OK so I need the big guns here . Over the past weekend and during xmas Jotul 550 was working very well. The last two days I have had terrible performance. Fire builds slowly, poor secondary burn with short burn times. need to leave primary open more than usual. Stove temp does not reach high temps easily. What changed; 1) I used some creosoot spray for the first time this year a couple days ago. 2) Yesterday I lifted the skamole baffles up and used my hand to feel around for ash and junk while I was sweeping out the ash. Could I have somehow blocked secondary air intake? The manual does not show the intake. During my sweep out I lifted the baffles to inspect the flue which looks fine. From the ground I don't see any blackening at the cap suggesting creosote and I'd be surprised if I had a significant issue. Only used the cresoot spray and felt around for crud above the baffles as a precaution. Any ideas? Going to let it cool and remove the burn tubes baffles and baffle plate later.
