HIGH ALTITUDE INSTALLATION
Your FMI PRODUCTS, LLC direct-vent
fireplace has been tested and approved for
elevations from 0-2,000 feet (USA).
When installing a non-high altitude fireplace at
an elevation above 2,000 feet (USA), you may
need to decrease the input rating by changing
the existing burner orifice to a smaller size.
Reduce input 4% for each 1,000 feet above
sea level. Check with your local gas company
for proper orifice size identification.
IMPORTANT:
For horizontal installations
above 2,000 feet, it is recommended that a
12" extension pipe be added before starter
elbow (see Figure 33).
