will help you in piece by piece installation
alignment. Next, extend
bottom flashing past chimney sides

areas and bend extended portions
around to sides of chimney (see
dashed line in detail. Fasten flashing

chimney 2 to 3 inches. At the lower
area, trim flashing flush with chimney.
At the top area where the flashing
extends past the chimney back,
notch flashing at corner and bend
remainder around to the back of the
chimney (as shown at right). Fasten
flashing along your pre-instalIation
