C. 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.

D. Pipe Selection Chart
The chart will help you in determing proper vent-
ing size according to the equivalent feet of pipe
calcuated above and the altitude above sea level
of this installation. Figure 13.2.
Locate the calculated equivalent feet of pipe on
the vertical left side of the chart. Move to the
right horizontally on the chart until you reach your
altitude above sea level.
If you fall below the diagonal line, 3 or 4 inch (76
to 102mm) pipe may be used. If it is anywhere
above the diagonal line, a 4 inch (102mm) diam-
eter pipe is required.
The chart reveals that a 90° elbow is 5 times as
restrictive to the flow of exhaust gases under posi-
tive pressure as 1 foot of horizontal pipe, and a
foot of horizontal pipe is twice as restrictive as a
foot of vertical pipe.

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