Good day, folks, I bought an old used kiln, Gare Kiln 2541 A. I am not sure of one of the controls. Unable to find any manuals for the kiln online.  Any useful info would be much appreciated. Thank you. Regards, Kanna Das Canberra, Australia Images attached. Gare Kiln, Gare Inc,  Haverhill, Mass 01830 Model 2541 A serial 10.42.88 --end of message --------
