Installation

selecting Fireplace 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 5).

WARNING: Do not pack required air spaces with insulation or other materials.

Minimum/Maximum Chimney Height

The minimum height of the chimney, measured from the base of the fireplace to the flue gas outlet of the termination, is 16 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 sections and the height of the termination assembly at the level of the flue gas outlet (see Figure 15, page 9).

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 including wood flooring, the fireplace must be installed

on a hearth spacer designed for use with this fireplace (see Replacement and Accessory Parts, page 18).

3.Set the fireplace directly in front of this opening 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.Beforesecuringfireplacetopreparedframing,theemberprotector(provided)mustbe 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.Theember protector shouldextend

underthefireplaceaminimumof1 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.

Hearth Extension

A hearth extension projecting a minimum of

20" in front of and a minimum of 12" beyond each side of the fireplace opening is required to protect combustible floor construction in front of the fireplace. Fabricate a hearth extension using a material 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 is to be covered, use noncombustible material such 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 noncombustible 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 1 1/2" 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)

Installation of an outside air kit should be performed during rough framing of fireplace due to nature of it's location. Outside combustion air is accessed through a vented crawl space (AK4F) or through a sidewall (AK4). This fireplace is equipped with a barometric damper which allow outside air to flow into fireplace automatically when needed.

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. Pipe sections mustbeassembledindependentlyaschimney is installed. When connecting chimney directly to fireplace, inner flue pipe section must be installed first with lanced side up. Outer pipe section can then be installed over flue pipe section with hemmed end up. Press down on each pipe section until lances securely engage hem on fireplace starter. Wire will assure proper spacing between inner and

outer pipe sections.

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.

Continue to assemble chimney sections as outlined above, making sure both inner and outer pipe sections are locked together. When installing double wall snap-lockchimney together, it is important to assure joint between chimney sections is locked. Check by pulling chimney upward after locking. Chimney will not come apart if properly locked. It is not necessary to add screws to keep chimney

together (exception, see Figure 9, page 8).

2. Chimney weight above offset rests on return elbow. Straps must be securely nailed to rafters or joists (see Figure 8, details A and B).
3. Maximumlengthofpipebetweensupports (return elbow or 12S-12DM) is 6' of angle run. Maximum of two 6' angle run sections per chimney system (see Figure 7).
4. All pipe connections between the offset and return must be secured with two screws on the outer pipe only (see Figure 9, page 8). Do not penetrate the inner stainless.
