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 cut- ting 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 fireplace in desired location. Drop a plumb line down from the ceiling to the posi- tion of the fireplace exit flue. 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.

1. Cut a 10 3/4" square hole in the ceiling using the locating hole as a center point. The open- ing should be framed to 10 3/4" x 10 3/4" inside dimensions, as shown in Figure 9 on page 10 using framing lumber the same size as the ceiling joists. If the area above the ceiling is an insulated ceiling or an attic, nail firestop from the top side. This prevents loose insula- tion from falling into the required clearance space. If the area above the ceiling is a living space, install firestop below the framed hole. The firestop 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 fireplace flue up through the firestop. Be sure all pipe and elbow connections are fully twist-locked (see Figure 8, page 10).

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 3/4" x 10 3/4" 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 10.

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

Note: If an offset is needed to avoid obstruc- tions, you must support the vent pipe every 3 feet. Use wall straps for this purpose (see Fig- ure 19). Whenever possible, use 45° elbows instead of 90° elbows. The 45° elbow offers less restriction to the flow of the flue gases and intake air.

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

If area above is a living space, install firestop below framed hole.
