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.
2
The overall firebox calculation is an approximation and is not intended to be used for loading. This volume includes a buffer zone to allow an easier
fuel insertion, prevent ash spillage and allow the air wash to work properly.
3
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%.
4
As measured per CSA B415.1-10 stack loss method.
5
Higher Heating Value of the fuel.
6
Lower Heating Value of the fuel.
7
Optimum overall efficiency at a specific burn rate (LHV).
8
The optimum heat transfer efficiency is for the low burn rate and represents the appliance's ability to convert the energy contained in the wood logs
into energy transferred to the room in the form of heat and does not take into account the chemical losses during combustion.
9
This appliance is officially tested and certified by an independent agency.
10
Tested and certified in compliance with CFR 40 part 60, subpart AAA, section 60.534(a)(1(ii) and ASTM E3053-17 based on the ALT-125 sent by EPA
on February 28
th
, 2018.
