[*]
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 defined by the manufacturer as
its capacity to maintain a minimum acceptable temperature in the designated area in case of a power failure.
(1)
Values are as measured per test method, except for the recommended heating area, firebox volume, maximum burn time
and maximum heat output.
(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 specified 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 efficiency at a specific burn rate (LHV).
(7)
This appliance is officially tested and certified by an independent agency.
