t-LoCK PIPeS
When using unitized T-Lock pipe it is not necessary to
use sealant on the joints. The only areas of the venting
system that need to be sealed with high temperature sili-
cone sealant are the sliding joints of any telescope vent
sections used in the system.
To join T-Lock pipes together, simply align both inner and
outer pipes with the next section. Align the internal beads
of the female end with the T-channels of the male end.

how to uSe the VeNt GraPh

The Vent Graph should be read in conjunction with the
following vent installation instructions to determine the re-
lationship between the vertical and horizontal dimensions
of the vent system.
1. Determine the height of the center of the horizontal
vent pipe exiting through the outer wall. Using this di-
mension on the Sidewall Vent Graph, Figure 10, locate
the point intersecting with the slanted graph line.
2. From the point of this intersection, draw a vertical line
to the bottom of the graph.
3. Select the indicated dimension, and position the fire-
place in accordance with same.
exaMPLe a:
If the vertical dimension from the floor of the unit is 11' (3.4
m) the horizontal run to the face of the outer wall must not
exceed 14' (4.3 m).
exaMPLe B:
If the vertical dimension from the floor of the unit is 7' (2.1
m), the horizontal run to the face of the outer wall must not
exceed 7' (2.1 m).
