Found a Harman P61 on Kijiji, guy said it had some issues, went and picked it up yesterday...what a find! Fuse in the board was blown, replaced it and all the lights came on and ran fine in test mode. It was full of creosote, so must’ve ran low for a longtime was what I was thinking...Fired it up and the flame was a bit lazy...lots of smoke, and I could hear a whistle...checked the air intake and the flapper was jammed closed, once opened it ran like it should. It came with all piping except appliance Adaptor, I think that was one of the other problems as well. Also one of those novel powered by heat fans.
