My 5000 W heater is wired to a double breaker (220V) 10 GA.black & white wires + grd.) feeding the heater (Dimplex). The heater element will generate only 140 degrees on the heater element surface tested by thermocouple meter lead.
Canadian Tech service says to use a SINGLE wire 220V feed?? The diagram clearly shows L1 & L2 along with ground.
1) is my wiring correct? 2) should I expect more heat from this 5000 W - 220V
Thanks for your advice
