This may be a bit far off topic for this forum, if it is I suppose that the powers that be can deep 6 it. I am in the intial phases of developing a white paper, { for intra-company use only }, on positive pressure, vacuum and differential pressure/proving switches for gas fired equipment. Troubleshooting techiniques, technical and complex internal drawings, specific application design, { ie., boilers, high efficiency and two stage differentials }. Any input including subject information sources for research, personal techniques, test instrumentation, home brew instrumentation and if possible drawings of any apparatus modifications available. If you have any of the requested information, and would prefer responding to this request outside this forum, please feel free to reply to tberlin@bluemarble.net Thanks in advance for any input that you can provide. Respectfully.:)
