I know this is a crappy pic but wanted to show how this stove is running with 2 ft. off the top of stove to a 90 degree elbow then 3ft out horizontal to the tee and then 6 ft. vertical....and it is 36 degrees warm out....No smoke back or back puffing....I usually have a 3ft taller chimney but because of mishap it will run this way till warmer weather....
Many folks are surprised at how well you can run a stove with a short chimney. Still better to be up around 15' if possible, but, sometimes you just do things different and it works.
Glad you could get it back to burnin Milleo.....would really suck to have to use your alternative heat the rest of the winter, besides the cost you just can't get warm any other way after burning wood.
