Co readings from woodstove

[Deleted User]

what the wood fuel setting on a Kane May Quintox is for. It even comes set up for a variety of coals in addition to multip[le kinds of fuel oil, multiple gases and wood, out of the box. Way cool. Good value too. Contact kirstyu@ueitest.com no relative.

CO readings from woodstove

Just curious if anyone has done any cumbustion analysis in the flue of an operating woodburner. At full fire I would think the readings would not be that high, but when the unit goes into 'idle' and is producing all of the dense smoke out of the stack, i wonder what the readings would be. mark Hunt?? i susoect he would know.....

Nobody in their right mind would hookup their analyzer to a wood stove...
unless of course they want to buy a new analyzer.

Smoke and analyzers don't mix.

I've never tried my woodstove, but I got about 260ppm with my tester over the kitchen stove with 2 burners on high cooking the other night...was only about 5-6ppm in the rest of the room.

know a bit about testing wood burners with a combustion analyzer. Chat with them.

Be sure to check CO around the outside of any wood burner. Often times they are not provided enough, or any combustion air. they will suck it from somewhere, often down the WH or furnace flue!

I know my analyzer didn't like my diesel truck exhaust. It took a trip back to the factory after that trick

OK, I'll admit it.....

Ive tested my woodburner several times - mostly when the power was out and I was bored....

At it's best, it runs with a 15%O2, 550 stack and around 6,000ppm CO air free and an sse in the low 50% range....

Suprisingly, I've yet to just outright kill a sensor, but sure have put a dent in a few!!

Propane cooktop results

I tried my fyrite pro 125 over one of the burners on my propane cooktop and never got more than about 45ppm CO. It was very dependent on the position of the probe. I think it went down to 10ppm when the draft hood was turned on. I wish there was a device that automatically turned on the draft hood when any burner was turned on, but I can't find such a thing. Now I need to get a CO alarm in the kitchen...

Wood Stoves

Wood Stoves, Fireplace, Furnaces can put out anywhere from 500pp to 10,000ppm or more depending on how they are burning, what kind of wood, if they are smoldering etc. I have worked on some industrial wood furnaces and the CO reading is used to adjust the under and over air to create maximum burn. Also use it to adjust residential wood furnaces. If the analyzer couldn't handle smoke it couldn't be use on oil.

If the top burners on a stove are producing more than 100ppm of CO they are definitely out of adjustment. They should put out less than 50ppm.

Each burner...or all combined?

Wood and CO


As Rudy and Jim have mentioned, CO from wood fired products tend to be very high.

I've tested a few but my Fyrite 125 doesn't go to 10,000ppm.

Each burner independently.

Well ,Tim, yours is a timely comment

Everyone thinks it is the turkey that makes them sleepy on Thanksgiving day, when it is actually cooking the turkey that does it!
