Vertical Through-the-Roof Installation

1. Locate your fireplace.
2. Plumb to center of the (8") flue collar from ceiling
above and mark position.
3. Cut opening equal to 14¹⁄₂" x 14¹⁄₂" (368 mm x 368
mm).
4. Proceed to plumb for additional openings through
the roof. In all cases, the opening must provide a
minimum of 1¹⁄₂" (38 mm) clearance to the vent pipe,
i.e., the hole must be at least 14¹⁄₂" x 14¹⁄₂" (368 mm
x 368 mm).
5. Place fireplace into position.
6. Place firestop(s) SKFS2A or Attic Insulation Shield
AIS-SK into position and secure. (Figs. 30, 31)
7. Install roof support (Fig. 32) and roof flashing making
sure upper flange of flashing is below the shingles.
8. Install appropriate pipe sections until the venting is
above the flashing.
9. Seal around the pipe.
10. Add additional vent lengths for proper height. (Fig.
