2. From below, install a firestop in each ceiling/
floor separation through which the chimney
will pass. At the attic level, install an attic
radiation shield from above ( Figures 22a
and 22b ) .
3. For Secure Temp

/ Secure Temp GX chimneys
*
,
place the first chimney length on the fire-
place. To lock it in place, turn 1/4 of a turn
clockwise. With the ACBI chimney, you must
use a starter section before installing the
first chimney length ( Figure 23 ) . 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. When installing a
support, slightly lift the chimney system so
the weight will lie on the support, not on the
fireplace to reduce expansion noises (Refer
to instructions included with the support).
For an ACBI chimney
*
use an universal
support AC10SU

.
5. Put the roof flashing in place and seal the
joint between the roof and the flashing with
roofing pitch (see Figures 24 and 25 ) . 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. Once the chimney
cap is in place, the roof flashing can be
washed with a solvent or vinegar and then
painted with rust-proof paint.
