• This DESA fireplace and its components are safe when installed according to this installation manual. Unless you use DESA components, which have been designed and tested for the fireplace system, you may cause a fire hazard.
• The DESA warranty will be voided by and DESA disclaims any responsibility for the following actions.
a. Modification of the fireplace, components,
doors, air inlet system and damper control.
b. Use of any component part not manufac
tured or approved by DESA in combination
with a DESA fireplace system. Proper installation is the most important step in ensuring safe and continuous operation of the fireplace. Consult the local building codes as to the particular requirements concerned with the installation of all factory built fireplaces.
WARNING: Do not install a fireplace insert in this box unless the manufacturer's instructions with the insert specifically state this fireplace has been tested for use with this insert.
FOR YOUR SAFETY
• Do not store or use gasoline or any other flammable vapors or liquids in the vicinity of this or any other appliance.
• Due to high temperatures, the appliance should be located out of traffic and away from furniture and draperies.

FIREPLACE INSTALLATION

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. An outside air kit is available with this fireplace (see Optional Outside Air Kit on page 6).
MINIMUM CLEARANCE TO COMBUSTIBLES
Back and sides of fireplace 3/4" minimum*
Floor** 0" minimum
Perpendicular wall to opening 12" minimum
Top spacers 0" minimum
Mantel clearances
Chimney outer pipe surface 1" minimum
* Not required at nailing flanges ** See step 2 of Framing
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 8 feet (minimum of 4 feet of chimney pipe sections required for outdoor installation).
see Mantels, page 5
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 falling through. If the fireplace is to be 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 minimum of 1 1/2". The ember protector should 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.

Note: For outdoor installations, the fireplace en­closure must allow for adequate drainage and fresh air ventilation. It is recommended that a sealed, corrosion resistant catch pan with provision for drainage be installed under the fireplace within the fireplace enclosure.
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. Fabricate a hearth extension using a material
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 1 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

VENTING INSTALLATION

OPTIONAL OUTSIDE AIR KIT (MODEL AK4/AK4F)
The installation of an outside air kit should be per­formed 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)
Air Inlet Location Must Allow For Bushes or Snow

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 actual measurable length of a part after two or more parts are connected. For Canada, use chimney parts designated "HT".
WARNING: The opening in the collar around the chimney at the top of the fireplace must not be obstructed. Never use blown insula­tion to fill the chimney enclosure.

ASSEMBLY AND INSTALLATION OF DOUBLE WALL CHIMNEY SYSTEM
Each double wall chimney section consists of a galvanized outer pipe, a stainless steel inner flue pipe and a wire spacer. The pipe sections must be as­sembled independently as the chimney is installed. When connecting chimney directly to the fireplace, the inner flue pipe section must be installed first with the lanced side up. The outer pipe section can then be installed over the flue pipe section with the hemmed end up. Press down on each pipe section until the lances securely engage the hem on the fire place starter. The wire will assure the proper spacing between the inner and outer pipe sections.
