Hi, My local stove shop and reps from both Travis Industries (Lopi, Avalon) and Pacific Energy have all told me that using any compressed wood bricks/logs will void my new stove warranty. My local stove shop installer told me that burning one compressed log/block is ok but anymore than that will over fire the stove. He said that compressed logs burn fine in fireplaces and inserts but not wood stoves. I am about to get a Lopi Endeavor installed (my first wood stove) and am having trouble getting seasoned wood. I thought I fixed the problem when I ordered two pallets of Envi blocks. Now I am thinking of canceling the order as not to void the 7 year Lopi warranty. There are many different types/quality of compressed wood products. Surely some of them must burn appropriately in a Lopi or PE stoves. Should I cancel my Envi block order? I have until tomorrow morning to cancel the order!!
