Hello,

I attempting to measure draft for the coal stove. I have a manometer. What setting/unit am I suppose to measure? I have the following options... inH20, psi, bar, mbar, kPa, inHg, mmHg, ozin, ftH2O, cmH2O, or kgcm.

If I had to guess would be inches water (inH20), but not sure...

Thanks,
Paul K

You will be using hundredths of an inch of water.

That'd be the one I'd choose.

That'd be the one I'd choose. Be sure to favor the negative side.

excellent thanks, still reading up on it... Now to figure out why that powervent has a damper/restrictor plate in it you can adjust...

typically, INCHES of H20 and will be .02-.04 normally. can vary a bit depending on temperatures. but power vents/direct vents are pretty constant draft.

My Keystoker direct vent has a slider plate to adjust the draft. i measure directly on the side of my stove.

mine was coming up 0, adjusted it to .4... want to test again in the morning cause I shut it down and cleaned some of it today. Its been set the same way since day 1, but sometimes I would get a sulfur (or something smell). Usually that let me know it was time to clean it.... .... I have co detectors all around, none ever went off... digital one has been at 0 since i got it.
