OK the L4006A was what I was referring to as the high limit... I just saw the #'s 4006 on the Honeywell box. It is at 200. I turned it down to 180 previously about a month ago in an effort to be more efficient, the next day I noticed the fire was out. I'm not certain if it went out for that reason or some other but I re-lit and turned it back to 200 which is where the dealer set it upon installation.
Something else about that L4006A, the electric company replaced the transformer (at the pole)one day and when they did I had to trip the breakers for the oil & coal boilers to start running again(3-4 hours later). I also had to press the reset on the L4006A for it(the fan or pump?) to start up again. I'm assuming cause we had no power for a while that the coal was still lit and water was not being circulated and got to 200+ and tripped it out.
Like I said I don't know much about these boilers but I do want to learn which is part of the reason for joining this forum. Thanks for all the input, everyone has been so helpful. Some forums out there which will remain unnamed are full of grown ups who act like they are in middle school. I appreciate it
