Hi David, and Happy New Year! Damp Chaser supplies three ring spiral note books with installation charts and suggestions to technicians who have installed enough systems to be counted as one of their instllation experts. Most of the diagrams are supplied by technicias who feel they have been successful and are willing to pass along their experiences. Presumably Damp Chaser agrees. On some diagrams, Damp Chaser makes suggestions of their own. You may wish to get one for yourself. Probably if you called them they would supply you with one. Personally I don't agree with all that I see in the book, but the diagrams are still a good starting point, and may even help convince a customer. And yes, I agree with your obwervations on the Steinway B installation. Ed Hilbert Vermont Chapter
