Vermont Casting SDDVRMB manual Vertical Through the Roof Vent Assembly, 9³⁄₈” x 9³⁄₈” 240 x 240mm

Vertical (Through the Roof)

Vent Assembly

NOTE: All vertically terminated installations must, where specified, use the restrictor plate, to com- ply with Vertical Termination Window (Fig. 8, Page 8), included in the hardware bag. The plate must be installed as directed on Page 8, Figure 8.

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 Page 10, Figure 11.

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: (Page 17, Fig. 23)

9³⁄₈” x 9³⁄₈” (240 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. 31) 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. 32)

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. 32)

10.Add additional vent lengths to achieve the proper overall height.

11.Install termination cap.

Vertical Through Existing Chimney

The heater must be vented to the outdoors through an existing masonry or prefabricated fireplace chimney system through the roof.

The heater is approved to be vented to the outdoors through any solid-fuel fireplace chimney that has been constructed or installed in accordance with the na- tional, Provincial/State and local building codes and is constructed of noncombustible materials. For Venting Requirements, refer to Page 10. Refer to Venting Com- ponents on Pages 12 & 13.

Fireplace Vent Termination Clearances

Observe the chimney-top vent termination clearances specified in the instructions provided with those compo- nents. Some considerations are:

•Obstructions or impediments to venting.

•Nearby combustible materials that could come into contact with combustion exhaust gases.

•Other nearby openings within 9” (230 mm) through which exhaust gas could reenter the building.
