Final Say appears to be a Cover Our Asses statement from the legal department, the same folks who mandated the "Caution! Hot while in use!" sticker on my stove.

Did not know that Harman had the final say since they are unable to correct the flaws and archaisms in their own stoves.

I have contemplated a mpd on my Harman. With the baro wide open I can still toss in a small piece of tissue paper in the fire and just as it lights off its pulled up and out like a vacuum cleaner is pulled on the thing. I do believe the setup of chimney and drafting ability play a major factor on choices that should be made. But to say anyone would be fool to use one of these devices is an ass statement. Just my .02$

Well unfortunately there are people in the world that do need these cautions, they're the same type that need Goveco telling them how to live.

Ya know Bruce, yer right. It seems in the world today people are getting drummer sometimes. Why else would we need a warning not to stick our fingers in the rotating belts of an engine.
Our society is being molded into being dummies. Don't touch the electric fence or use a hair dryer in the bath tub.

Just one persons opinion and that's fine. When I was 10 a black cat crossed my path while I was running under a ladder holding a pair of scissors with my Chuck Connors All Stars untied. And just before that I found a Playboy magazine and I was alone for awhile. Guess what? The cat is dead and I can still see! :o and my mpd's work fine! Thanks for the warning Mom! :lol:
On a serious note, I believe in the collective experience of hundreds if not thousands of folks with the same goal in mind. Peace out man!

baro dampers on coal stoves- never
manual dampers on coal stoves- only on non-airtight stoves, not needed on new stoves

per below site, good information, go to link and scroll to BOTTOM for damper info
they use both Harman and Hitzer stoves

http://www.videointerchange.com/coal_stoves.shtml

The following links make for interesting reading. However, beware that like any other forums, some of the opinions are posted by those with little or even no experience or understanding about why coal stoves behave the way they do, purpose of dampers, use of barometric dampers etc etc etc... In contrast, there is much valuable info from those that have years or literally generations of practical "hand me down" experience in the operation/maintenance/installation of wood or coal stoves. As with any open forum, you will be forced to sift thru it to separate out the truth based on the physics involved, from personal opinions, rumors and just plain good old fashioned BS from those proclaiming to be "experts" without themselves ever having owned or even experienced a coal stove in operation ! There are more of those than you might ever first suspect !

I actually had an email discussion with the person that owns that site, I came across his coal page because I have an interest in video restoration.

His concern about the baro's and one I had not thought of is many people in the Northeast use wood especially in his area and they have a lot of chimney fires. You never use a baro with wood becsue it provides an ideal source of oxygen if you have a chimney fire. His major concern was people switching to coal and if they don't clean the chimney now have a situation where it can get out of control if for some reason you get a chimney fire. Setting aside the baro issue the bigger concern with the creosote is it will dry out and flake off when using coal and can come off in large chunks. This can potentially block the flue pipe, he probably would have been better off advising to clean out the chimney in the first place.

My experience with MDP's so far.... closing it cools cools er' down and opening heats er' up. Check damper door open on windy days and closed on the calm.
