The Dettson Suprême Avantage SUP20-A240D12 ticks several boxes: wired at 240\/208 V on two wires, approved for copper or aluminum wiring, zero clearance and a multi-position design. It installs upflow, downflow with the DFB-SUP base depending on the floor, horizontally or suspended. Its published dimensions, 36 1\/2 in high and 22 in deep, help us confirm the location during the visit.\u003c\/p\u003e\n\u003cp\u003eThe aluminum approval matters in older homes in \u003cstrong\u003eLongueuil\u003c\/strong\u003e, \u003cstrong\u003eMontreal\u003c\/strong\u003e or on the \u003cstrong\u003eSouth Shore\u003c\/strong\u003e, where the existing supply circuit is sometimes aluminum. We always check its condition and capacity before reusing it.\u003c\/p\u003e\n\u003ch3\u003eWhat this model offers\u003c\/h3\u003e\n\u003cp\u003eThe furnace delivers 20 kW at 240 V and 15 kW at 208 V, or 51,256 BTU\/h. Its elements switch on in sequence, with a 10 kW first stage, and can be replaced individually. The 1\/3 HP direct-drive PSC motor, with 3 speeds, is factory-set to its high speed for heating: 1,150 CFM at 0.5 in w.c. Dettson publishes a temperature rise of 60 to 80 °F at 240 V.\u003c\/p\u003e\n\u003cp\u003eOn the front panel: continuous-fan switch, low\/high power switch, heat-demand indicator light and breakers.\u003c\/p\u003e\n\u003ch3\u003eWhat to plan for\u003c\/h3\u003e\n\u003cp\u003eAt 20 kW, the circuit is substantial. Dettson calls for a 125 A maximum breaker at 240 V (90 A at 208 V) and publishes a 103.5 A ampacity. We confirm that your electrical service can take it before recommending this model, and the quote spells out any electrical work required. If you are aiming for air conditioning, a coil of up to 3 tons can be added on the supply or return side. With a heat pump, Dettson does not allow the elements and the heat pump to heat at the same time; the K03081 interface manages the switchover.\u003c\/p\u003e\n\u003ch3\u003eInstallation by AirGreen\u003c\/h3\u003e\n\u003cp\u003eAirGreen is a family business established in \u003cstrong\u003eMontreal\u003c\/strong\u003e for more than fifteen years, holding RBQ licence 5645-9605-01 for ventilation, refrigeration and electrical work.
