1. Install the first elbow; turn it in the required
direction. Fasten it to the chimney with
the three (3) 1/2” (12 mm) metal screws
provided with the elbow.
2. Install the necessary chimney lengths to
achieve the required offset. Lock the chimney
lengths together: it is recommended to use
three (3) 1/2” (12 mm) screws. If the offset
length is made of two (2) chimney lengths
or more, use an offset support halfway up
the offset. If penetrating a wall, install a wall
radiation shield (see
Figures 27 and 28
).
3. Use another elbow to turn the chimney
vertically. Secure the elbow, using three
(3) 1/2” (12 mm) screws (provided with the
elbow).
4. Use a plumb-bob to line up the center of
the hole. Cut a hole for the chimney in the
ceiling/floor. Frame this hole as described
previously (refer to
Chimney Installation
Instructions on
Page 15
).
5. From below, install a firestop (See
Figure
22a
)
.
6. A support (XST+
*
or XSO+
*
) must be used
on the first 15’ section (5 m).
7. Continue with the regular installation.

1. Install the first elbow. Turn it in the required
direction. To lock it in place, turn 1/8 of a
turn. Fasten the straps attached to the elbow
to the surrounding frame, using nails or
drywall screws
(
Figure 27
)
.
2. Install the necessary chimney lengths to
achieve the required offset. Lock the chimney
lengths together. If penetrating a wall, use
a wall radiation shield.
3. Use another elbow to turn the chimney
vertically. Lock it to the chimney. Fasten
the straps attached to the elbow to the
surrounding framing using nails or drywall
screws.
4. Use a plumb-bob to line up the center of the
hole. Cut a hole for the chimney in the ceiling.
Frame this hole as described previously.
5. From below, install a firestop (see
Figure
22b
).
6. Continue with the regular installation.
NOTE: When using ACBI chimney, an ACBI7SB
*
(H3258
*
) starter section must be used before
installing an elbow. When an offset is needed
immediately off the top of the fireplace, an
elbow starter section, ACBI7SB30
*
(H3259
*
)
is available.
