1. Cut and frame the holes in the ceiling, floor and roof where the chimney will pass. Use a plumb
bob to line up the center of the holes. Make sure that the size of the floor and ceiling holes are
in accordance with the chimney manufacturer’s instructions.
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.
