I've seen posts other places on the site that says .02-.04 is a good range for an EFM (correct me if I'm wrong). The only thing I wasn't sure is where this was measured. At the damper, at the hole in the door...over the fire itself? Any advice would be greatly appreciated. After the 2nd summer of fighting some outfires which I can only attribute the draft....(feed, aquastat, air, timer, etc.) settings work perfect 99% of the time and my flue is clean of fly ash. Just sometimes when the weather goes crazy....change in temp, pressure, humidity...I lose the fire. I'm hopeful that the baro will help this as well as help during winter heating.
Thanks in advance for the advice. In a week or two I plan on cutting up my system and make some upgrades to the original half-@$$ design such as air eliminators, isolation valves, etc so you might see me on here a lot!

Do the numbers matter or do I adjust it to whatever it takes to get .02 though the door while the fire is running? Or should that be set to .04/.05 to get that in the pipe and that in turn should be getting me close to .02 over the fire.
