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)
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.
IMPORTANT: For horizontal installations
above 2,000 feet, it is recommened that a 12"
extension pipe be added before starter elbow
(see Figure 33).
