          Comments about Adjustable Vent Length:

          This is a great length of pipe. I have a field stone foundation wall that does not allow me to get one standard length without shimming the mounting board. This allowed for a little more flexibility. This will be my second install of a Rheem, 3rd tankless unit.

              Comments about Adjustable Vent Length:

              The vent came with just 2 pieces, the inside and the outside part but they did not work together until my plumber used an adapter piece that I had mis-ordered from another firm. I think there should have been some kind of instructions for this thing, maybe all the required pieces were not shipped, or the rheem person working the help line did not give me the information that it needed an adapter.


              great deal

              • Adjustable Vent Length


                would like to know if the adjustable vent length of 3-5in vent pipe is supposed to have the inner 3" piece along with it. Because my order did not have one included.
