I just bought a 25-pdvc used from a guy on craigslist to heat my 24x40 insulated section of my new pole barn. I have r-19 in walls and about 11-13 inches of blown in cellulose in ceiling. The settings for bottom 3 buttons are 452. Is this what I need to keep it at? Stove seems to be burning nice. But want to make sure this is set at optimum settings. I also read in other forums about a b c d modes. I'm lost about all these settings. Any help would be appreciated. Also. When I put stove of 9 9 settings to get it cranking out heat she heats up so much top of stove and sides get pretty damn hot. Is this ok? Also the blower blows out hot heat but on the 9 setting I'm not really impressed with how much hot heat comes out. How much should blower be blowing out?
