SELECTING LOCATION
To determine the safest and most efficient
location for the firebox, you must take into
consideration the following guidelines:
1. The location must allow for proper clear-
ances.
2. Consider a location where the heat output
will not be affected by drafts, air condition-
ing ducts, windows or doors.
3. A location that avoids the cutting of
joists or roof rafters will make installation
easier.
4. If an outside air kit is to be installed, ac-
cessibility to outside combustion air must
be considered. This can also be achieved
through a vented crawl space in some
cases (see
Optional Outside Air Kit
on
page 6).
5. Do not connect this firebox to a chimney
system other than a DESA Heating, LLC
chimney system.
6. Install in an area providing ventilation and
adequate combustion air.
7. Due to high temperatures, do not locate
this firebox in high traffic areas or near
furniture or draperies.
8. Provide adequate clearances around
air openings into combustion chamber.
NEVER obstruct front opening of firebox
or flow of combustion and ventilation air.
9. Do not locate in or near an area where
gasoline or other flammable liquids may
be stored. The firebox area must be kept
clear and free from these combustible
materials.
The typical installation for this fireplace is a
projected installation which allows you to ex-
tend the fireplace any distance into the room.
A projection may be ideal for a new addition
on an existing, finished wall.
