HIGH ALTITUDE INSTALLATION
Your cast iron stove and direct-vent burner
system has been tested and approved for
operation at altitudes from 0-2000 ft.
When installing this stove at an elevation
above 2000 feet, you may need to decrease
the input rating by changing the existing
burner orifice to a smaller size. Reduce input
4% for each 1000 feet above sea level. Check
with your local gas company for proper orifice
size identification and proper orifice for your
location.

stallation contact FMI PRODUCTS, LLC at
