TWIST LOCK PIPES
When using twist lock pipe it is not necessary to use seal-
ant on the joints.
To join twist lock pipes together, simply align the beads of
the male end with the grooves of the female end, twisting
the pipe until the flange on the female end contacts exter-
nal flange on the male end. It is recommended that you
secure the joints with three (3) sheet metal screws, how-
ever, this is not mandatory with twist lock pipe.
Figure 13
NOTE: Sealant is not required to assemble fireplace
venting. Do not use silicone sealant at the inner flue
exhaust connections.
To make it easier to assembly the joints, we suggest put-
ting 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 14
, 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 81/2’ (2.6 m).
