I will have your answer in one moment
Expert:  Machinc replied 2 years ago.
Your maximum run is 50 meters. 164 feet
Your rise is 30 meters or 98 feet
The foot measurements are rounded off to the
Nearest foot measurenent on the short side.
Bear in mind a unit fifty feet across a building
will require more than a fifty foot run .
Figure the distance usung a scale drawing
allowing about a ten percent error. Or
Measure the actual building using a tape
and keep track of bends and turns and the height
up the wall to the unit. This is for the run .
Simply put the run( 164 feet) has to terminate no higher than
98 feet above the unit( this is the rise) . There nay be special applications made For installation in high-rise apartment buildings such as placibg the unit on an intermediate floor but
This is no problem to achieve in home use .
I will be glad to answer any questions you may have

Bear in mind that the rise cannot be run vertically for the full length and
different size pipe affects the unit .
An error here can damage the unit.
It is best to have this part of the installation
professionally done as calculations are needed that are usually
beyond the scope of the average" do it yourselfer".
