Vent Pipe Types
Only use Type L vent pipe. It uses an expensive stainless steel liner but it will last. Typical costs are around $35 for 2 foot of type L.
Do not use Type B vent pipe. It will be tempting because it is so much cheaper, around $20 for a four foot section. But, it will only last a season or two before the corn gasses corrode type B pipe and you will be breathing Carbon Monoxide.
Something new on the market, AL29-4C vent pipe is a a superferritic stainless steel designed for extreme resistance to chloride ion pitting, crevice corrosion and stress corrosion cracking, as well as general corrosion in oxidizing. It is an ideal choice for resisting deleterious effects of corrosive condensates created by burning corn.
