chimneys, place the first chimney length on the fireplace.
To lock it in place, turn ¼ of a turn clockwise. With the AC chimney, you must use a starter section
before installing the first chimney length (figure 30). Continue installing chimney lengths making
sure to lock each length in place.
3.
Every time the chimney passes through a ceiling 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.
4.
Put the roof flashing in place and seal the joint between the roof and the flashing with roofing pitch.
(see figures 31 & 32). 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.
