HHT recommends, where excessive water run-off is possible,
use of one of the two options shown in Figure 3.10 to prevent
water running off the roof and onto/into the horizontal
termination cap.
Figure 3.10 - Locate Vent Opening on Wall
Vertical Side Wall Installation:
NOTE: Refer to Figures 2.8 thru 2.10 for restrictor plate
adjustments for vertical vent runs.
1. Locate vent opening on the wall. It may be necessary
to first position the stove and measure to obtain hole
location. Depending on whether the wall is combustible
or noncombustible, cut opening to size, Figure
3.11 (For combustible walls first frame in opening.)
Combustible Walls: Cut a 9" H x 9" W (244 x 244 mm) hole
through the exterior wall and frame as shown, Figure 30.
Noncombustible Walls: Hole opening must be 7" (178
mm) in diameter.
