inexpensive prototype with tin flashing (like roof flashing) it will not stand
up to heavy use, but it's easy to shape with tin snips and adjust to the right
size. Getting the adjustments of the skirt, the right spacing between the
stove and the pot and the skirt is very important and it may take a couple of
tries. (The wok supports have round holes, you may tinker with it and
discover whether you need them). You may also need some form of additional
support under your larger pots, which is another thing to consider if you are
building something. Once you know what you need, use that for a while, or have a
local metalworker build it in steel (no galvanized). Stainless is
prettier, more durable and more expensive.<o:p></o:p></SPAN></P>

PLEASE keep opening your windows/doors. With no stove pipe (no above the

part of the original problem (based on an assumption - always risky, so I'll
check).<BR>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.<BR><BR>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.<BR><BR>All speculation, but I bit my boot so deeply on the last one, I

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. <BR><BR>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.
