Honda 2000 won’t run my late model home furnace

So forgive my lack of electrical knowledge but is all that I would need to do is get a 110 plug, then run a small jumper from the ground to the neutral(white/silver) side of the plug and plug that into the generator?

My assumption is that instead of using a 110 plug I could also do it for the 30 amp outlet on the generator and therefore free up a 110 outlet. My genny has 2 - 110 outlets and 1-30 amp outlet

Thanks
