Chapter 2. Installing Pipe Nozzles
2.4 Determining and Marking the Second Nozzle Location (cont.)
4. Wrap the strip of film around the pipe with one edge running along the vertical scribe line at the first nozzle
location. Make sure the strip overlaps squarely around the pipe and mark the overlap position of the strip. This
equals the circumference of the pipe.
5. Remove the strip of film and fold it as shown below to determine the position which is diametrically opposite the
overlap position when the film is reapplied to the pipe.
6. Mark the outside of the fold for reference.
