Vertical (Through the Roof)
Vent Assembly
NOTE: All vertically terminated installations must, where specified, use the 2¹⁄₄” restrictor plate, to comply with Vertical Termination Window (Fig. 8, Page 9), included in the hardware bag. The plate must be installed within the firebox inner flue collar to insure a proper air/fuel ration is maintained in an appliance vented through the roof. (Fig. 39)

Fig. 39 Install restrictor plate and starter pipe/inner elbow assembly.
Make certain the vent system conforms to all other requirements for vertical termination as specified on Page 9.
This installation will require you to first determine the roof pitch and use the appropriate vent components. Refer to Figure 9, Page 10.
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 (4”) flue collar from the ceiling above, and mark that location.
3.Cut the opening: (Fig. 31, Page 20)
9³⁄₈” x 9³⁄₈” (240mm x 240mm)
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 1” (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. 40) 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. 41)

8.Install appropriate pipe sections until the vent run reaches above the flashing. The enlarged ends of the vent sections always face downward.
9.Install the storm collar and seal around the joints. (Fig. 41)
10.Add additional vent lengths to achieve the proper overall height.
11.Install termination cap.
