Horizontal installations using roundtermination require exterior portion of wall firestop (see Figure14, page 10).1. Set the fireplace in its desired location and determine the routeyour horizontal venting will take. Do not secure the fireplaceuntil all venting has been installed. Some installations requiresliding the fireplace in and out of position to make final vent-ing connections. Figures 14 through 18 on pages 10 through12 show different configurations for venting with horizontaltermination that will help you decide which application bestsuits your installation. Check to see if wall studs or roof raftersare in the path of your desired venting route. If they are, youmay want to adjust the location of the fireplace.2. Direct vent pipe sections and components are designed withspecial twist-lock connections.Twist-Lock Procedure: The female ends of the pipes havelocking lugs (indentations). These lugs will slide straight intomatching slots on the male ends of adjacent pipes. Push pipesections together and twist one section clockwise approxi-mately one-quarter turn until the sections are fully locked (seeFigure 8). Note: Horizontal runs of vent must be supportedevery three feet. Use wall straps for this purpose.3. Use a 45° elbow to connect venting system to fireplace fluecollar. The elbow is designed to be twist-locked onto the fluecollar as described in step 2. IMPORTANT: Do not attemptto alter the configuration of the elbow by cutting, twisting,bending, etc.4. Assemble the desired combination of pipe and elbows to thefireplace flue collar. If there are long portions of venting run,pre-assembled pipe sections may be installed as subassembliesfor convenience.5. Carefully determine the location where the vent pipe assemblywill penetrate the outside wall. The center of the hole shouldline up with the center-line of the horizontal vent pipe. Mark thewall for a 10 3/4" x 10 3/4" square hole. Cut and frame the squarehole in the exterior wall where the vent will be terminated. Ifthe wall being penetrated is constructed of noncombustiblematerial, such as masonry block or concrete, a 8 1/2" hole withzero clearance is acceptable (see Figure 9).VENTING INSTALLATIONINSTRUCTIONSContinuedVENTING INSTALLATION INSTRUCTIONSInstallation PlanningFigure 8 - Vent Pipe ConnectionsFigure 9 - Vent Opening RequirementsCenterof HoleFemaleLockingLugsMaleSlots
