chimneys, place the first chimney length on
the fireplace. To lock it in place, turn 1/4 of
a turn clockwise. With the AC chimney, you
must use a starter section before installing
the first chimney length (Figure 31). Con-
tinue installing chimney lengths making sure
to lock each length in place.
3. Every time the chimney passes through a ceil-
ing or a wall, install the appropriate firestop.
When you reach the desired height, install the
roof support (refer to instructions included
with the support). For an AC chimney use
an universal support AC10SU (H3265).
4. Put the roof flashing in place and seal the
joint between the roof and the flashing with
roofing pitch (see Figures 32 and 33). For
sloping roofs, place the flashing under the
upper shingles and on top of the lower
shingles. Nail the flashing to the roof, using
roofing nails.
5. Place the storm collar over the flashing, and
tighten it with the bolt supplied. Finally, seal
the joint between the storm collar and the
chimney, using silicone caulking.
6. Install the chimney cap.
