CHIMNEY INSTALLATION INSTRUC-
TIONS
1. Cut and frame the holes in the ceiling, floor
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 floor and ceiling holes
and Table 3 (Page 15) for the roof holes.
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 23a & 23b).
2. For Secure Temp S2100+ / Nova Temp
HT6000+ / Secure Temp GX chimneys, place
the first chimney length on the fireplace.
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
first 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 firestop.
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 flashing in place and seal the
joint between the roof and the flashing
with roofing pitch (see Figures 25 & 26).
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.
5. 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.
6. Install the chimney cap.
