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 8), 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. 32)

5.Place the stove in its final position.

6.Install firestop(s) #7DVFS and Attic Insulation Shield #7DVAIS as needed. (Fig. 33) 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. 34)
