One of the newer technologies I'm really excited about is a Fernox filter, Figure 3, and the water treatments involved. Using an ECM based circulator the protection of the water is essential for proper operation and a long life and the Fernox and chemical treatments are essential to that goal. I'm going to start telling you more about this project with the filter first, because it was not only part of the new system but also part of the old one. As I said, over the coming months we'll talk more about this and the updates. Just a few days before the scheduled rip-out, I treated the system with Fernox Cleaner F5 Express and let the system run. The day before the rip-out the system was drained and flushed. As the system emptied and was vented for the last time the water ran black with the dirt those 25 years had produced. I can tell you that the filter and chemicals work because we are already feeling better output from the 25-year-old copper finned-tube baseboard all through the house. When the job was done we added the Protector F1 Express, and now we wait. We have flushed the filter a few times, and every time we do we are still seeing some black residue. Hopefully that will go away. I was really impressed with the kit provided by Fernox USA. This is a well thought out plan that includes even the proper fitting and adapter to place the charged cans of cleaner and protector onto the system boiler drain to be introduced quickly and easily. In upcoming articles I'll let you know how we're doing, what we're finding and will continue to thank those involved. But for now; many thanks to Adam Dubin, Bob Flanagan, Jim Harding and lots of other great people at Slant/Fin for the boiler technology. Many thanks to Bob Mercer and the folks at Weil-Mclain for your assistance on the indirect. Many thanks to Mark Chaffee, John Barba and the crew at Taco for lots of specialties and controls. Many thanks to Mark Nelson and Jim D'Anthony for ongoing assistance with Riello burners. Many thanks go to my education partner Jim Todd and others at the Beckett Corporation for assistance with planning the control theories yet to come. A special shout of thanks to Bruce Marshall and others at Emerson-Swan, Fernox and Flexcon for suggesting new tech- nologies and to Bruce for acting as a well-used sounding board and idea generator — thanks Bruski! Last but not least, a big thank you to Andy Renzoni and his crew from Future Piping for a fantastic installation that should last for the ages, Figure 4. I'll be writing a lot more about this job down the road and give you my observa- tions and findings as they develop.
