The table below can help you calculate the equivalent feet
of pipe which is a method used to determine pellet vent
size
(Figure 16.1)

• 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.
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 16.2)
.
1. Locate the calculated equivalent feet of pipe on the
vertical left side of the chart.
2. Move to the right horizontally on the chart until you
reach your altitude above sea level.
3. If you fall below the diagonal line, 3 or 4 inch (76 to
102mm) pipe may be used.
4. If it is anywhere above the diagonal line, a 4 inch
(102mm) diameter pipe is required.

Vent surfaces get HOT, can cause burns
if touched. Non-combustible shielding or
guards may be required.

NOTICE:
A 90° elbow is 5 times as restrictive to the flow
of exhaust gases under positive pressure as
1 foot (305mm) of horizontal pipe. A foot of
horizontal pipe is twice as restrictive as a foot
of vertical pipe.
