Installation

TEE CAP (TC)
1. Use to block one of the openings of horizontal or vertical tee.
2. Removable, it facilitates access for inspection and maintenance of
the chimney.
3. The installation is the same as for lengths.
4. When removed, the old silicone must be cleaned out and a new bed
of sealant must be applied.
DRAIN-TEE CAP (DTC)
1. Use as a drain for vertical stack.
2. Connect to a suitable drain fitting to allow rain entering the chimney
to wash down, dilute and remove any corrosive residue.
3. Same installation as a tee cap.

INCREASER, STEP OR TAPERED
1. Use to increase the diameter of the chimney flue.
2. The tapered increaser induce less pressure drop than the step in-
creaser, but requires more space. It has a 15° side angle and provides
increases of one, two or three size. The height of the fitting varies
depending on the diameters to be increased (see figure 17).
3. The tapered increaser have the same load strength as a standard
length, but the step increaser is a non-structural part and must be
protected from axial and lateral load.

ELBOWS
1. Elbows are used for changes in direction in horizontal or vertical
portions of a chimney system.
2. All elbows feature the standard joint assembly as described in Section
A - Chimney and Fitting Assembly.
3. Elbows are used in combination to make different angles ranging
from 3° to 90° in horizontal and vertical breechings of the chimney
system.
4. Elbows are not designed to take bending loads and must be structurally
supported (see figure 17). Structural parts such as posts or beams
may also be needed to hold chimney supports in position.
