VERTICAL THRU THE ROOF APPLICATIONS

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)

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.

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.

TYPICAL STRAIGHT-UP INSTALLATION
