Place the Finish Collar around the support and fasten it to the ceiling
using the screws provided.
3. Attach the flue extension (found in the support box) to the bottom of the
first chimney length using the 3 metal screws provided. Put this
chimney length in the support. Push it down firmly in place.
4. Use a regular roof flashing. Put the roof flashing in place. Place the
flashing under the upper shingles and on top of the lower shingles -
approximately half of the flashing should be under the shingles. Seal
the joint between the roof and the flashing with roofing tar or silicone.
Nail the flashing to the roof using roofing nails. Place the storm collar
over the chimney and flashing. Caulk the joint between the chimney
and collar with silicone caulking.
5. Put the remaining required lengths of chimney in place. Fasten the
lengths together using three metal screws at each joint (provided with
the chimney). If the chimney extends more than 5 feet above the roof,
install a roof brace.
6. Fit the rain cap to the top of the chimney. Screw the four metal screws
provided through the straps and into the top chimney length.
SUPPORT EXTENSIONS - ROUND (ERDSE) OR SQUARE (ESSE)
Steep pitched cathedral ceilings, or attics with greater than average
insulation depth, may require the use of a support extension. This piece fits
down inside the support and can be adjusted to increase the support's
length by up to 22". The extension is attached to the support using the
eight metal screws provided. Be sure there is at least a 2 inch overlap
where the extension joins the support.
