New furnace, new placement, vent pipe horizontal run length allowed?

I know this depends on the heater and other variables, but in short I'm pre-planning a replacement heater and I want to use a different location, currently the furnace is horizontal in the crawlspace, I want to later use a high efficiency furnace where it can be PVC pipe vented and the furnace installed vertically, but I'd need a 6 to 8 foot horizontal run for the vent pipe. I'd have some space for some slope, but my question is if this is unreasonable and how much slope does this use typically?

Quarter inch per foot slope.
