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 the three (3) 1/2” (12 mm) metal screws provided with the elbow.

2.Install the necessary chimney lengths to achievetherequiredoffset. Lockthechimney 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 30 and 31).

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 section Chimney Instal- lation Instructions).

5.From below, install a firestop (See Figure 24a).

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 (see Figure 29).

2.Install the necessary chimney lengths to achievetherequiredoffset. Lockthechimney 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 24b).

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 immediately off the top of the fireplace, an elbow starter section (AC6SB30) is available.
