F. Equivalent Feet of Pipe
The table below can help you calculate the equivalent feet
of pipe which is a method used to determine pellet vent size.

G. Pipe Selection Chart
The chart will help you in determining proper venting size
according to the equivalent feet of pipe calculated previously
and the altitude above sea level of this installation.
Figure 14.2
a. Locate the calculated equivalent feet of pipe on the vertical
left side of the chart.
b. Move to the right horizontally on the chart until you reach
your altitude above sea level.
c. If you fall below the diagonal line, 3 or 4 inch (76 to
102mm) pipe may be used.
d. If it is anywhere above the diagonal line, a 4 inch (102mm)
diameter pipe is required.
NOTICE:
• A 90° elbow is 5 times as restrictive to the fl ow of exhaust
gases under positive pressure as 1 foot (305mm) of hori-
zontal pipe.
• A foot of horizontal pipe is twice as restrictive as a foot of
vertical pipe.
WARNING

Example 1: If the equivalent length of pipe is 23 feet (7m) with
altitude of 8,000 feet (2438m) you must use 4 inch (102mm)
diameter type "L" or "PL" vent.
Example 2: If the equivalent length of pipe is 12 feet (3.7m)
with altitude of 6,000 feet (1829m) you may use 3 or 4 inch
(76 to 102mm) diameter type "L" or "PL" vent.
