CHIMNEY INSTALLATION
INSTRUCTIONS
1. Cut and frame the holes in the ceiling, floor
and roof where the chimney will pass (see
Figure 21).
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.
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 ASHT+ / and S2100+ /
chimneys
*
place the first chimney length on
the fireplace. To lock it in place, turn 1/4 of
a turn clockwise. With the AC chimney, you
must use a starter section before installing
the first chimney length
(Figure 23).
Con-
tinue 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).
5. Then, 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 spacers and 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.
