The Harman is very tight and proper operation of the bottom damper is all that was needed. The top dampers are primarily there for wood burning.

It's funny how I was mildly critiqued and ignored when I stated my findings. It seemed at the time everyone and I mean everyone was so sure I was wrong and a barometric damper was 100% necessary. I was the Inventer of "foil your baro" statement for more positive results for the newbie. And I was criticized by senior members. I feel better now to know I wasn't incorrect in my understanding of efficient use of my equipment. Feels good to be in company of non-believers. But I am not hearing any of them now. John, where have you gone?
great post ! stove shops make $ sell gaskets, sealer, baros, mpd's, pipes, chimneys, caps, tmeters, adapters, paint etc. might not sell everyone stove but little things put $ in drawer. "non-believers" = less money in drawer, you get lip from sellers. thats one reason.
2nd reason "believers" spend $ on stuff not needed, don't wanna admit taken hook line sinker, you get ignored.
3rd reason most old iron leaks air like sieves & not designed airtight, baro & mpd on leaky overdraft overfiring stove, band aid on cancer. instead fix leaks first. old stoves look great, if leaky cracked rusty, not much of a stove. owners get defensive, leaky stove needs extra gadgets to run. pride & ego ? me if it heats on bucket a day, no CO in house, no big repairs, thats good stove. I want stove that heats with one knob, not project.

I'm happy you guys are confident your appliances run just fine without any flue dampers. I don't think one is necessary on a unit with an automatic primer air control, but it may run even better if one is used. Especially a barometric. There are many advantages to keeping a steady, consistent draft pressure.. :)
