Safety Continued Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning resemble the flu, with headaches, dizziness or nausea. If you have these signs, the fireplace may not be working properly. Get fresh air at once! Have fireplace serviced. Some people are more affected by carbon monoxide than others. These include pregnant women, people with heart or lung disease or anemia, those under the influence of alcohol and those at high altitudes.
Safety Continued 1. For propane/LP fireplace, do not place propane/LP supply tank(s) inside any structure. Locate propane/LP supply tank(s) outdoors. To prevent performance problems, do not use propane/LP fuel tank of less than 100 lb. capacity. 2. If you smell gas • shut off gas supply • do not try to light any appliance • do not touch any electrical switch; do not use any phone in your building • immediately call your gas supplier from a neighbor’s phone.
Product Identification Flue Collar Outer Glass Door Herringbone Brick Refractories Nailing Flange Log Set Grate Lower Door/ Control Cover Figure 1 - Direct Vent Fireplace Product Features These are a few facts that can help you understand and enjoy your direct vent fireplace: • 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).
Pre-installation Location and space requirements Determine the safest and most efficient location for your direct vent fireplace. 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 fireplace and termination cap.
Pre-Installation Continued Clearances Minimum clearances to combustibles for the fireplace are as follows: *Back and sides 1" Perpendicular walls 6" Floor 0" Ceiling to louver opening 42" Front 36" Top of Standoffs 0" Vent (See venting instructions for specific venting clearances.) Combustible material with a maximum thickness of 5/8" may be flush with the top front of fireplace. * For back and sides of fireplace, do not pack with insulation or other materials.

Venting Installation NOTICE: Read these instructions 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 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.
Venting Installation Continued 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. 1. Set fireplace in its desired location and determine the route your horizontal venting will take.
Venting Installation Continued 5. Noncombustible Exterior Wall: Position horizontal vent cap in center of the 8 1/2" 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: Four wood screws provided should be replaced with appropriate fasteners for stucco, brick, concrete or other types of sidings (see Figure 10).

Drill a small locating hole at this point. 3. 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. 4. Roof Flashing 5. Wall Strap 45° Elbow 6.
Venting Installation Continued High Altitude Installation Note: If vent pipe passes through any occupied areas above first floor, including storage spaces and closets, you must enclose pipe. You may frame and sheetrock enclosure with standard construction material. Make sure and meet the minimum allowable clearances to combustibles. Do not fill any required air spaces with insulation. Vertical Termination Configurations Figure 17 shows the configurations for vertical termination.
Fireplace Installation CHECK GAS TYPE Use proper gas type for the fireplace unit you are installing. If you have conflicting gas types, do not install fireplace. See retailer where you purchased the fireplace for proper fireplace according to your gas type. Installing Gas Piping to Fireplace Location WARNING: A qualified service person must connect fireplace to gas supply. Follow all local codes. CAUTION: For propane/LP units, never connect fireplace directly to the propane/LP supply.
Fireplace Installation Continued Check your building codes for any special requirements for locating equipment shutoff valve to fireplaces. Apply pipe joint sealant lightly to male NPT threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged fireplace valves. WARNING: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas. We recommend that you install a sediment trap/drip leg in supply line as shown in Figure 19.
Fireplace Installation Continued CHECKING GAS CONNECTIONS WARNING: Test all gas piping and connections, internal and external to unit, for leaks after installing or servicing. Correct all leaks at once. WARNING: Never use an open flame to check for a leak. Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak. Correct all leaks at once. Pressure Testing Gas Supply Piping System Test Pressures In Excess Of 1/2 PSIG (3.5 kPa) 1.
Fireplace Installation Continued 3. Make sure control knob of fireplace is in the OFF position. 4. Check all joints from equipment shutoff valve to gas valve (see Figure 22 or Figure 23, page 18).

Turn equipment shutoff valve counterclockwise to the ON position. Do not force. 8. Replace center brick/control cover. 9.
Inspecting Burners Check pilot flame pattern and burner flame patterns often. PILOT Assembly The pilot assembly is factory preset for the proper flame. Alterations may have occurred during shipping and handling. The pilot is located on right hand side of burner. The flame must envelope 1/4" of top of the ignitor/sensor and grounding stem.
Cleaning and Maintenance Continued Glass must be cleaned periodically. During start-up it is normal for condensation to form on the inside of the glass causing lint, dust and other airborne particles to cling to the glass surface. During initial start-up a slight film may form on the glass due to paint curing. The glass should be cleaned several times with a non-ammonia, nonabrasive household cleaner and warm water after the first two weeks of operation.
Troubleshooting WARNING: Turn off fireplace and let cool before servicing. Only a qualified service person should service and repair fireplace. CAUTION: Never use a wire, needle or similar object to clean pilot. This can damage pilot unit. Note: All troubleshooting items are listed in order of operation.
