May 26, 2017 · Nickfromwales. The condensing boilers need a continuous uphill rise, from boiler to flue terminal end, so that the condensed water runs back down the flue to the boiler and out the condensate drain. The idea is that no water pools or sits anywhere in the flue run, and also none drips out of the end of a normal horizontal flue terminal.
