HIGH ALTITUDE INSTALLATION
Your DESA direct-vent fireplace 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 fireplaces are equipped with parts specific
for higher altitudes. IMPORTANT: These fireplac-
es can NOT be converted to Propane/LP gas.
When installing a non-high altitude 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.
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.
