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, page 6).
Minimum clearance to combustibles
Back and sides of fireplace 1 1/2" min.*
Front of fireplace | 48" min. |
Floor** | 0" min. |
Perpendicular wall to opening 12" min. | |
Top spacers | 0" min. |
Mantel clearance | see Mantels, |
| page 5 |
Chimney outer pipe surface 2" min.
* Not required at nailing flanges ** See step 2 of Framing
WARNING: Do not pack requiredairspaceswithinsulation 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 opening for fireplace using the dimensions shown in Figures 1 and 2.
2.If fireplace is to be installed directly on carpeting, tile (other than ceramic) or any combustible material other than wood flooring, 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 opening and slide unit back until nailing flanges touch side framing.
4.Check the level of fireplace and shim with sheet metal if necessary.
5.Before securing fireplace to prepared framing, the ember protector (provided) must be placed between hearth extension (not supplied) and under bottom front edge of fireplace to protect against glowing embers falling through. If the fireplace is to be installed on a raised platform, a
mum 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.

Fireplace Installation
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).
WARNING:Hearthextension
is to be installed only as shown
in 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.
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 performed during the rough framing of the fireplace due to the nature of it's location. Outside combustion 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.

Firestop Spacers
Firestop spacers are required at each point where the chimney penetrates a floor space. Their purpose is to establish and maintain the required clearance between the chimney and the combustible materials. When the pipe passes through a framed opening into a living space above, the firestop must be placed onto ceiling from below as shown in Figure 10.
They also provide complete separation from one floor space to another or attic space as required by most codes. When the double wall pipe passes through a framed opening into an attic space, the firestop must be placed into an attic floor as shown in Figure 11.

3.Use the roof opening chart (Figure 12) to determine the correct opening length and flashing required.
4.Remove shingles around the opening measured. Cut out this section.
5.Add next sections of pipe until the end penetrates roof line. Check to see that the proper clearances are maintained. Extend chimney by adding sections of double wall pipe until pipe is minimum of 30" above the highest point of the roof cutout. Termination and chimney must extend a minimum of 36" above the highest point where it passes through the roof.

Installing Flashing on a Metal Roof
When installing the flashing on a metal roof, it is required that putty tape be used between the flashing and the roof.The flashing must be secured to the roof using #8 x 3/4" screws and then sealed with roof coating to prevent leakage through the screw holes. A roof coating must also be applied around the perimeter of the flashing to provide a proper seal.
Storm Collar Installation
Place storm collar over pipe and slide down until it is snug against the open edge of the flashing (see Figure 14). Apply waterproof caulk around the perimeter of the collar to provide a proper seal.

Instructions for chase installations are included with the chase style termination chosen. In a multiple chase installation, be sure to provide adequate distance between terminations to prevent smoke spillage from one termination to another. Terminations be separated a minimum of 24" center to center and stacked at a minimum vertical height difference of 18" (see Figure 16).
Note: If a decorative shroud is to be installed, contact the manufacturer for specifications.
