Twist Lock Pipes
When using twist 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 silicone sealant are the sliding joints of any telescopic vent section used in the system.
To join twist lock pipes together, simply align the beads of the male end with the grooves of the fe- male end, twisting the pipe until the flange on the female end contacts external flange on the male end. It is recommended that you secure the joints with three (3) sheet metal screws, however, this is not mandatory with twist lock pipe. Figure 14
To make it easier to assembly the joints, we suggest putting a lubricant (Vaseline or similar) on the male end of the twist lock pipe prior to assembly.

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 15, 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 6’ (1.8 m).
