Chimneys
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 or roof support halfway
up the offset. If penetrating a wall, install
a wall radiation shield (see Figures 34 and
36).
3. Use another elbow to turn the chimney verti-
cally. 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 section Chimney Instal-
lation Instructions) .
5. From below, install a firestop (See Figure
29a).
6. A support (ST
*
or SO+
*
) must be used on
the first 15’ section (5 m).
7. Continue with the regular installation.
AC Chimney
*
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 34).
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
29c) .
6. Continue with the regular installation.
NOTE: When using AC chimney, an AC6SB
*
starter section must be used before installing
an elbow. When an offset is needed imme-
diately off the top of the fireplace, an elbow
starter section, AC6SB30
*
, is available.
