Improper installation, adjustment, alteration, service or
maintenance can cause injury or property damage. Refer
to the owner’s information manual provided with this appli-
ance. For assistance or additional information consult a
qualifi ed installer, service agency or your dealer.
WARNING
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 12.2.
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 fl ow of exhaust gases under
positive pressure as 1 foot of horizontal pipe, and
a foot of horizontal pipe is twice as restrictive as
a foot of vertical pipe.
D. Pipe Selection Chart
The table below can help you calculate the equivalent feet
of pipe which is a method used to determine pellet vent size.

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
Fire Risk.
• Only LISTED venting components may be
used.
• NO OTHER vent components may be used.
Substitute or damaged vent components may
impair safe operation.
