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 50 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-type ember protector (not included) must be fabricated to fit your required platform height. Ember protector should extend under fireplace a minimum of 1 1/2". 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 16" in front of and a minimum of 8" 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).
WARNING:Hearthextension

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 must be assembled independently as chimney 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.
Note: For Canada, use chimney parts designated HT.
Opening in collar around chimneyattopoffireplacemust not be obstructed. Never use blown insulation to fill chimney enclosure.
Continue to assemble chimney sections as outlined, making sure that both inner and outer pipe sections are locked together. When

installing double wall snap-lock chimney 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 11, page 9).
Using ELBOW offsets (30E-8DM)
1.To achieve desired offset, you may install combinations of 12", 18", 24", 36" and 48" length of double wall pipe (see offset chart, page 7, and Figure 9).
Note: For systems with 2 elbow sets, minimum height is 22 feet. Maximum height for any system is 50 feet.
2.Chimney weight above offset rests on return elbow. Straps must be securely nailed to rafters or joists (see Figure 10, details A and B, page 9).
3.Maximum length of pipe between supports (return elbow or 12S-8DM) is 6' of angle run. Maximum of two 6' angle run sections per chimney system (see Figure 9).
4.All pipe connections between offset and return must be secured with two screws on outer pipe only (see Figure 11, page 9). Do not penetrate inner stainless.

Firestop Spacers (V3600FS-8DM)
Firestop spacers are required at each point where chimney penetrates a floor space. Their purpose is to establish and maintain required clearance between chimney and combustible materials. When pipe passes through a framed opening into a living space above, firestop must be placed onto ceiling from below as shown in Figure 12.
They also provide complete separation from one floor space to another or attic space as required by most codes. When double wall pipe passes through a framed opening into an attic space, firestop must be placed into an attic floor as shown in Figure 13.
If area above is a living space, install firestop below framed hole.
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 roof.

Flashing installation (v6f8dm or v12f-8dm)
Determine flashing to be used with roof opening chart. Slide flashing over pipe until base is flat against roof. Replace as many shingles as needed to cover exposed area and flashing base. Secure in position by nailing through shingles (see Figure 15, page 11). DO NOT NAIL THROUGH FLASHING CONE.
Installing Flashing on a Metal Roof
When installing flashing on a metal roof, it is required that putty tape be used between flashing and roof. Flashing must be secured to roof using #8 x 3/4" screws and then sealed with roof coating to prevent leakage through screw holes. A roof coating must also be applied around perimeter of flashing to provide a proper seal.

Finishing fireplace
Combustible materials, such as wallboard, gypsum board, sheet rock, drywall, plywood, etc., may make direct contact with sides and top around fireplace face. It is important that combustible materials do not overlap face itself. Brick, glass, tile or other noncombustible materials may overlap front face provided they do not obstruct essential openings such as louvered slots. When overlapping with a noncombustible facing material, use only noncombustible mortar or adhesive.

Note: Before you proceed, make sure your gas supply is turned off.
Use only a 1/2" black iron pipe and appropriate fittings.
1.Remove knockout indentation on refractory or firebrick wall located above refractory hearth floor. Knockout indentation must be firmly tapped with any solid object, such as a 1/2" dowel, until it is released. Remove fragmented portions of refractory (see Figure 21).
2.Remove gas line cover plate located on either side of fireplace and pull out insulation from gas line conduit sleeve. Save insulation for reuse.
3.Run a 1/2" black iron gas line into fireplace through rear at gas line conduit sleeve (if using a raised platform, add height). Provide sufficient gas line into fireplace chamber for fitting connection (see Figure 22).
Note: Secure incoming gas line to wood framing to provide rigidity for threaded end.
4.Repack insulation around gas line and into sleeve opening. Seal any gaps between gas line and refractory knockout hole with refractory cement or commercial furnace cement. Install gas appliance or cap off gas line if desired.
CAUTION:Allgaspipingand connections must be tested for leaks after installation is completed. After ensuring that gas valveis on,apply soapandwater solution to all connections and joints. Bubbles forming show a leak. Correct all leaks at once.

WARNING: If the fireplace has been used for wood burning, firebox and chimney must be cleaned of soot, creosote and ashes be a qualified chimney cleaner. Creosote will ignite if heavily heated.
WARNING: When using a decorative vented gas log, damper must be removed or permanentlylockedinfullyopen position and glass doors must be in fully open position.
Glass Doors
Glass doors are optional with this fireplace. When fireplace is in operation, doors must be fully opened or fully closed position only or a fire hazard may be created (see Figure 23).
A fireplace equipped with glass doors operates much differently than a fireplace with an open front. A fireplace with glass doors has a limited amount of air for combustion. Excessive heat within fireplace can result if too large a fire is built or if combustion air gate is not completely open.
The following tips should be used to assure that both fireplace and glass door retain their beauty and function properly. Both the flue damper and glass doors must be fully opened before starting a fire. This will provide sufficient combustion air and maintain safe temperatures in firebox.
IMPORTANT: The glass must be allowed to warm slowly and evenly. Tempered glass will withstand a gradual temperature rise to 550° F, which is more than a normal fire will generate. Such materials as pitch/wax laden logs, very dry mill end lumber and large amounts of paper or cardboard boxes can create an excessively hot fire and should not be burned in this fireplace. Always keep fire back from doors and never allow flames to contact glass.
WARNING: Fireplaces equipped with glass doors should be operated only with doors fully opened or doors fully closed. Doors, if left partly open, may draw gas and flame out of the fireplace opening creating risks of both fire and smoke.
Doors Fully Closed
Fireplace Front
Doors Fully Opened

Figure 23 - Glass Doors
Cleaning Glass
Clean glass with any commercial glass cleaner or soap and water. Do not use any abrasive material to clean the glass. Do not clean glass with any cool water if glass is still hot from fire and smoke.
A gas line or gas log lighter may be installed for the purpose of installing a vented or ventfree decorative gas appliance incorporating an automatic shutoff device and complying with the Standard for Decorative Gas Appliances for Installation in Vented Fireplaces, ANSI Z21.60 or American Gas Association draft requirements for Gas Fired Log Lighters for Wood Burning Fireplaces, Draft NO. 4 dated
August, 1993.
If you wish to install an unvented (vent-free) gas log set, only unvented gas log sets which have been found to comply with the standard for unvented room heaters,ANSI Z21.11.2 are to be installed in this fireplace.
