CHIMNEY INSTALLATION INSTRUCTIONS
1. Cut and frame the holes in the ceiling,
floor and roof where the chimney will pass
(see Figure 19). Use a plumb-bob to line
up the center of the holes. The hole sizes
are indicated in Table 3 for the floor and
ceiling holes and in Table 4 (Page 17) for
the roof holes.
Figure 19
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 (see Figures
20A and 20B).
3. For ASHT+ and S-2100+ chimneys, place
the first chimney length on the fireplace. To
lock it into place, turn 1/4 of a turn clock-
wise. With the AC chimney you must use
a starting section before installing the first
chimney length (see Figure 21). Continue
installing chimney lengths making sure to
lock each length in place.
4. Every time the chimney passes through a
roof or a wall, install the appropriate firestop.
When you reach the desired height, install
the roof support (see 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. 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 (Figures 22
and 23).
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.
