(1<\/strong>)<\/sup>\u00a0Values are as measured per test method, except for the recommended heating area, firebox volume, maximum burn time and maximum heat output.<\/p>

()<\/sup>\u00a0Recommended 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.<\/p>

(2<\/strong>)<\/sup>\u00a0The maximum heat output (dry cordwood) is based on a loading density varying between 15 lb\/ft\u00b3 and 20 lb\/ft\u00b3 and reloading intervals ranging from 60 to 120 minutes. Other performances are based on a fuel load prescribed by the standard without any reloading between start and finish. The specified loading density varies between 7 lb\/ft\u00b3 and 12 lb\/ft\u00b3. The moisture content is between 19% and 25%.<\/p>

(3<\/strong>)<\/sup>\u00a0As measured per CSA B415.1-10 stack loss method.<\/p>

(4<\/strong>)<\/sup>\u00a0Higher Heating Value of the fuel.<\/p>

(5<\/strong>)<\/sup>\u00a0Lower Heating Value of the fuel.<\/p>

(6<\/strong>)<\/sup>\u00a0Performances based on a fuel load prescribed by the standard at 7 lb\/ft\u00b3 and with a moisture content between 19% and 25%.<\/p>

(7<\/strong>)<\/sup>\u00a0Optimum overall efficiency at a specific burn rate (LHV).<\/p>

(8<\/strong>)<\/sup>\u00a0The optimum heat transfer efficiency is for the low burn rate (using HHV) and represents the appliance\u2019s 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.<\/p>
