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" (457 mm). 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. These elbows can be
installed in either the vertical or horizontal run.
Acceptable vertical and horizontal vent run.
Unacceptable vertical and horizontal vent run.
Note: When rear venting unit, adjust air shutter from 1/16" open up
to between 1/8" and 3/16" for NAT gas.
Adjust air shutter from 1/4" open to between 5/16" and 3/8" for
Propane Gas.

NOTICE:
When rear venting unit, adjust air shutter
from 1/16" open up to between 1/8" and 3/16" for
NAT gas.
Adjust air shutter from 1/4" open to between 5/16"
and to 3/8" for Propane Gas.
