High altitude installation
Your DESA direct-vent fireplace has been tested and approved for elevations from 0-2,000 feet and certified for elevations from 0-5,000 feet.
Fireplaces for High Altitude (models ending in HA) are for installation above 4,000 feet only. These fireplaces are equipped with parts specific for higher altitudes. IMPORTANT: These fire- places can NOT be converted to propane/LP gas. When installing a non-high altitude fireplace at an elevation above 2,000 feet (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 (Canada), check with local authorities.
Consult with your local gas company to help de- termine the proper orifice size and identification for your location.
Components and parts must be ordered by part number through your local dealer or distributor.
IMPORTANT: For horizontal installations above 2,000 feet, it is recommened that a 12" extension pipe be added before starter elbow (see Figure 30).
