I am currently buying a house with a 80% efficiency furnace that wasn't properly vented. When it was installed they didn't put a liner in the chimney. To solve the problem the sellers have aggreed to fix it. They want to install pvc pipe and vent it out the basement. Is this standard code and will it poss a safetly hazard

If it really is an 80% efficiency furnace, then must be vented using metal "B-vent".

I would be really looking closely at any other problems the home has if this is their idea of a safe procedure.
