I think I have enough draft

PostBy: warminmn On: Sun Jan 26, 2014 10:25 pm

I just had to share this. I was reloading my Chubby just now. MPD open, baro covered over. Stove running 400. 8" brick chimney in the center of house roof. It is zero degrees and dropping. 33 MPH wind, gusting to 43 and Im on the prairie. My mano was jumping all over the place and really high so I tried to get a pic of its peak. I saw it go over 1 but wasnt quick enough with my camera. Heres the highest I caught. With my baro uncovered its back down to .05-.06 and there is a ton of air going into it. Think it would hold a bowling ball? LOL

Christ,I think you've made it as far as Draft is concerned! You think you might be pinching back those plans to get a Draft Inducer? :dancing: :rofl: :doh: :bag:

Maybe I could run a stoker without the blower, LOL

I just rechecked it and its down to about a third of where it was. Still high but not crazy like before. My old house is probably more tight then most 100 year old homes but plenty coming in with the strong winds.

I don't mean to steal the thread...but this reminded me of a experience I had a few years ago.
When I first dropped a 25ft 6" flex pipe down my parents brick chimney (center of house) - it was a fair wind coming on off the Atlantic Ocean in northeastern Mass.
As I let the flex pipe sit on the floor of the fireplace - prior to moving the wood stove in place - I nearly couldn't get the flex pipe lifted off the floor it was sucking so hard.
When I finally did...I was able to angle it so I could vacuum up any loose mortar and little pebbles that had been on the floor - I could here them getting sucked right on out as they rattled up the pipe.
Never seen anything like it.
I don't know what a manometer would read with suction like that.
And all that suction - the flex pipe was just free floating in the chimney - I hadn't yet blocked the sides of the flu.

As much as I'm against mano's for my coal stove - if I had went with a coal stove for my parents - I would have been swayed to the dark side and used one.

during the height of the wind here last night about 10 pm i had a sustained neg. .2 on the mano for a full 75 seconds.

EDIT, that was with both MPD's completely closed, pretty shocking.

Before installing the baro I saw a high of .27 with the MPD open & no wind gusts outside. Even with it closed the average draft was over .1. Now it stays in the .04-.07 range with the baro & MPD when it's really cold & only the baro on days like this (40°).

It's been gusting here in the N.East also. I thought the baro was suppose to controls these symptoms, but I guess they're limited. My door has been flopping around a little too. Wonder if that's what's been killing my burn times the past 12 hrs or so?

I see my mano spike just for a moment during windy situations. If you are seeing a steady reading higher than what its set at (-.04?) It could be due to a steady wind. Even severe cold makes mine read higher than what I have it set at, like when it gets under 10 degrees mine will start to wander up to -.04 to -.045 (I set mine to -.03) I suppose it would shorten burn time a little, but the trade off would be a little more heat. If you were to graph your mano readings, you would see that the baro shaves off the peaks as compared to no baro.. So it does control those symptoms - but during extreme conditions, you will still see some fluctuation..

Well as you know Lee, my baro hasn't been in there very long, and I was always impressed how steady it's been keeping the draft, (for the short amount of time I've been monitoring it.). This is the 1st I've seen it dancing. I did actually adjust the weight for a slightly higher draft the other day. (From -.04, to -.05-06) for a little extra heat, but the past few days, it's magically returned to -.04.

Very Funny Lightning!

jjs, you had a barometric vacuum cleaner.

Everythings back to normal now except too cold.
