HIGH ALTITUDE INSTALLATION
Your DESA direct-vent replace has been tested and
approved for elevations from 0-2000 feet (USA) and
elevations from 0-4500 feet (Canada).
Fireplaces for High Altitude (models ending in
-HA) are for installation above 4000 feet only.
These replaces are equipped with parts specic
for higher altitudes. IMPORTANT: These replac-
es can NOT be converted to Propane/LP gas.
When installing a non-high altitude replace at an
elevation above 2000 feet (in the USA), you may
need to decrease the input rating by changing the
existing burner orice to a smaller size. Reduce
input 4% for each 1000 feet above sea level. Check
with your local gas company for proper orice
size identication.
When installing this replace at an elevation above
4500 feet (in Canada), check with local authorities.
IMPORTANT: For horizontal installations
above 2,000 feet, it is recommended that a 12"
extension pipe be added before starter elbow
(see Figure 25, page 18) and a round horizontal
termination be used.
