Vertical (Through The Roof) Vent Assembly - Vermont Castings Stardance 3070 Homeowner's Installation And Operating Manual

Vermont Castings Stardance Direct Vent/Natural Vent Gas Heater
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 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:
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 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. 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.
