I have coal/ oil 520 efm . Dryer was taking air from boiler shutting down oil gun. I want to run all coal . I just started coal fire, hope it stays alive high set at 200 low at 160 (10 diff ) nobody home durning day .I hope it dosen't temp up to 200 shutting down timer this is all knew to me hope I did the right thing, going back to coal like my parents had. Thanks for all your help on here
Your draft and Type of coal will determine where the air will be set not all coal is the same some need more air to burn completely others will need less air to burn completely watch the draft and coal that will tell you what settings will work
for your set up you may need more air to burn the coal completely or you may need less air all depends on coal your using
and how well your chimney drafts .
My winter setting is 170 low 200 high 10 diff timer 1.5 minutes every hr. feed rate 3 to 4 depending on outside temp
air setting 5 to 6 depending what feed rate I am using I burn buckwheat # 1 size coal it needs higher air to burn
completely being it is larger then rice coal but it feeds less coal per hr so I use less coal then using rice also buck is much cleaner and always available the price does not fluctuate like with rice does in winter time at most breakers.
