Vertical Through-the-Roof Installation

1. Locate your fireplace.
2. Plumb to center of the (4”) flue collar from ceiling

above and mark position.

3. Cut opening equal to 9³⁄₈” x 9³⁄₈” (240 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 9³⁄₈” x 9³⁄₈” (240 x 240 mm).

5. Place fireplace into position.
6. Place firestop(s) #7DVFS or Attic Insulation Shield

#7DVAIS into position and secure. (Fig. 41)

7. Install roof support (Fig. 42) and roof flashing making

sure upper flange is below the shingles. (Fig. 44)

8. Install appropriate pipe sections until the venting is

above the flashing. (Fig. 44)

9. Install storm collar and seal around the pipe.
10. Add additional vent lengths for proper height. (Fig.

43)

11. Apply high temperature sealant to 4” and 7” collars

of vertical vent termination and install.

If there is a room above ceiling level, fire stop spacer
must be installed on both the bottom ad the top side
of the ceiling joists. If an attic is above ceiling level a
7DVAIS (Attic Insulation Shield) must be installed.
The enlarged ends of the vent section always face
downward.
