I appologize for basically no info on the furnace. It's a Miller cmf2 80 po conv. For a mobile home closet type [so #2 heating oil] I removed the old one, just the thermostat and power hookups were simple, now there's different options, or color coaded wire's for the power, and the thermostat box has more options. Thought I'd be able to copy the old

Basicall the power for the unit should be 120 volts. One black one white and one green OR bare wire. Just wire them color to color and the bare or green wire goes to ground.

Thermostat wire is usually red and white for heat only. Here again a simple R to red and W to white on the furnace low voltage terminals..

Thanks hvac, the more I looked at it the simpler it gets, but it's nice to be able to get an answer. Very much appreciated!

Your welcome. Stay warm.
