Vertical (Through the Roof) Vent Assembly
Note that all vertically terminated installations must include the restrictor plate included
with the stove.
Make certain the vent system conforms to all other requirements for vertical termination as
specified. This installation will require you to first determine the roof pitch and use the
appropriate vent components. Refer to Figures 36 and 37.
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 100mm(4") flue collar from the ceiling above, and mark that
location.
3. Cut the opening:
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) and Attic Insulation Shield as needed. (Fig. 36) 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. 37)
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. 37)
10. Add additional vent lengths to achieve the proper overall height.
11. Apply cement to the inner and outer termination collars and install the terminal cap.
