Report "I'm replacing a non-hydronic electric baseboard heating unit with a Fahrenheat hydronic one. My old unit was 240v using 2 conductors plus bare ground wire. The fahrenheat (PLF series) unit's instructions are just a bit vague. The wires at the end cap are as follows: a) Two wires connected together with a crimped on connector b) A single green insulated wire with wire nut c) A pair of insulated wires (one red and one black) twisted together with a wire nut. The Thermostat is on the wall. The instructions say "Connect power supply to either end of heater by removing wirenut and connecting heater leads individually to supply leads""
