3. Place the first chimney length on the fireplace. Secure the chimney length to the fireplace with the three screws
provided.
The chimney must extend at least 3' above its point of contact with the roof and at least 2' higher than any wall,
roof, or building within 10' of it. If the chimney is higher than 5' above the roof, it must be secured using a roof
brace.
4. At the roof, install a roof radiation shield. The roof radiation shield must be installed so it extends 1" above the
roof line.
5. Put the roof flashing into place.
•
If the chimney is enclosed to the roof: use a vented flashing
•
If the chimney is not enclosed to the roof: use a regular flashing.
6. Seal the joint between the roof and the flashing with roofing tar. 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.
7. Place the storm collar over the chimney and flashing. Seal it around the chimney with silicone sealer (
DO NOT
use roofing tar
).
8. Fit the rain cap on the chimney. Secure it tightly in place.
