Your furnace will run just like it normally does. You need to have an
electrician install a male plug at the furnace, connected to a single pole
double throw switch. In one position the furnace gets its power from your
electrical system, and in the other position it will get its power from an
extension cord plugged into your generator.

I want to get a generator just to run my furnace fan if the power goes
out during the winter. We are in the Boston area, and the snowstorms
are pretty fierce. I know that 3750kw will be plenty of power for what
I need, but is this as simple as running the generator outside, running
an extension cord into the basement and plugging my furnace fan into
it. Or I guess, plugging everything in, and then starting teh
generator.

Does the generator run even when no power is being drawn from it. Also,
would the thermostat work without power? What about the furnace itself?
