TO INSTALL VERTICAL VENTING

1. Locate your fireplace.
2. Plumb to centre of the (4") flue collar from ceiling
above and mark position.
3. Cut opening equal to 9-3/8" x 9-3/8" (240 mm x 240 mm).
4. Proceed to plumb for additional openings through the
roof. In all cases, the opening must provide a minimum
of 1 inch clearance to the vent pipe, i.e., the hole must
be at least 9-3/8" x 9-3/8" (240 mm x 240 mm).
5. Place fireplace into position.
6. Place firestop(s) #7DVFS or Attic Insulation Shield
#7DVAIS into position and secure. (Fig. 29)
7. Install roof support (Fig. 27) and roof flashing making
sure upper flange of flashing is below the shingles. Fig. 30.
8. Install appropriate pipe sections until above the flash-
ing. (See Fig. 30).
9. Install storm collar and seal around the pipe.
10. Add additional vent lengths for proper height. Fig. 28.
11. Apply high temperature sealant to 4" and 7" collars of
vertical vent termination and install.
