Well, she's up and providing heat to house and DHW. I ran into a bit of a hiccup though, it was my own fault. After about an hour or so of getting the water up to temp, I had been keeping close tabs of how she has been operating. I could hear one of the solenoids making a loud buzzing noise so I open the back panel where they are located, tap the offending solenoid and then attempted to close the panel door. Well, there are 2 locking tabs that hold the door close. When I tried to pull and turn them, they both broke. I had no way of keeping that door closed. So, to the basement of the house I go looking for a solution. I found some self tapping screws and installed them. I went inside to have lunch and when I came outside the digital display was showing "HI" (I doubt that it was a greeting), meaning that water had reached over 200 degrees and she shut herself down. So, to the rear panel I go looking for the problem. I found it immediately; when the tabs broke that holds the rear panel door closed, it left 2 holes that neglected to seal shut. To the basement of the house where I found my silicon sealant and filled them in. Problem solved and she been running like a charm. I hope she keeps it up throughout the winter. Roger
