Hello, My husband and I are new to heating with wood. We are in the process of installing a Woodstock Keystone stove. The stove will have a rear heat shield as well as double-walled pipe. My question is what clearance is safe for using wood on the wall behind the stove and having a wooden mantel? If using tile behind the stove, how about with a wood mantel. I would really love to re-purpose pallets for the wall, but we have a very small house so this may not work with the space we have available. Thanks for any help and advice.
