To Use the Vent Graph

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.

From the point of this intersection, draw a vertical line to the

bottom of the graph.

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 NOTICE: For each 45-degree elbow installed in

the horizontal run, the length of the horizontal run MUST be

reduced by 18 inches (457 millimeters). This does not apply if

the 45-degree elbows are installed on the vertical part of the

vent system. Reduce 3 feet for every 90-degree 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.

NOTICE: Do not count the first elbow on vertical venting.
