Venting Requirements for Biomass Stoves

[vgrund]

This question is mostly just being driven by my curiosity. I know that burning 100% corn requires special venting material. If one burns a 50/50 combination of wood pellets and corn, does one still need more expensive corn-rated venting?

If your owner's manual says it does, then , in a word, YES

The special venting is required because burning corn produces products that are corrosive, burning a mixture just produces a smaller amount it doesn't prevent it from forming so the answer is yes.

I did a search on corn in the Mt Vernon AE manual (an insert I'm considering). It does not address it in any way, whether 100% corn or a mixture.

Start out with the good stuff, Dura Vent Pellet Vent Pro and never have to worry.

The manual says PL or L venting is to be used. It however is silent on what gets used when.

PL vent pipe is rated for both wood pellets and grain (corn), type L is rated for wood pellets.

So as they say pick your poison, my bet is the PL will stand up a lot better than the L when burning any quantity of corn. I wish I could remember where I saw a picture of some vent pipe after being used with corn that wasn't rated for it Holey would be the word I'd use to describe it.

Great info, thanks! I missed the "PL" or "L" reference on page 13.
