[Greenbuilding] [BULK] Re: Question on tight house, carbon monoxide

You may want to buy/build a pot skirt (similar to a wok support - if you've
seen those). That will help the heat transfer, I don't know about the carbon
monoxide. This is a good, if slightly technical analysis of pot skirts:

Very Important!!! PLEASE keep opening your windows/doors.  With no stove
pipe (no above the cooking zone ventilation  to the outside), and a very
tight house, those CO readings you are seeing are depressingly normal, even
in the most efficient stoves, that's why venting is so important.  Shoot, I
can set off the CO alarm at my house on my electric range in my drafty
kitchen.

Yes, the canning and soup pots are larger than regular pots, significantly
larger than the circumference of the flame. No soot, however.

One other thought though, on part of the original problem (based on an
assumption - always risky, so I'll check).
If the canning pot is larger than your normal pots and pans (most seem to
be), could the key to the high CO production be that the flame is impinging
on ( flaring out across) the bottom of the pot?  This will tend to reduce
the combustion efficiency (in extremes even soot up the pot bottom,educe
combustion efficiency and increase the CO production.

I'd expect the oven to be set to burn relatively efficiently, so we don't
hear of cooks keeling over, and produce less CO even when on for longer
times.

All speculation, but I bit my boot so deeply on the last one, I had

I actually watch them quite closely to keep them from boiling over. The CO
level goes way up before they do occasionally boil over, however,
definitely. The CO level goes up when the flames are burning properly blue. 

No way could I have the stove vented outside when the house was built
without huge additional cost--I had an expert builder and confirmed this at
the time. Thus the alternative, a vent with carbon filter. No, it is not
against code, at least not here, definitely.
