HIGH ALTITUDE INSTALLATION
Your DESA direct-vent fireplace has been tested and
approved for elevations from 0-2,000 feet (USA)
and elevations from 0-4,500 feet (Canada).
When installing this fireplace at an elevation
above 2,000 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 1,000 feet above sea level. Check with
your local gas company for proper orifice size
identification.
When installing this fireplace at an elevation
above 4,500 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.
