4.3.3 CHIMNEY INSTALLATION INSTRUCTIONS
1. Cut and frame the holes in the ceiling, floor and roof where the chimney
will pass and install radiation shields (see figure X). 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.
Important: roof radiation shield is mendatroy for all installations!
2. From below, install a firestop supplied by the chimney manufacturer in
each ceiling/floor separation through which the chimney will pass. At the
attic level, install an attic radiation shield from above.
3. Follow the chimney’s manufacturers’ instructions and place the first
chimney length on he fireplace. For all chimneys, you must use an anchor
plate supplied by the chimney manufacturer before installing the first
chimney length (see figure 24). Continue installing chimney lengths mak-
ing 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. (Refer to instructions included with the support.
5. Then, put the roof flashing in place and seal the joint between the roof
and the flashing with roofing pitch (see figures 24). 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 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.
8. When a ventilated roof flashing is installed, precautions are to be taken
not to caulk or seal the ventilating openings.
