Anyone use a manometer?

[tkirk22]

I'm curious. Does anyone use a manometer to measure draft?

Is there one pressure differential number that's right or does the draft spec vary between stoves?

I have a couple very accurate pressure sensors in my toolbox of nerd chit so wiring one up is not a big issue. Also I think I may have an overdraft issue and I'm wondering if a draft reading would help me figure out how much to close off the secondary air.

I think we have a few on here that either actively use - or have used - manometers to measure the draft. If you have a sensor, it would be a neat project to hook up and see how the stove runs. Although the overall accuracy of the sensor doesn't mean much in this application - the big factors are going to be the range of the sensor (most stoves draft in the .02-.06 inches of water range) and the precision of the sensor - you want to be able to get the same reading at the same draft every time.

I used one a couple times to measure pellet stove draft. Works ok.

We, of course, have multiple pressure sensors (Inclined manometers and electronic pressure transmitters) here and obviously use them to measure draft extensively.


If you're measuring your draft, we can give you a pretty good idea if you're overdrafting or not, based on what we usually see from the stove in the lab.

Thanks for the replies. I think I'll plan on doing this for next year. What sort of draft numbers should I have for a 13NCI?
