2. From below, install a firestop (A) supplied by the chimney manufacturer in each ceiling/floor separation
through which the chimney will pass. At the attic level, install a radiation shield from above (C).
3. Follow the chimney's manufacturers' instructions and place the first chimney length on the fireplace.
For all chimneys, you must use an anchor plate (A) supplied by the chimney manufacturer before
installing the first chimney length. Continue installing chimney lengths making sure to lock each length
in place.
4. 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 (not illustrated). (Refer to instructions included with
the support).
5. Then, put the roof flashing (D) in place and seal the joint between the roof and the flashing with roofing
pitch. 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.
6. Place the storm collar (E) over the flashing, and tighten it with the bolt supplied. Finally, seal the joint
between the storm collar and the chimney, using silicone caulking.
7. Install the chimney cap (G).
8. When a ventilated roof flashing is installed, precautions are to be taken not to caulk or seal the
ventilating openings.
