VENTING INSTallaTION
INSTRUCTIONS
Continued
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 increase 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 section
of vent pipe.
Note: If the vent pipe passes through any occupied
areas above the first floor, including storage spaces
and closets, you must enclose pipe. You may
frame and sheetrock the enclosure 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.
