Some updates on the RUSH No. 9 I have redone some gaskets mostly on the lower side doors and front bottom of the pit door. These have helped in elininating leaks that allowed fresh air to enter and go up the flue. Now the air comes up though the grate and thus the fire. Burns much better!!
I have found I also was shaking too much, now maybe a shake after several hours of burn. Still learning as I occasionally let it get too low and loose draft and die. The gasketts are a help. Also went to larger coal using Nut and Stove. Once I have a good fire I load the bin all the way and let it burn.. We still need to place ceramic tiles on the walls, you acn see two samples of some wood looking ceramics we like.
Having fun staying warm on this snowwy day 29degrees outside. Hope to keep learning as I go.
