ASSEMBLY AND INSTALLATION

DIVERT ROOF RUN-OFF

HHT recommends, where excessive water run-off is
possible, use of one of the two options shown in Figure
29 to prevent water running off the roof and onto/into the
horizontal termination cap.

VERTICAL SIDE WALL INSTALLATION

NOTE: For all top vent vertical through-the-roof
installations, install the supplied flue restrictors
onto the top edge of the firebox flue adapter
according to the Vertical Side wall Installation Flue
Restrictor Chart.
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 combus-
tible or noncombustible, cut opening to size. Figure
30 (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.
NOTE: When using flex vent, the opening will have
to be measured according to the 1/2" (13 mm) rise
in 12" (305 mm) vent run.

4. Using appropriate length of pipe section(s) attach to
stove by twisting collar.
5. Measure the horizontal length requirement including
a 2" (51 mm) overlap, i.e. from the elbow to the out-
side wall face plus 2" (51 mm) (or the distance re-
quired if installing a second 90° elbow). Figure 32

venting with a 1/4" rise for every 12" of run.
