Putting the manual between the barometric and the stove won't influence how far open the baro door opens.

Putting the manual after the barometric will, but is not recommended due to possible CO leaking. I would only try it if you have a manometer installed. I just started a topic on just that same scenario.

Why not? My thought was, slowing the passage of hot flue gas into the chimney should result in less hot air in the chimney, therefore less draft, therefore less need for the baro door to open.

Yes sir, That makes sense, but that's not what I've observed to happen. I've tried it. As long as the chimney is warm, it continues to pull the same.

The baro's operation is a function of pressure, not volume...
You could have the same pressure whether you have a 1" pipe, or 6" pipe.
It's the volume that differs.

Finally, i have my crazy "industrial leave vac." chimney under control.

the current series of controls is

stove

Dwyer pick up line

MPD

Baro.

MPD

wall thimble

the lower MPD keeps heat in the stove, the upper MPD brings the draft down to where the Baro. can work as intended to prevent over draft during higher winds but not produce a constant draw of room air out the chimney 24/7.

last night i had 6-9 mph winds and could not induce the stove to go positive with both MPD's closed while the Baro. and intake where held wide open. the mano. reading was -.005.

i'm satisfied for now.

Manual pipe damper = instant death by monoxide, turn your house into a lethal gas chamber within minutes, should be banned by local/state/federal law and anyone caught using one in a home with children is prosecuted for child abuse, need to get them all off the hardware store shelves IMMEDIATELY and hire gestapo to go door to door and confiscate all that remain in private hands and melt them down in a blast forge.

Baro Damper= best invention since the polio vacccine, can heat 12,000 sq foot house all winter in Alaska with 1/4 ton of nut, sometimes even get heat with NO fire in stove just by gazing at baro damper, not having one is akin to going 125 mph down a mountain road w/ no seatbelt, if you don't have one get one yesterday folks ALL PRAISE THE BARO DAMPER HALLELUJAH AMEN!

Just in case you were serious-------Speakin of gestapo--you do understand that your little rant about MPD's is unadulterated bullshit. I don't know where you get your info from, but it's validity is lacking muchly--don't be spoutin crap that apparently you have little knowledge about, there's enough BS floatin around out in the world in this day & age. PS--just for the record--lighten up on what ever drugs you're abusing :drool: :eek2:

Hey Fred, did you swap out the manual damper for a barometric yet?

I don't have one either. The baro is WIDE OPEN and making a sucking noise...I think that means I have enough draft.
