1
Recommended heating area and maximum burn time may vary subject to location in home, chimney draft,heat loss factors, climate, fuel type
and other variables. The recommended heated area for a given appliance is dened by the manufacturer as its capacity to maintain a minimum
acceptable temperature in the designated area in case of a power failure.
2
The maximum heat output (dry cordwood) is based on a loading density varying between 15 lb/ft
3
and 20 lb/ft
3
. Other performances are based on
a fuel load prescribed by the standard. The specied loading density varies between 7 lb/ft³ and 12 lb/ft
3
. The moisture content is between 19%
and 25%.
3
As measured per CSA B415.1-10 stack loss method.
4
Higher Heating Value of the fuel.
5
Lower Heating Value of the fuel.
6
Optimum overall efciency at a specic burn rate (LHV).
7
This appliance is ofcially tested and certied by an independent agency.
8
Tested and certied in compliance with CFR 40 part 60, subpart AAA, section 60.534(a)(1(ii) and draft ASTM WK47329-14
