To Use the Vent Graph
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:
If the vertical dimension from the floor of the unit is 12 feet,
4 inches the horizontal run to the outer wall flange must not
exceed 12 feet, 3 inches.
EXAMPLE B:
If the vertical dimension from the floor of the unit is 6 feet, 9
inches, the horizontal run to the outer wall flange must not
exceed 6 feet, 6 inches.
SPECIAL NOTE: For each 45 degree elbow installed in the
horizontal run, the length of the horizontal run MUST be
reduced by 18 inches (457 mm). This does not apply if the
45 degree elbows are installed on the vertical part of the vent
system. Reduce three feet for every 90° elbow.
Example:
According to the chart the maximum horizontal vent
length is 20 feet and if two 45 degree elbows are required in the
horizontal vent it must be reduced to 17 feet.
The maximum number of 45 degree elbows permitted per side
wall installation is two. These elbows can be installed in either
the vertical or horizontal run.
