CHIMNEY INSTALLATION INSTRUC-
TIONS
1. Cut and frame the holes in the ceiling, fl oor
and roof where the chimney will pass (see
Figure 22). Use a plumb bob to line up the
center of the holes. The sizes are indicated
in Table 2 for the fl oor and ceiling holes
and Table 3 (Page 15) for the roof holes.

From below, install a fi restop in each ceiling/fl oor
separation through which the chimney will pass.
At the attic level, install an attic radiation shield
from above (Figures 23a & 23b).
2. For Secure Temp S2100+ / Nova Temp
HT6000+ / Secure Temp GX chimneys, place
the fi rst chimney length on the fi replace.
To lock it in place, turn 1/4 of a turn clock-
wise. With the ACBI chimney, you must
use a starter section before installing the
fi rst chimney length (Figure 24). Continue
installing chimney lengths making sure to
lock each length in place.
3. Every time the chimney passes through a ceil-
ing or a wall, install the appropriate fi restop.
When you reach the desired height, install the
roof support (Refer to instructions included
with the support). For an ACBI chimney use
an universal support AC10SU.
4. Put the roof fl ashing in place and seal the
joint between the roof and the fl ashing
with roofi ng pitch (see Figures 25 & 26).
For sloping roofs, place the fl ashing under
the upper shingles and on top of the lower
shingles. Nail the fl ashing to the roof, using
roofi ng nails.
5. Place the storm collar over the fl ashing, and
tighten it with the bolt supplied. Finally, seal
the joint between the storm collar and the
chimney, using silicone caulking.
6. Install the chimney cap.
