Dealer ran out of the nice, clean Okanagans we were burning and gave us a ton of Cleanfires instead. He claims the Cleanfires are just Okanagans under a new name, but they are behaving like a completely different brand. I am getting such an ash buildup that I have to clean after every bag and a half, instead of going several days between cleanings. The real problem is that there is gunk building up on the door glass that is very hard to clean off. I'm wondering if it's creosote, by any chance, and if so, how to prevent it. It is a yellow film with a fairly hard finish that will not come off with a vacuumning, and which requires a lot of rubbing with the isopropanol-based glass cleaner I have (Glass Cleaner by Stove Bright, "removes creosote deposits and soot"). Scraping with a single-edged razor blade does a fairly good job, however, thanks be to God. So the question is how to tweak the flame. It needs to be hotter, in any case, since these pellets don't put out the same level of heat, "Okanagans under another name" or not. (If they really are the same, then the first two tons must have been from last year's cutting; the difference is night and day.) But to get a hotter flame, do I give it more air, or more pellets?
