PART 7 What the hell happened? Well, it's PrecisionChem's position that an overfiring situation occurred, creating excessive steam, in the presence of a biological. They are right. There was an overfiring, I posted pics of it on here last year. Search this forum with "eeeasy big fella". They also said that a piece of hen manure the size of a quarter or a teaspoonful of 5-10-10 garden fertilizer would be bad news for a Garn 2000 or any open system ESPECIALLY if it boiled. They said biological contaminates can get into open systems just from dust in the air. Mike said he hates to use the word "hospital" in trying to emphasize required sanitation for open systems but it can be almost that critical. So, since no other Garn owners have experienced this I guess it was just a fluke. But since it did happen I just wanted to point out what I did wrong and what to watch out for: Don't over-fired, look in manway often to check water level and keep full as possible using filtered water and take sample from manway not piping if you see any discoloration and do a test. Mike and the folks at PrecisionChem were very helpful and accessible all the way. Phone calls, emails, listening to me holler and bit-ch, you name it, they're great. Chris Holley is my Garn dealer and he is a good guy too. Very accessible, I always get a phone call every time I email him. He felt bad because he had been telling guys that after you overfire your garn a few times you'll get the hang of it. Didn't think it was a big deal. He also felt confident that the testing program would prevent any corrosion issues from getting out of control. I emailed him all my pics and he forwarded them to Martin Lunde. I told Chris that Dectra ought to at least help me out with the cost of the water treatment chemicals and he said that was unlikely to happen and offered to contribute something out of his pocket. I declined. He and Martin and Mike were all in the loop and when Martin heard that it was Mike's position that overfiring was the issue, he simply said that it says in the manual to not operate above 190. I guess it probably does, somewhere.
