These are projected dimensions and specifications for our new steel hybrid.  They won’t change much, but as noted below don’t build a hearth or install a chimney thimble based on these specifications.  EPA testing is scheduled to begin in 3 weeks, with UL testing (clearances) following immediately thereafter.
Target Dimensions and Specifications:
Do not build a hearth or chimney until you have confirmed dimensions.  If you do, we are not responsible!
