Firebox Installation
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 extend the fireplace any distance into the room. A projection may be ideal for a new addition on an existing, finished wall.

WARNING: Do not block required air spaces with insulation or any other material. Do not obstruct effective open- ing* of firebox with any type of facing material. Combustible material must not be in contact with black front face of firebox.
*(The effective opening is considered the opening where actual heat output may occur.)

Mantel Clearances
Woodwork such as wood trims, mantels or any other combustible material projecting from the front face must not be placed within 9" of firebox effective opening.
Combustible materials above and projecting more than 1 1/2" from the firebox front face (see Figure 4, page 5) must not be placed less than 12" from effective opening of the firebox (NFPA STD 211, Sec.
Mantels or any other combustible material may also come up to the side edge of the black metal face of the firebox only if the projection from the front face falls within limits shown in Figure 5, page 5.
