To Install Vertical Venting

VERTICAL THRU THE ROOF APPLICATIONS

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)

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.
