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 Figure 2).

2.Consider a location where the heat output 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.If an outside air kit is to be installed, accessibility 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).

The typical installation for a (V)3612ST 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.

Fireplace Installation

Continued

2.If fireplace is to be installed directly on carpeting, tile (other than ceramic) or any combustible material other than wood flooring, fireplace must be installed upon a metal or wood panel extending full width and depth of fireplace.

3.Set fireplace directly in front of 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, ember protector (provided) must be placed between hearth extension (not supplied) and under bottom front edge of fireplacetoprotectagainstglowingembers falling through (see Figure 7). If 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 (see Figure 6). The ember protector should extend under 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 fireplace to the framing through flanges located on sides of the fireplace (see Figure 8).

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 fireplace (see Figure 9, page 6).

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 manufacturer or supplier of noncombustible material.

If hearth extension is to be raised, a “Z” type ember protector must be used (see Figure 6 and Figure 10, page 6)

Chimney Pipe

The FMI PRODUCTS, LLC chimney is a snap-lock,double-wallpipe. It consists of a stainless steel inner flue pipe(s), a galvanized outer pipe and a wire spacer.

Each section of pipe comes in lengths of 12",

18" 36" and 48". The actual lineal gain for each is measured after each section is fully connected. Lineal gain is the actual measurable length of a part after two or more parts are connected.

Pipe Installation

The pipe sections must be assembled independently as the chimney is installed. When connecting chimney directly to the fireplace, theinnerfluepipesectionmustbeinstalledfirst 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 fireplace starter. The wire will assure the proper spacing between the inner and outer pipe sections.

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

Figure 17, page 8).

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.

Using ELBOW offsets and Supports

Chimney weight above offset rests on return elbow. Straps must be securely nailed to rafters or joists (see Figure 15, page 8).

To achieve desired offset, you may install combinations of 12", 18", 36" and 48" length of double wall pipe (see offset chart and Figure 16, page 8).

The chimney support section is a 4" strap and 12" length of pipe. A chimney support is required every 30 feet above fireplace after a straight chimney run or above a return elbow after a straight chimney run (see Figure 17, page 8). This support is designed to relieve the extra weight load on fireplace and elbows

when high chimneys are installed.

Firestop Spacers (FS-10)

Firestop spacers are required at each point where the chimney penetrates a floor or ceiling joist 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 the ceiling from below as shown in Figure 19, page 9.

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 20, page 9.

When penetrating a floor or ceiling at an angle, use firestop spacer number 30 FS-

10D (see Replacement and Accessory Parts, page 15).

Uncommon circumstances such as neighboring hills, tall trees, or strong wind areas can cause down drafts in chimney system. In such cases, going beyond the minimum recommended height would be preferable to provide a better draw.

The fireplace height approved for any chimney run with this fireplace system is 40 feet measured from bottom of fireplace to flue

Penetrating Roof

To maintain a 2" clearance to pipe on a roof with a pitch, a rectangular opening must be cut.

1.Determine the center point through which pipe will penetrate roof.

2.Determine center point of roof. Pitch is the distance the roof drops over a given span, usually 12". A 6/12 pitch means that the roof drops 6" for each 12" one measure horizontally down from roof rafters.

3.Use roof opening chart (Figure 23) to determine correct opening length and flashing required.

4.Remove shingles around opening measured. Cut out this section.

5.Add next sections of pipe until end penetrates roof line. Check to see that proper clearances are maintained. Extend chimney by adding sections of double wall pipe until pipe is minimum of 30" above highest point of roof cutout. Termination and chimney must extend a minimum of

36" above highest point where it passes through the roof.
