You mean the stick match I use to see if my chimney draws?? My MPD stays open 99% of the time. Go with the mano. WW. To many good reports on them. I'm just old & grumpy! . Yes I would say 03-05 is a good reading.

I called DS and they said a .06-.08 is a good draft . With these warm temps I was hovering in the .08 area. They said if I can't keep my fire low enough to install a damper , either style is fine with wood or coal . But the manual is how most people go because of the $$.

Was that with the stove damper ( the rod at the top center) open or closed? With it closed, you may get a lower draft reading due to the longer pathway of the flue gases. Especially with coal.Waswood wrote:I called DS and they said a .06-.08 is a good draft . With these warm temps I was hovering in the .08 area.

Top damper was closed to let reburn work . Also bimetal air was closed, only air was top air and it was set at 1/2 open . It was just a small wood fire for the evening.SWPaDon wrote:Was that with the stove damper ( the rod at the top center) open or closed?

Just curious. Some on here have said not to set a baro with a wood fire. I dunno, I've never used one myself. I've only ever used a MPD.Waswood wrote:Top damper was closed to let reburn work .

That draft they recommended seems kinda high to me. My chimney would only hit those numbers if it was below zero outside and pushing the furnace hard.Waswood wrote:I called DS and they said a .06-.08 is a good draft .

During these mild temps, my draft wanders between -.01 and -.02. I have my baro set to limit at -.03. I don't like to see it ride past -.04.
I think that stove would run just fine with -.03 to -.04. I don't understand why they want the draft so strong.
I disagree with using a baro for wood. It can lead to problems.

According to DS it will help keep your wood fire from burning to hot . I explained to them I'm only using wood when temps are warmer. They said it didn't matter which damper just 1 was manual and the other automatic. I always used a manual on my old stove never tried the Baro . Like others said I guess it's poss for a Baro to feed a chimney fire .SWPaDon wrote:Just curious. Some on here have said not to set a baro with a wood fire. I dunno, I've never used one myself.

I talked to them when I bought the stove and they gave me the impression they were worried about not enough draft and co problems that's why they originally said no damper. Now they say most people don't have that good of a draft ... So I guess it's ok to slow it down . Why do you say wood can cause a problem with Baro? Because of the feeding a chimney fire?Lightning wrote:That draft they recommended seems kinda high to me.

It's thought that by introducing cool air into the flue gases with a wood fire, it would cause creosote to form and cling to the chimney walls more actively. Plus the chimney fire feeding thing.. It's also thought that creosote will deposit on the baro door, throwing it out of adjustment.

Ok I understand that. So here's another question . Does the Mano change enough when you burn that you are always making adjustments to a manual damper? my old wood stove had a manual and it was 75 percent closed 90 percent of the time. Basically only opening it to reload and it worked fine .But then again I didn't have the Mano hooked to it letting me know what the draft was.Lightning wrote:It's thought that by introducing cool air into the flue gases with a wood fire, it would cause creosote to form and cling to the chimney walls more actively.

I'm thinkin that will be fine WW--are you burnin yet??? If not, why not? It ain't rocket science & the only way to do it right is to do it. Most of us come from a wood background. Me?? 40+ yrs worth. Still got the wood beast in the back part of the house..

I have been burning but had to let the coal go out due to these temps around 70. Had the wood fire last night ( 1st fire with the Mano) just to knock the chill off. Later this week highs in the low-mid 40s it will be coal time again . prob is looks like another warm up coming next weekfreetown fred wrote:I'm thinkin that will be fine WW--are you burnin yet???
