installation for vertical termina- tion

1.Determine the route your vertical venting will take. If ceiling joist, roof rafters or other framing will obstruct the venting system, consider an offset. Refer to Figure 24 to avoid cutting load bearing members.

For optimal flame appearance, a restrictor disk is necessary on straight vertical runs of 10' of more.

•Runs may not incorporate elbows.

•The disk is part number 56D3027 and is included in installation manual packet.

•Drop the disk into a 5" inner collar before installing the first section of flue or install at the last section before installing the termination.

•Anadditionaldiskmaybeinstalledonrunsof35'ormore. Rotate disks perpendicular to each other.

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. Offsets must fall within the parameters shown in Figures 23 and 24.

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

Drop a plumb line from the inside of the roof to the ceiling locating hole in the ceiling. Mark the center point where the vent will penetrate the roof. Drill a small locating hole at this point.

1.Cut a 101/2" (241 mm) square hole in the ceiling using the locating hole as a center point The opening should be framed to 101/2"x101/2" (241 x 241 mm) inside dimen- sions as shown in Figure 26 using framing lumber the same size as the ceiling joist. If the area above the ceil- ing is an insulated ceiling or a room, nail firestop from the top side. This prevents loose insulation from falling into the required clearance space. Figure 25. Otherwise, install firestop below the framed hole. Figure 26
