Chimneys
1.
Install the first elbow; turn it in the required direction. Fasten it to the chimney with the
three (3) _" (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) _" (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 34 & 35).
3.
Use another elbow to turn the chimney vertically. Secure the elbow, using three (3) _" (12
mm) screws (provided with the elbow).
4.
Use a plumb bob to line up the centre of the hole. Cut a hole for the chimney in the
ceiling/floor. Frame this hole as described previously (refer to section 4.2).
5.
From below, install a firestop (See figure 28).
6.
A support (XST+ or XSO+) must be used on the first 15’ section (5 m.).
7.
Continue with the regular installation.
ACBI 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 33).
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 centre 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 29).
6.
Continue with the regular installation.
