The % purity of ethanol has to do with the cost of purification. A standard industrial fractional distillation tower can produce 95% ethanol in one pass. 

 

Yes 

 

That's it. Anything above that needs a second or third pass, 

 

No.Cannot be done, the 95% alcohol:5% water mixture boils at a lower temperature than pure ethanol and will always remain 95%:5% at each distillation. To make anhydrous alcohol needs a separate process like passing it through oven dried cracked wheat. Search on positive azeotropic mixture 

 

Very few ethanol stoves have low CO, 

 

I believe you, all I was pointing out is that if it is producing CO it is also likely producing aldehyde
