HIGH ALTITUDE INSTALLATION
Your Ironhaus 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.
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.
