I'm in the third year of my Harman P68, and enjoy the thing. Good heat, and I haven't run the furnace at all in three years. But, the warranty end this year. And, in the middle of Winter it's hard to get support when the temp is -10 and 3 AM ! What to stock for a spare part kit ? Control board, ESP probe, burnpot cast iron cover, distribution blower ? Since the stove is paid for, I was planning on making a spare part kit as part of the capital cost for heating in 2008. Any suggestions ?
