6. Continue to add pipe sections until the
height of the vent cap meets the minimum
building code requirements described in
Figure 7 on page 8.
Note:
You must in-
crease vent height for steep roof pitches.
Nearby trees, adjoining rooflines, steep
pitched roofs and other similar factors
may cause poor draft or down-drafting
in high winds. Increasing the vent height
may solve this problem.
7. Twist-lock the vent cap onto the last sec-
tion of vent pipe.
Note:
If the vent pipe passes through any oc-
cupied areas above the first floor, including
storage spaces and closets, you must enclose
pipe. You may frame and sheetrock the en-
closure with standard construction material.
Make sure and meet the minimum allowable
clearances to combustibles. Do not fill any of
the required air spaces with insulation.
