Barometric damper location pictures included

[goosegunner]

I have been trying to fine tune my Econoburn 200. I installed a thermocouple right in the flue collar and saw temps as high as 640 with clean tubes. I moved the thermocouple to 15" above the center of the flue outlet and see temps in the mid 450 and less. But I have a barometric damper letting in cooler air. If I hold it shut the temp rises quickly but so does the draft. I am monitoring it with a Dwyer manometer.


So here is a picture of the damper install. It does maintain the correct draft but will it hurt anything in this location?

I have considered moving it but I am concerned about sparks in the boiler room. I have had the occasional puffing the slams the damper.

I'm not up on the specifications or recommendations, but that looks like a pretty good place for one to me. Seat of the pants says that since the smoke will be shooting straight up to the exit point from the point they get cooled by the BD, there would be less chance for creosote condensation & buildup. And there will be no creosote buildup on the damper itself. And it is doing it's job in regulating draft.

If there is concern about sparks coming out, could you put an oversized pipe cap over the BD to act as a baffle? If I explained that right.

I still might cap it with some type of screen. Maybe like a 8" metal kitchen strainer. The ones that look like screen.

Or use a cap and cut our area for screen material.

Do you have the damper mounted below the exhaust outlet?
I don't know why but I always thought it's to be level or above.
Got me wondering if your location will stop the fumes better.

Yes it is below the exhaust level. I don't get anything coming out of it unless I forget to open the window for make up air into the building.

I do get ash in the cap on the bottom of the barometric damper T.

I have used mine there for a few years now. I taped a small chunk of metal inside my damper so when i did get a puff it did not push my damper all the way open.(past fully closed)
