C. Venting & Use of Elbows continued
Note: When the amount of vertical pellet vent pipe in the system exceeds 15 feet, 4” pellet vent pipe should be used.
Note: Equivalent Venting Length decreases as altitude increases.
Note:WhentheHighAltitudeFanBladeisused,themaximumlengthofOutsideAirPipedecreasesto20ft.
Example:
A unit with an EVL of 13, is to be installed at an altitude
of 3,000 feet above sea level.
From the chart to the left, at 3,000 feet of altitude, the
maximum permissible equivalent venting length is 26
feet. Therefore this would be an acceptable installation
with no need to change the combustion blower fan.
However, if the same unit (EVL 13)was to be installed
an altitude of 9,000 feet above sea level, the installation
would no longer be acceptable and the equivalent vent
length of the pipe would have to be reduced for proper
unit operation.
