Vertical (Through the Roof)
Vent Assembly
Note that all vertically terminated installations must include the restrictor plate included with the stove. Refer to Figure 8, Page 8.
Make certain the vent system conforms to all other requirements for vertical termination as specified on Page 8.
This installation will require you to first determine the roof pitch and use the appropriate vent components. Refer to Figures 8 and 9 on pages 8 and 9.
1.Locate the final position of the stove, observing all clearances for both the vent and the stove.
2.Plumb to the center of the inner (4Ó) flue collar from the ceiling above, and mark that location.
3.Cut the opening:
CFM System: 9³⁄₈” x 9³⁄₈” (240mm x 240mm)
DuraVent System: 10” x 10” (254mm x 254mm)
4.Plumb any additional opening through the roof or other construction that may be needed. In all cases, the opening must provide a minimum of 1Ó (25mm) clearance to the vent pipe.
5.Place the stove in its final position.
6.Install firestop(s) #7DVFS and Attic Insulation Shield #7DVAIS as needed. (Fig. 30) If there is a room above ceiling level, a firestop must be installed on both the bottom and top sides of the ceiling joists. If an attic is above ceiling level, an attic insulation shield must be installed.

7.Install the appropriate roof support and flashing, making certain that the upper flange of the flashing base is below the shingles. (Fig. 31)
8.Install appropriate pipe sections until the vent run reaches above the flashing. The enlarged ends of the vent sections always face downward.
