You can have a good draft reading in your pipe and still have a poor reading in the combustion area of the stove. It is possible to have a sulfur odor(sulfur dioxide) and have no CO present. However the sulfur smell is usually a precursor to the eventual release of CO. In any case the draft in the stove is to low to overcome the air volume created by both combustion fans and needs to be checked and corrected immediately.
Don't worry about me, I'm not dead yet. Still have the smell, but I just shut the stoker down. I think it's the chimney - I don't have a chimney cap and I had a couple of dead birds at the start of the season so I think they might have a nest in there. I'm going to try and take a look this weekend to see what I have. In regards to the CO detectors though, I have a couple throughout the house and none of them are more than 3 years old so I doubt they are all lying to me. Other than the nasty smell, I've had no indications that there is CO in the house. It doesn't take much of a sulfur odor to stink up a large area so I'm sure the presence of the actual exhaust gases is minimal. Thanks for the input though and I'll let you know if I find something in the chimney

I doubled up the gaskets and the "glow" has reduced quite a bit so the seal should be better, but the door is a bear to close now.

I have a manometer hooked up and am pulling -.05 in wc and have my blowers running full time - no more tri-burner. This is the first year I've had this new configuration and the first year I've had this much trouble with the odor. In addition to this, I've added a chimney cap. I need input on this because it's really pi$$ing me off at this point. The only way I've been able to beat is so far is by running 1 stoker and taping over the hole for the second blower. Should I try sealing up the barometric damper to get all of the draft through the stove?

I'm not familiar with your stove but said it occurs when your second stoker runs. The second stoker probably brings on a second combustion fan which may be over pressurizing the combustion chamber. I don't want to open up the whole sulfer smell debate again but there should not be any sulfur smell unless its when you have the combustion door open briefly.

I believe the second stoker is overpressurizing the combustion chamber, but I don't see how I'm supposed to fix it. My manual says that the draft should be between .04-.06 in wc and in my opinion, this should provide enough "flow" to remove the air being added to the combustion chamber considering that they designed the stove. I am grabbing some fittings from work today to check the pressure in the firebox.
