To Use the Vent Graph (Figure 19)

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 35 feet,

the horizontal run to the outer wall flange must not exceed

6.5 feet.

EXAMPLE B:

If the vertical dimension from the floor of the unit is 6.5 feet,

the horizontal run to the outer wall flange must 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 does not get

counted.
