I purchased an Alaska Model 140 coal stove last year and didn't get the heat out of it that I expected. I spoke to someone today and he said I didn't have it installed properly. There is a metal box with a metal tube sticking out of it that I never installed because I couldn't figure out where it went. I am told that this is my problem. Can anyone help me out and tell me what this does and where it is installed on my stove.
Thanks
