I was perusing the Hearthstone site for an answer to a gas question & found this in the FAQ section:
Can I burn BioBricks in a Hearthstone woodstove?
No. Our wood stoves are tested and certified with natural cord wood only. Burning properly seasoned cord wood in your HearthStone stove will produce a clean burn that exceeds the EPA efficiency requirements. BioBricks, and similar manmade products, can burn too hot and fast to be a good source of fuel, and may cause the stove to overheat. Keep in mind that damage due to over-firing will not be covered by the warranty.
Not trying to raise a ruckus or anything... Once you've bought YOUR stove & it's installed in YOUR house, I suppose it's YOURS to do what you want, but there it is, right from the people in the know...
