I bought this boilers a few years ago, paid $400, when the furnace in my house broke because I forgot to bleed the air before firing. We later decided to go with forced air so we can have AC. I started to install and started to put the electronic ignition off my Kenmore that broke onto it. Thus the manual gas valve and pilot sitting next to it. The parts, some new, some used, are left over stuff from my Kenmore(Sears) that broke. This unit was working good when I bought it. I never used it. If contacting me, text is best, but feel free to call. (419) 376-95sixty-two. Please leave a message if I don't answer. Thanks, Matt.
