The maximum allowable equivalent length of flue pipe from the appliance to the power venter is 100 feet. Several factors must be considered when determining this length, including the size of the power venter, the diameter of the flue pipe, and the capacity of the appliance (measured in Btu or GPH). The installation instructions provide a unit sizing chart and detailed guidance on calculating the total equivalent length of flue pipe.
