I use whatever my stove mfg. tells me to................
I have a VC Vigilant 1 with the coal conversion kit installed. From what I have read either Pea or Chestnut can be used by setting the hopper/magazine throat accordingly. There is also two other settings but no info on what size that would be, maybe stove?
I have been using pea, going about 12+ hrs. on a full hopper, stove running at an average 400*- 425* measured at the suggested spot (from what I read on another thread).
So since instructions have either pea or nut and I try nut, from what I am reading above am I correct to understand that the stove will run hotter, but the run time shorter, as in my case shorter than 12 hrs.?
Also one other thing I am wondering is how much higher than what I am running now would be overheating? Did run it for a bit at 450* though but I set it down a little thinking I could conserver some coal.
