DANGER:Carbonmonoxide poisoning may lead to death!
This fireplace must be installed by a qualified (certified or licensed) service person. It has a sealed gas combustion chamber that uses a coaxial pipe (pipe within a pipe and having the same center) venting system. It brings in fresh air for combustion through the outer pipe and combustion gases are exhausted through the inner pipe. If the glass door assembly and venting pipe are not properly seated, connected and sealed, carbon monoxide leakage (spillage) can occur.

These are a few facts that can help you understand and enjoy your direct-vent fireplace:
•The venting system may be routed to the outsideofyourhomeinseveralways.Itmay vent through the roof (vertical) or it may vent to an outside/exterior wall (horizontal). The vent pipe installation is very important to allow for proper operation. You must follow the venting instructions very carefully for either vertical or horizontal applications.
•This fireplace may be installed in any room of your house provided all local codes and these installation instructions are followed.
•This fireplace does not require electricity to operate.
•Only the blower requires electricity if installed. If you plan to install the blower at a later date, outlet must be wired at the bottom of the fireplace when framing.
•Apiezo ignitor and ceramic electrode create sparks to ignite the pilot light. It does not require any matches, batteries or any other sources of ignition to light the pilot.
•Each time you turn on your fireplace, you may notice some amount of condensation on the inside of the fireplace glass. This is normal and will disappear after 10-20 minutes of operation.
•Your direct-vent gas fireplace system (fireplace and venting) is a balanced and

NOTICE: Read these instructionscompletelybeforeattempting installation.
These models are tested and approved for use with FMI PRODUCTS, LLC (direct-vent) pipe components and terminations.
The venting system must terminate on the outside of the structure and can not be attached to a chimney or flue system serving a separate solid fuel or gas burning appliance. A direct-vent appliance must have its own venting system. DO NOT common vent this appliance.
These models are approved to be vented either horizontally through an outside wall or vertically through a roof or chase enclosure using the following guidelines:
•When venting system terminates horizontally on an outside wall, you may install a standoff if the termination cap is to be installed directly on a combustible finish such as vinyl, wood, stucco, etc.
•Never run the vent downward as this may cause excessive temperatures which could cause a fire.
•Vent pipe air space clearances to combustibles are 1" on all sides except on the horizontal sections, which requires 2" clearance from the top of the pipe. Where the termination cap penetrates a combustible wall, 1" air space clearance is required.
•Snorkel terminations are required when minimum clearance to grade cannot be met (see Figure 16 on page 12).
•Have fireplace and selected vent components on hand to help determine the exact measurements when elbowing or offsetting. Always use wall firestops when penetrating walls and firestops when penetrating ceilings or attic spaces.
•If using a venting configuration of only horizontal venting with no vertical run, a 1/4" rise for every 12" of run toward the termination is required.
•For installation of fireplace at elevations of 4000 feet or greater, pay special attention to venting requirement recommendations.
WARNING: Read all instructionscompletelyandthoroughly before attempting installation.
Failure to do so could result in seriousinjury,propertydamage or loss of life.
NOTICE:Failuretofollowtheseinstructions will void the warranty.
NOTICE: Do not seal vent cap to pipe. Cap must be removable for service.
Installation Precautions
•Wear gloves and safety glasses for protection
•Use extreme caution when using ladders or when on roof tops
•Be aware of electrical wiring locations in walls and ceilings
The following actions will void the warranty on your venting system:
•Installation of any damaged venting component
•Unauthorizedmodificationoftheventingsystem (Do not cut or alter vent components)
•Installation of any component part not manufactured or approved by FMI PRODUCTS, LLC
•Installation other than as instructed by these instructions
WARNING: This gas fireplace andventassemblymustbevented directlytotheoutside.Theventing system must NEVER be attached to a chimney serving a separate solidfuelburningappliance.Each direct-ventgasappliancemustuse aseparateventsystem.Donotuse common vent systems.
WARNING:Ventpipeairspace clearances to combustibles are
1" on all sides except on the horizontal sections, which require 2" clearances from the top of the pipe. Where the termination cap penetrates a combustible wall, 1" air space clearance is required.

INSTALLATION PLANNING
There are two basic types of direct-vent installation:
•Horizontal Termination
•Vertical Termination
Horizontal Termination Installation
IMPORTANT: Horizontal square terminations require only inner portion of wall firestop. Horizontal installations using round termination require exterior portion of wall firestop available only in vent kit HTK (see Figure 14, page 11).
1.Set fireplace in its desired location and determinetherouteyourhorizontalventing will take. Do not secure fireplace until all venting has been installed. Some installations require sliding fireplace in and out of position to make final venting connections. Figures14through18onpages11through 13showdifferentconfigurationsforventing withhorizontalterminationthatwillhelpyou decide which application best suits your installation. Check to see if wall studs or roof rafters are in the path of your desired venting route. If they are, you may want to adjust the location of the fireplace.
5.Carefully determine location where vent pipe assembly will penetrate the outside wall.The center of hole should line up with center line of horizontal vent pipe. Mark wall for a 11 1/2" x 11 1/2" square hole. Cut and frame the square hole in exterior wall where vent will be terminated. If wall being penetrated is constructed of noncombustible material, such as masonry block or concrete, a 8 1/2" hole with zero clearance is acceptable (see Figure 9).
WARNING: Do not recess vent termination into any wall. This will cause a fire hazard.
Female Locking Lugs
Male
Slots
2.Direct vent pipe sections and components are designed with special twist-lock connections.
Twist-Lock Procedure: Female ends of pipes have locking lugs (indentations). These lugs will slide straight into matching slots on male ends of adjacent pipes. Push pipe sections together and twist one section clockwise approximately onequarter turn until sections are fully locked (see Figure 8). Note: Horizontal runs of vent must be supported every three feet. Use wall straps for this purpose.
3.Use a 45° elbow to connect venting system to fireplace flue collar. The elbow is designed to be twist-locked onto flue collar as described in step 2. IMPORTANT: Do not attempt to alter configuration of elbow by cutting, twisting, bending, etc.
4.Assemble desired combination of pipe and elbows to fireplace flue collar. If there are long portions of venting run, preassembled pipe sections may be installed as subassemblies for convenience.

6.Noncombustible Exterior Wall: Position horizontal vent cap in center of the 8 1/2" round hole and attach to exterior wall with fourscrews(seeFigure10). Note: The four wood screws provided should be replaced with appropriate fasteners for stucco, brick, concrete or other types of sidings. Before attaching vent cap to exterior wall, run a bead of non-hardening mastic (pliable sealant) around outside edges to make a seal between it and outside wall.
Combustible Exterior Wall: For vinyl siding, stucco or wood exteriors, a siding standoff may be installed between vent cap and exterior wall. Siding standoff prevents excessive heat from damaging siding materials. Siding material must be cut to accommodate standoff. Bolt vent cap to standoff. Apply non-hardening mastic around outside edge of standoff. Position standoff/cap assembly in center of the 11 1/2" square hole and attach to exterior wall with wood screws provided (see Figure 11). Siding standoff must sit flush against exterior fascia material.
7.Connecting Vent Cap with Horizontal Vent Pipe: Slide wall firestop over vent pipe before connecting horizontal run to vent cap (see Figure 12).
Carefully move fireplace, with vent assembly attached, toward wall and insert vent pipe into horizontal termination. The pipe overlap should be a minimum of 1 1/4" (see Figure 13, page 11).

installation for vertical termination
Note: Vertical restrictor must be installed in all vertical installations.
1.Determine route your vertical venting will take. If ceiling joists, roof rafters or other framing will obstruct venting system, consider an offset (see Figure 19) to avoid cutting load bearing members. Note: Pay special attention to these installation instructions for required clearances (air space) to combustibles when passing through ceilings, walls, roofs, enclosures, attic rafters, etc. Do not pack air spaces with insulation. Also note maximum vertical rise of venting system and any maximum horizontal offset limitations.
2.Set fireplace in desired location. Drop a plumb line down from ceiling to position of fireplace exit flue. Mark center point where vent will penetrate ceiling. Drill a small locating hole at this point.
Drop a plumb line from inside of roof to locating hole in ceiling. Mark center point where vent will penetrate roof. Drill a small locating hole at this point.

If area above ceiling is a living space, install firestop below framed hole.Firestopshouldbeinstalledwithnoless than 3 nails per side (see Figure 20).
2.Assemble desired lengths of pipe and elbows necessary to reach from fireplace flue up through firestop. Be sure all pipe and elbow connections are fully twistlocked (see Figure 8, page 9).
3.Cut a hole in roof using locating hole as a center point. (Cover any exposed open vent pipes before cutting hole in roof.)The
111/2" x 11 1/2" hole must be measured on the horizontal; actual length may be larger depending on pitch of roof. There must be a 1" clearance from vent pipe to combustible materials. Frame opening as shown in Figure 9, page 9.
4.Connect a section of pipe and extend up through hole.
Note: If an offset is needed to avoid obstructions, you must support vent pipe every 3 feet. Use wall straps for this purpose (see Figure 19). Whenever possible, use 45° elbows instead of 90° elbows. The
45°elbowofferslessrestrictiontotheflow of flue gases and intake air.
5.Place flashing over pipe section(s) extending through roof. Secure base of flashing to roof and framing with roofing nails. Be sure roofing material overlaps top edge of flashing as shown in Figure
19.There must be a 1" clearance from vent pipe to combustible materials.
