Installation must agree with local codes. In the absence of local
codes, the installation must obey these standards:
In the United States:
- National Fuel Gas Code, ANSI Z223.1.
- Manufactured Home Construction and Safety Standard,
Title 24 CFR, Part 32-80.
- Standard for Recreational Vehicles, ANSI 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.
In Canada:
- Current CGA B149.1 and CGA B149.2 Installation Code for
Propane Appliances and Equipment.
- 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.
- When installed, the refrigerator must be electrically
grounded as written in the local or state codes, and 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 24, and in Canada, the current CAN 1-6.10 Standard.
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 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
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.
American Gas Association/Canadian Gas Association (AGA/
CGA) 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
refrigeration:
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 flow is blocked or decreased, the
refrigerator will not cool correctly.
Each NORCOLD model is certified by AGA and CGA for correct
ventilation.
