Another baro question

PostBy: joeq On: Sat Jan 18, 2014 5:44 pm

Today, I made a trip to a local Fireplace store, and the counter clerk was very "chatty". I originally was asking about Hot Ash vacs, and told him I burned coal, and his 1st reaction was :shock: ( kidding tho,) cause he told me yrs ago he had a Chubby and loved it. He was a middle age guy, and "supposibly" has been in the business awhile.
When I mention my baro installation, and performance observations, he told me my damper door weight should be adjusted so the door is in the closed position always, "except" when the wind blows. I told him Surdiac recommended an -.04 draft, and if my door was closed most of the time, my draft is up around -.06-07. He said it shouldn't make that much of a difference. But I know my burns times drop a few hrs when my draft is that high. I agree my stove temp will run higher with a higher draft, but don't want to sacrifice what little burn benefits I'm receiving at this setting. I've experimented with my MPD positions, and whether it's totally closed, or fully open, the baro door doesn't adjust much at all. Any opinions are welcome. Thanx. Below is a pic of where my damper door is usually situated.

Sounds to me like you should take the clerks advise for chewing gum and not coal burning. you have the tools and the experience with your stove. Chewing gum!

Your baro position looks like mine in order to keep my draft at .04 whenever the temp is below freezing. Mine will close up if the temp outside gets into the 40's or will open much wider if its cold and the wind blows maintaining the .04 reading. Since the baro behavior will be different for each installation, hecan't make a blanket statement like he did.

I agree. To me, it doesn't look too severe.

Joeq,I have tried different baro setting from .04 to .08 but I have settled on .07 or .08,my stove runs good at that range plus if it was set at .04 it would always be opened(I have never had lower then .05 except when the baro stuck opened and it went down to .03)the baro will keep the stove at a consent temp wind or not.Keep trying different things until you get it but I can pretty much bet your best info will come from NEPA Crossroads :D and also remember that every house is different and set up is not the same so do what works best for you ;) .

thanx opti-man. I've had my draft around -.06-07 and the stove also runs good. just won't go all night at that setting. I haven't been able to figure out, how to have my cake and eat it too. (I know, replies from all the stokers and round stove guys will chime in. ) :)
