Figure 16 - Installing Firestop
If area above is a living space, install
firestop below framed hole.
If area above is an attic or insulated area,
install firestop above framed hole.
Note: If vent pipe passes through any occupied ar-
eas above first floor, including storage spaces and
closets, you must enclose pipe. You may frame
and sheetrock enclosure with standard construc-
tion material. Make sure and meet the minimum
allowable clearances to combustibles. Do not fill
any required air spaces with insulation.

HIGH ALTITUDE INSTALLATION
Your DESA Heating, LLC direct vent fireplace
has been tested and approved for elevations
from 0-2000 feet.
Fireplaces for high altitude (DVF-36AN(H,S)-S
and DVF-42AN(H,S)-S) are for installations
above 4,000 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, 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, check with local authorities.
