After reaching the location requiring the
elbow, proceed as follows:
ASHT+ / HT6103+ / S-2100+ / HT6000+
Chimneys
1. Install the first elbow; turn it in the required
direction. Fasten it to the chimney with
thethree(3)1/2”(12mm)metalscrews
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”(12mm)screws.Iftheoffset
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 27 and
29).
3.Use another elbow to turn the chimney
vertically. Secure the elbow, using three
(3)1/2”(12mm)screws(providedwiththe
elbow).
4.Useaplumb-bobtolineupthecenterof
the hole. Cut a hole for the chimney in the
ceiling/oor.Framethisholeasdescribed
previously (refer to section Chimney Instal-
lation Instructions).
5. From below, install a firestop (See Figure
22a).
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.Tolockitinplace,turn1/8ofa
turn. Fasten the straps attached to the elbow
to the surrounding frame, using nails or
drywall screws (see 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.Useaplumb-bobtolineupthecenterofthe
hole. Cut a hole for the chimney in the ceiling.
Frame this hole as described previously.
5. From below, install a firestop (see Figure
22c).
6. Continue with the regular installation.
Note: When using AC chimney, an AC6SB
starter section must be used before install-
ing an elbow. When an offset is needed
immediately off the top of the fireplace, an
elbow starter section, AC6SB30 (H3780), is
available.
