new furnace wireing

Hi,
Im new here and have one easy question. Im installing a new patriot 80 oil furnace, just replacing a out dated oil furnace to this new one. There is 3 black wires and 3 white wires comming out of the new furnace to hook up to the power. the white wires are hooked together and the black wires are hooked together out of the new carton. Do they all stay together when i hook them up to the wire that use to go to the old furnace. I didnt change anything from the service panel of the house. the old furnace just had one white and one black comming out of it.
thankyou

 

What does the install manual say about this wires?

I'm going to say wire it all up together, but I don't have the manual, so you'll have to look at it on your end.

 

The diagrams I see here http://www.heatcontroller.com/produc...046432K001.pdf
show only 1 or 2 blacks & 2 whites.

 

thank you that manual shows 2 wire, but mine is three my manual shows three. i left them bundel in three and hooked it up and fired it up last night and it ran fine

thank you
