HIGH ALTITUDE INSTALLATION
Your DESA direct-vent fireplace has been tested and approved for
elevations from 0-2000 feet (USA) and elevations from 0-4500
feet (Canada) .
When installing this fireplace at an elevation above 2000 feet (in
the USA), 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.
When installing this fireplace at an elevation above 4500 feet (in
Canada), check with local authorities.
Consult your local gas company to help determine the proper orifice
for your location.
For assistance with any high altitude installation contact DESAʼs
