...and as you sit comfortably for many years warmed by that boiler thinking of the thousands of dollars saved.....I'll bet a couple small glitches during installation will be long forgotten.
If it is made by human beings, there is a chance for an error, and the electrical schematic from the factory could use a 'user friendly update'. I didn't read all the posts, but did you remove an 'old beast' and go with the combo K-6? Nice small footprint.....quiet boiler.
Have a couple friends come by and show them the boiler in operation. They will say: it isn't running, but it is very warm.......not much happens to be that efficient. Not even a clink, gear sound, auger tube rattle or crunch......it is like magic. KISS works well for many of the coal fired units, hand or stoker fed!. Enjoy! Get you coal on order TODAY!!! We used Buck size, and have for years. Do not think that Rice is your only option.
