PRODUCT FEATURES

These are a few facts that can help you understand and enjoy your direct-vent replace:

• The venting system may be routed to the outside of your home in several ways. It may 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 replace may be installed in any room of your house provided all local codes and these installation instructions are followed.

111986-01G4

PRODUCT FEATURES

• This replace does not require electricity to operate.

• Only the blower requires electricity if installed and if you plan to install the blower at a later date, do not forget to wire the outlet at the bottom of the replace when framing.

• A piezo ignitor and ceramic electrode create spark 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 replace, you may notice some amount of condensation on the inside of the replace glass. This is normal and will disappear after 10-20 minutes of operation.

• Your dire ct-vent gas fireplace system (replace and venting) is a balanced and sealed gas operating unit. It requires approximately 10-20 minutes of operating time before the ame pattern stabilizes.

PRE-INSTALLATION

PREPARATION

LOCATION AND SpACE REqUIREMENTS

Determine the safest and most efcient location for your FMI PRODUCTS, LLC direct-vent replace. Make sure that rafters and wall studs are not in the way of the venting system. Choose a location where the heat output is not affected by drafts, air conditioning ducts, windows or doors. Figure 2 shows some common locations. Be aware of all restrictions and precautions before deciding the exact location for your replace and termination cap.

When deciding the location of your replace, follow these rules:

• Do not connect this replace venting to a chimney ue serving a separate solid-fuel burning replace or appliance.

• Due to high temperatures, do not locate this replace in high trafc areas, windy or drafty areas or near furniture or draperies.

• Proper clearances must be maintained.

• If your replace is to be installed directly on carpeting, vinyl tile or any combustible material other than wood, it must be installed on a metal or wood panel extending the full width and depth of the replace. See Figure 3.

111986-01G 5

www.fmiproducts.com

• Your replace is designed to be used in zero clearance installations. Wall or framing material can be placed directly against any exterior surface on the back, sides or top of your replace, except where standoff spacers are integrally attached. If standoff spacers are attached to your replace, these spacers can be placed directly against wall or framing material. See framing details on page 6.

• If you plan on installing a television or enterta in ment center recessed above your replace, it is recommended that you maintain a minimum 18" above top of louver opening.

• When locating termination cap, it is important to observe the minimum clearances shown in Figure 7, page 7.

• If recessing into a wall, you can avoid extra framing by positioning your replace against an already existing framing member.

• Do not recess termination cap into a wall or siding.

• You may paint the termination cap with 450º F (232º C) heat-resistant paint to coordinate with the exterior nish.

• There must not be any obstruction such as bushes, garden sheds, fences, decks or utility buildings within 24" from the front of the termination cap.

• Do not locate termination cap where excessive snow or ice build up may occur. Be sure to clear vent termination area after snow falls to prevent accidental blockage of venting system. When using snow blowers, do not direct snow towards vent termination area.

VENTING INSTALLATION

NOTICE: Read these instruc-

tions completely before attempting 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 ue 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 nish such as vinyl, wood, stucco, etc.

• Never run the vent downward as this may cause exc essive tem pe ratures whic h could cause a re.

• 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 replace and selected vent components on hand to help determine the exact measurements when elbowing or offsetting. Always use wall restops when penetrating walls and restops when penetrating ceilings or attic spaces.

• If using a venting conguration of only horizontal venting with no vertical run, a 1/4" rise for every 12" of run toward the termination is required.

WARNING: Read all instruc-

tions completely and thoroughly before attempting installation.

Failure to do so could result in

serious injury, property damage or loss of life.

www.fmiproducts.com

NOTICE: Failure to follow these in-

structions will void the warranty.

NOTICE: Do not seal termination

cap to vent pipe. Cap must be removable for vent inspection and maintenance.

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

• Unauthorized modication of the venting system (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 replace and vent assembly must be vented directly to the outside. The venting system must NEVER be attached to a chimney serving a separate solid fuel burning appliance. Each direct-vent gas appliance must use a separate vent system. Do not use common vent systems.

WARNING: Vent pipe air space 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 restop. Horizontal installations using round termination require exterior portion of wall restop available only in vent kit HTK (see Figure 14, page 11).

1. Set replace in its desired location and determine the route your horizontal venting will take. Do not secure replace until all venting has been installed. Some installations require sliding replace in and out of position to make nal venting connections. Figures 14 through 18 on pages 10 through 13 show different congurations for venting with horizontal termination that will help you 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 location of replace.

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 replace ue collar. The elbow is designed to be twist-locked onto the ue collar as described in step 2.

IMPORTANT: Do not attempt to alter

conguration of elbow by cutting, twisting, bending, etc.

4. Assemble desired combination of pipe and elbows to replace ue collar. If there are long portions of venting run, preassembled pipe sections may be installed as subassemblies for convenience.

111986-01G 9

Continued

5. Carefully determine the location where vent pipe assembly will penetrate outside wall. The center of hole should line up with center line of horizontal vent pipe. Mark wall for a 10" x 10" square hole. Cut and frame 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 7 3/4" hole with zero clearance is acceptable (see Figure 9).

Continued

WARNING: Do not recess

vent termination into any wall. This will cause a re hazard.

6. Noncombustible Exterior Wall: Posi- tion horizontal vent cap in the center of 7

/4" round hole and attach to exterior wall with four wood screws provided. 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.

Note: The four wood screws provided should be replaced with appropriate fasteners for stucco, brick, concrete or other types of sidings.

Combustible Exterior Wall: For vinyl

siding, stucco or wood exteriors, a siding standoff may be installed between vent cap and exterior wall. The 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 the center of the 10" square hole and attach to exterior wall with wood screws provided (see Figure 11). Siding standoff must sit ush against exterior fascia material.

7. Combustible Exterior Wall Only: Slide wall restop over vent pipe before connecting horizontal run to vent cap (see Figure 12).

8. Carefully move replace, with vent assembly attached, toward wall and insert vent pipe into horizontal termination. Pipe overlap should be a minimum of 1 Figure 13, page 11).

9. Combustible Exterior Wall Only: Slide wall restop against interior wall surface and attach with screws provided. See Figure 13, page 11, for horizontal termination details.

10. Place replace into position and shim with noncombustible material if needed. Nail or screw side anges to framing to secure unit in place. IMPORTANT: Make sure re- place is level before securing. If replace is not level it will not work properly.

VENTING INSTALLATION

INSTALLATION FOR VERTICAL

TERMINATION

Note: Vertical restrictor must be installed in all vertical installations.

1. Determine the route your vertical venting will take. If ceiling joists, roof rafters or other framing will obstruct the 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 the venting system and any maximum horizontal offset limitations.

2. Set the replace in desired location. Drop a plumb line down from the ceiling to the position of the replace exit ue. Mark the center point where the vent will penetrate the ceiling. Drill a small locating hole at this point.

Drop a plumb line from the inside of the

roof to the locating hole in the ceiling. Mark the center point where the vent will penetrate the roof. Drill a small locating hole at this point.

Roof Flashing

Flat Ceiling Installation

Cut a 10" square hole in the ceiling using the locating hole as a center point. The opening should be framed to 10" x 10" inside dimensions, as shown in Figure 9 on page 9 using framing lumber the same size as the ceiling joists. If the area above the ceiling is an insulated ceiling or attic space, nail restop from the top side. This prevents loose insulation from falling into the required clearance space. If the area above the ceiling is a living space, install restop below the framed hole. The restop should be installed with no less than three nails per side (see Figure 20).

2. Assemble the desired lengths of pipe and elbows necessary to reach from the replace ue up through the restop. Be sure all pipe and elbow connections are fully twist-locked (see Figure 8, page 9).

3. Cut a hole in the roof using the locating hole as a center point. (Cover any exposed open vent pipes before cutting hole in roof.) The 10" x 10" hole must be measured on the horizontal; actual length may be larger depending on the pitch of the roof. There must be a 1" clearance from the vent pipe to combustible materials. Frame the opening as shown in Figure 9, page 9.

4. Connect a section of pipe and extend up through the hole.

If area above is an attic or insulated area, install restop above framed hole.
