I didn't think it mattered with just a two wire themostat it's just a switch that's either on or off telling the furnace to be on or off.
Well, when all else fails, match the one color that you have:
red to red and then hook the black and white together.
The most it will do is not work and you can switch them.

Line is power in and load is power out, as another answer said. A line voltage (120V, 240V) thermostat would have power in and out, which sounds like what you have. But if the old thermostat just had 2 wires, it might be a low voltage thermostat. How big are the white and red wires? You might have the wrong thermostat. If you don't know what you are doing, you should get a professional to help you. Even a low voltage thermostat if connected wrong could damage your furnace. There isn't enough information in your question to really help you get the right thermostat.

electrically speaking, LINE is power IN, LOAD is power OUT.
But, thermostatically speaking, if you only have two wires it doesn't matter which wire goes where. most old heat only system thermostats work off of 'line voltage' , actually millivoltage generated by the thermocouple. the thermocouple tells the gas control valve to turn the gas on or off.

line wire is the wire coming from the transformer feeding the tstat from the furnace....the load is the line going back to the control telling the furnace to initiate the start up sequence, if you have a 2 wire system either wire is ok, since what your doingis simply breaking the feed wire by the tstat going back to the furnance, ike a light switch in your house

Do you only have two wires going to your thermostat from your furnace, or are there more wires,, if so what colors?
