VERTICAL THRU THE ROOF APPLICATIONS
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.
TO INSTALL VERTICAL VENTING
Fig. 29 If there is a room above ceiling level,
firestop spacer must be installed on both the
bottom and the top side of the ceiling joists. If an
attic is above ceiling level a 7DVAIS (Attic
Insulation Shield) must be installed.
Fig. 30 The enlarged ends of the vent section
always face downward.

c) A minimum of an 8 ft. vertical rise.
d) Two sets of 45 degree elbow offsets within these
vertical installations. From 0 to a maximum of 8 ft. of
vent pipe can be used between elbows. (Fig. 25)
e) 7DVCS must be used to support offsets. (Fig. 26)
This application will require that you first determine the
roof pitch and use the appropriate starter kit. (See
Venting Components List)
The minimum height of the vent above the highest
point of penetration through the roof is 2 feet. See
