Read these important instructions carefully. Become thoroughly acquainted with the
content before installing vents and refrigerator.
IMPORTANT NOTE: Norcold's Venting and Installation instructions must be followed.
These Upper and Lower Side Vent Installation instructions are in addition to Norcold's
Ventilation and Installation instructions that accompany each refrigerator. Follow the Venting
and Installation instructions when installing the refrigerator. Installation must conform with local
codes, or in the absence of local codes, with 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.
In Canada:
- Current CGA B149.1 and CGA B149.2 installation code for Propane Appliances and Equip-
ment.
- 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 in accord with local or state codes,
the National Electrical code, and ANSI/NFPA 70. In Canada, grounding is in accord with the
Canadian Electrical Code C22.2.
LP Gas supply piping and fittings must comply with local, state, and national codes governing type
and size. These components should also comply with the current NFPA 501C section 2.41, 1990
and with the current CAN 1-6.10 Standard.
Important!
During storage of the refrigerator in the RV or the trailer, always disconnect the power
source.
