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 DESA's Customer Service Department at
1-866-672-6040.
