TEST STANDARDS
Heating capacity* – BTU/hr., EPA test wood :
Heating capacity* – BTU/hr., seasoned cordwood :
Maximum recommended heating area : 500 to 2,700 square feet
Optimum efficiency : 78%
*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.
