Selecting furnace - a few questions

First of all, where does one buy a furnace? I have a Grainger near me that sells Dayton and I have to go through a middleman to get any of the other brands? Or is there a place I can just order one?

Secondly, I don't have the flue space for a metal venting furnace, so it has to be a PVC. So, for example, this furnace here:
There is info about the venting size (2" to 3" depending on the run) but nothing about the venting type. How to know for sure?

BTW - has anyone ever ordered from That same model is significantly less over there...

Selecting furnace - a few questions

You generally buy a furnace through a licensed contractor, who will install it safely and correctly for you

Seriously, if you're not even sure what type of vent to use, and you're selecting your furnace based on the amount of space you have for the vent, I'd serioulsy reconsider making this a DIY project. 95+ furnaces can be tricky to install and setup correctly, and an improper installation can have deadly consequences.

FYI: All 90+ furnaces vent with standard DWV PVC pipe. The vent must be installed according to code, and in many areas codes would not allow you to self-install a furnace.
