*Why is the BTU indicated on the EPA label smaller than the one advertised?
You will notice a difference between the BTU output as indicated on the unit's white EPA label affixed to the glass
and the BTU as advertised on our web site and/or product literature. The maximum BTU output we advertise for
this unit is what will be obtained with a full load of seasoned cordwood inserted inside the firebox. The EPA output,
on the other hand, is what has been obtained during emissions testing. The EPA test procedure requires that a
special type of wood be used and positioned inside the firebox in a manner that does not represent the way the
firebox volume would normally be utilized using seasoned cordwood. The EPA test load is typically much smaller.
Hence, the BTU as per the EPA label is reduced. The BTU output that should be considered by a normal user is the
one we advertise for seasoned cordwood.
