Manufactured in Quebec from shavings that are 100% dry hardwood (6% to 7% humidity), wood bricks are very dense, thus ideal for heating over an extended period of time. Placing the wood bricks in a pyramid shape will produce lively flames. Placing the bricks side by side or stacked, produces less flame but will burn for longer. Producing very little ashes and only 60% emissions, it is the most economical heating product. Use 6 to 8 bricks at a time. The wood bricks generate 7800 BTU/lb.
