Venting Graph (Dimensions in Feet)
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" (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:
Only natural gas models can be rear vented.
