selecting location
To determine the safest and most efficient location for the fireplace, you must take into consideration the following guidelines:
1.The location must allow for proper clearances (see Figures 1 and 2).
2.Consider a location where the fireplace will not be affected by drafts, air conditioning ducts, windows or doors.
3.A location that avoids the cutting of joists or roof rafters will make installation easier.
4.Anoutsideairkitisavailablewiththisfireplace
(see Optional Outside Air Kit on page 8).

WARNING: Do not pack required air spaces with insulation or other materials.
Minimum/Maximum Chimney Height for
Residential Installation
The minimum height of the chimney, measured from the base of the fireplace to the flue gas outlet of the termination, is 14.5 feet for straight flue or a flue with one elbow set. The maximum distance between elbows is 6 feet. For systems with two elbow sets, the minimum height is 22 feet. The maximum height of any system is 50 feet. This measurement includes the fireplace, chimney sec- tions and the height of the termination assembly at the level of the flue gas outlet (see Figure 18, page 11).
Minimum/Maximum Chimney Height for
Outdoor Installation
The minimum height of the chimney, measured from the base of the fireplace to the flue gas outlet of the termination, is 7 1/2 feet (minimum of 4 feet of chimney pipe sections required for outdoor installation).
Framing
1.Frame the opening for the fireplace using the dimensions shown in Figures 1 and 2.
2.If the fireplace is to be installed directly on carpeting, tile (other than ceramic) or any combustible material other than wood floor- ing, the fireplace must be installed upon a metal or wood panel extending the full width and depth of the fireplace.
3.Set the fireplace directly in front of this open- ing and slide the unit back until the nailing flanges touch the side framing.
4.Check the level of the fireplace and shim with sheet metal if necessary.
5.Before securing fireplace to prepared fram- ing, the ember protector (provided) must be placed between the hearth extension (not supplied) and under the bottom front edge of the fireplace to protect against glowing embers fallingthrough.Ifthefireplaceistobe installed on a raised platform, a Z-type ember protector (not supplied) must be fabricated to fit your required platform height. The ember protector should extend under the fireplace a minimumof11/2".Theemberprotectorshould be made of galvanized sheet metal (28 gauge minimum) to prevent corrosion.
6.Using screws or nails, secure the fireplace to the framing through flanges located on the sides of the fireplace.

For outdoor installations, the fireplace enclosure must allow for adequate drainage and fresh air ventilation.Itisrecommendedthatasealed,corro- sionresistantcatchpanwithprovisionfordrainage beinstalledunderthefireplacewithinthefireplace enclosure (see Accessories on page 16).
Hearth Extension
A hearth extension projecting a minimum of 16" in front of and a minimum of 8" beyond each side of the fireplace opening is required to protect combustible floor construction in front of the fire- place.Fabricateahearthextensionusingamaterial which meets the following specifications: a layer of noncombustible, inorganic material having a thermal conductivity of K=0.84 BTU IN/FT, HR. F (or less) at 1" thick. For example, if the material selected has a K factor of 0.25, such as glass fiber, the following formula would apply:
0.25 x 1.0" = 0.30" thickness required
0.84
Thermal conductivity "K" of materials can be obtained from the manufacturer or supplier of the noncombustible material. If the hearth extension istobecovered,usenoncombustiblematerialsuch as tile, slate, brick, concrete, metal, glass, marble, stone, etc. Provide a means to prevent the hearth extension from shifting and seal gap between the fireplace frame and hearth extension with a non- combustible material (see Figure 3).

Mantels
A mantel may be installed if desired (see Figure 4). Woodwork such as wood trims, mantels or any other combustible material projecting from the front face must not be placed within 12" of the fireplace opening. Combustible materials above 12" and projecting more than 11/2" from the fireplace must not be placed less than 15" from the top opening of the fireplace (NFPA STD 211, Sec. 7-3.3.3).
Mantels or any other combustible material also may come up to the side edge of the black metal face of the fireplace just as long as the projection from the front face fall within the limit shown in Figure 4.

Optional Outside air Kit
(Model ak4/ak4f)
The installation of an outside air kit should be per- formed during the rough framing of the fireplace due to the nature of it's location. Outside combus- tion air is accessed through a vented crawl space (AK4F) or through a sidewall (AK4).
CAUTION: Combustion air inlet ducts shall not terminate in attic space.
Secure to Collars with Metal Tape, Screws or Straps (Min. of 1/4" x 20" in size)

Chimney Pipe
The DESA chimney system consists of 12", 18", 24", 36" and 48" snap-lock, double-wall pipe segments, planned for maximum adaptability to individual site requirements. Actual lengths gained after fitting overlaps must be taken into consideration (lineal gain) and are given in the lineal gain chart (see Figure 6). Lineal gain is the actualmeasurablelengthofapartaftertwoormore partsareconnected.ForCanada,usechimneyparts designated "HT".
WARNING: The opening in the collar around the chimney at the top of the fireplace must not be obstructed.Neveruseblowninsulation to fill the chimney enclosure.
