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 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. These elbows can be installed in either
the vertical or horizontal run.
Note:
On vertical venting the first elbow does not get counted.
Note:
LP and Nat gas models can be top vented.
Acceptable vertical and horizontal vent run.
(40' maximum vertical and 20' maximum horizontal)
Unacceptable vertical and horizontal vent run.
