High Altitude Installation

Your DESAdirect-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.
