Barometric help

PostBy: Gentleshepherd On: Sat Nov 16, 2013 8:58 pm

I have a Hot Air Keystoker and I re-routed my furnace pipes today and move my barometric damper from the end of a T to the MIddle of a T and it is now on a Diagonal T. I fired up my furnace today and can't get the damper to close. It stays open all of the time and that's even with the control set to the lowest or highest bracket. My question is this, can I run it with the damper open full bore? I can't get anyone local until Monday to look at it.

Thanks.

Make sure it's plumb. If it has two different slides for the weight try the other slide. One slide is for a vertical smoke pipe, the other is for horizontal. Diagonal is a crap shoot for which to use.

A line across the two pivot points should be level and the damper should close. If not I would block it off with aluminum foil until the draft could be read with a manometer and the barometric set .

FOr some wierd reason it started to work. When the Thermostat calls for heat and the fan kicks in, it now closes, and then opens up a bit when the cycle is done, I will keep an eye on it until I can get someone to look at it on Monday. I don't quote understand the almuninum foil concept, could you explain it for me.

A barometric damper keeps you from having too much draft over the fire and sending heat up the chimney. If the flapper is stuck open, the barometric damper will reduce draft over the fire, possibly to zero which might result in combustion gasses coming out into the house. Putting foil over the damper usually maintains the draft over the fire, probably too much draft but that will virtually ensure no exhaust comes into the house. You might lose some heat up the chimney with the foil over the damper but most likely all the flu gases will go where they're supposed to.

...cover the baro for now...or fasten it shut till someone can look at it-if your air handler is causing it to close...something isnt right- pics would be helpful

Photo 1 Shows damper closed when furnace is firing
Photo 2 Shows Damper whne furnace is done firing.
Photo 3 SHows damper about 30 seconds after furnace is done firing.

Everything seems to be working properly, no issues. Any comments would be appreciated.

It must take a lot of draft to open the baro door by the looks of where that weight is set. Do you have a manometer hooked up? I'm a bit puzzled too.. Tell us about the chimney. Interior? Height?

Is it me or is that shiny new T into which hangs a rusty old Barometric Damper fitted right after a diameter reducing ring???

Yes, that is correct, the old T was a 10 and I reduced it to a 9 to fit the damper.

The old T was a 10 with a reducer to a 9 to fit the damper.

Could that be the problem?

the sequence of whats happening in your pics seems fine...
i was under the impression that the baro was being affected by the comvection blower...(air handler)

Not sure. Might be since you didn't change anything else. Will have to ruminate over the implications a bit. Maybe others will chime in. My first inclination would be to have the same diameter damper as original smoke pipe diameter. Usually they recommend, if necessary, reducing diameter of smoke pipe at the thimble.

I would get a manometer before replacing any pipe or tees.. Its hard to guess what is happening. You could be sucking heat out of the stoker without realizing it if that chimney pulls that hard..
