HIGH ALTITUDE INSTALLATION

Your DESA International direct-vent fireplace has been CSA 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 International’s Customer Service Department at 1-866-672-6040.
