How do I wire this thing up? I have a black wire, white wire and ground from electrical box. The wiring instructions are very vague, and not really of much help. There are 2 black, and two red on the thermostat that goes to the heater. There is one black from the thermostat on the heater, and one black from the heating element. Thank you for any help you can offer. Randy.
You should have a licensed electrician connect this for you.
You did not specify the voltage. Baseboard heat comes in different voltages. If you connect a 240v unit to 110v it will work but only put out half of it's heat.
If you connect a 110v unit to 240v you will start an instant fire.
There should not be a thermostat on the unit and another on the wall. You can buy units for each application. You are probably looking at the thermistor which is a safety device which opens the circuit when there is too much heat. It must remain wired in series with the heat coil.
Also note that it is a violation of the National Electric code to install electric baseboard heat underneath an existing outlet. It is also common sense to not install it under drapes or near anything else combustible.

if ur are replacing the heater and it was originally 220/240 ur wiring should b ok but to b sure trace the line wire back to breaker panel and look at breaker the white and the black should b hooked up to separate breakers if the white is hooked up to a ground bar usually on the inside side of the panel and the black hooked up to breaker ur line is 110/120 and will cause problems when hooked up. if the lines r 220/240 than red can hook up to white and black to black
this heater can usually be wired from either side. meaning your wiring can be brought through the wall inside of one side or the other.
the wiring you bring in to this unit needs to be 12g or larger.
it needs to be on a dedicated circuit. that means you cant splice into any other line. it needs to be for your baseboard heaters alone. that is code and wouldnt want to sleep in a house with baseboard heat that didnt have a dedicated circuit.
baseboard heat is most economical to run with 240v units. 120 is going to cost more to run.
you will need a thermostat either built into the unit or a thermostat unit mounted in the wall to run it.
dont mount the thermastat over the heater. I shouldnt have to explain why.
a 240 volt circuit run from your panel on a 20 amp breaker consists of 3 wires, a ground and a black and white.
in a 240v configuration both the black and white are hot and you must wrap some black tape around the white wire where it shows in your breaker panel and at the handy box in which you have installed the thermostat and then where it enters the heater. this re-designates the wire as a hot instaed of nuetral this gives you to black hots.
you hook the white and black wire to the line in side of the thermostat which should be the two red wires.then the two black load out wires of the thermastat run to your heater. hook your ground (green or bare) to the box if its metal and pig tail it to the ground screw on the thermastat, then out of that pigtail to the heater along with the two hot wires.
you will find a bare ground solid copper wire fixed to the inside connect your ground.
you will find two other wires they are both hots you will connect one of your hots to one of them and the other to the remaining.
what it looks like is an element sitting in the housing the housing is the baseboard and you have a hot wire running through a wire way to the other side and connecting to it and one hot stays on the side you brought the wires to.
in other words since you can wire it from either side you have to have a way to get the energy to one side or the other and they supply a way.
as long as this is labled as a 240 unit both wires are hot. take the covers off both ends you will notice the wire traveling from one side to the other. your goal is to have one hot connected at one end of the fillament and the other hot you brought in to the other end. the best way to hook up multiple heatrs is to have branch lines from the thermastat toeach heater, not to daisychain them one to the other becuase you will have voltage drop as a heater is using it before passing the voltage down the line leading to poorly functioning heaters
I hope you are using a Line Voltage Thermostat!! First, make sure that the power feeding the thermostat is coming from a two pole breaker of the correct amperage (20 amp). If you are using 12-2 wire with ground then please mark the white wire with black tape at each end to identify it as a HOT power source and not a Neutral wire (which is a grounded lead). Do the same for the 12-2 wires feeding the baseboard heater from the Line Voltage Thermostat. The wires from the thermostat (One Black & one White w/black tape) will be wired to each one of the two wires (one Black & one Red or two Black wires) at the baseboard heater. It doesn't matter which wire from the thermostat is wired to which wire at the heater, just as long as there is one wire to one and one wire to the other.(eg. Black from stat to Black at heater/White w/blk. tape from stat to Red at heater OR Black from stat to Black at heater/White w/blk. tape from stat to OTHER Black at heater). I have seen baseboard heaters with two black wires or one black and one red wire. Hope this helps, but if you are confused then please have an experienced tech. do it for you.
The Black Wires from the md26 are your load(the heater) and the red lines are your line(power). The lines are also paired up on the thermostat with a red and black on the left and are red and black on the right. In the actual heater connect the black to the black wire and the white to the white and connect the grounds. In the thermostat connect the black from the heater to left side black( remember there are pairs left(black, red) right (black, red) and the white to the right side black connect the black from your power to the left side red and the white from your power to the right side red. Should be ready to go.
There should be a wiring compartment at one of the ends of the heater 1/4 inch bolt holding the compartment shut. the link below will show you generally what it looks like rate me FIXYA! if this works.Good Luck.Oh yeah If I misinterpreted your question leave me a comment.
