To Use the Vent Graph (Figure 22)
1. Determine the height of the center of the horizontal
vent pipe. Using this dimension on the Sidewall Vent
Graph, locate the point it intersects 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 unit
in accordance with same.
EXAMPLE A: (Top Vent Connections with Vertical
Termination).
not exceed 6.5 feet.
EXAMPLE B: (Top Vent Connections with Vertical
Termination)
not exceed 14.5 feet.
SPECIAL NOTE: For each 45 degree elbow installed
in the horizontal run, the length of the horizontal run
MUST be reduced by 18" (45cm). This does not apply
if the 45 degree elbows are installed on the vertical part
of the vent system. Reduce 3' for every 90° elbow.
Example: According to the chart the maximum
horizontal vent length is 20' and if two 45 degree
elbows are required in the horizontal vent it must be
reduced to 17'.
The maximum number of 45 degree elbows permitted
per side wall installation is two (2). These elbows can
be installed in either the vertical or horizontal run.
Note: On vertical venting the first elbow is not
counted.
