Fireplace Installation

Selecting location

To determine safest and most efficient location for fireplace, you must take into consideration the following guidelines:

1.Location must allow for proper clearances (see Figures 1 and 2).

2.Consider a location where fireplace will not be affected by drafts, air conditioning ducts, windows or doors.

3.A location that avoids 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 7).

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

Minimum/Maximum Chimney Height

Minimum height of chimney, measured from base of fireplace to flue gas outlet of termination, is 11.5 feet for straight flue or a flue with one elbow set. Maximum distance between elbows is 2 feet. For systems with two elbow sets, minimum height is 22 feet. Maximum height of any system is 28 feet.This measurement includes fireplace, chimney sections and height of termination assembly at level of flue gas outlet (see Figure 18, page 11).

Framing

1.Frame opening for fireplace using 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, fireplace must be installed upon a metal or wood panel extending full width and depth of fireplace.

3.Set fireplace directly in front of this opening and slide unit back until nailing flanges touch side framing.

4.Check level of fireplace and shim with sheet metal if necessary.

5.Before securing fireplace to prepared framing, ember protector must be placed between hearth extension (not included) and under bottom front edge of fireplace to protect against glowing embers falling through. If fireplace is to be installed on a raised platform, a Z-typeember protector (not included) must be fabricated to fit your required platform height. Ember protector should extend under fireplace a minimum of 11/2". Ember protector should be made of galvanized sheet metal (28 gauge minimum) to prevent corrosion.

6.Using screws or nails, secure fireplace to framing through flanges located on sides of fireplace.

Hearth Extension

A hearth extension projecting a minimum of 20" in front of and a minimum of 12" beyond each side of fireplace opening is required to protect combustible floor construction in front of 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 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 covered, use noncombustible material such as tile, slate, brick, concrete, metal, glass, marble, stone, etc. Provide a means to prevent hearth extension from shifting and seal gap between fireplace frame and hearth extension with a noncombustible material (see Figure 3).

Woodwork such as wood trims, mantels or any other combustible material projecting from front face must not be placed within 12" of fireplace opening (and within 9" of top louver opening). Combustible materials above 12" and projecting more than 1 1/2" from fireplace must not be placed less than 12" from top opening of fireplace (NFPA STD 211, Sec.7-3.3.3).
