Effects of High Altitude on Propane Gas
Operation
When you operate the refrigerator on propane gas at altitudes
higher than 5500 feet above sea level:

refrigerator.
- You may experience burner outages.
To avoid these possible problems, Norcold recommends that
you operate the refrigerator on AC when at altitudes higher than
5500 feet above sea level.
