wall venting 60,000 BTU fuel oil furnace

i have a 60,000 BTU furnace with an 8" single wall flue going into a 12" double wall flue through the wall. The heater sits in the corner of the crawlspace next to the outside walls. This vent goes out the crawlspace (6' high) and up the outside wall of my house for two stories. This is a mountain home. Two questions here. how can I calculate the proper flue size? Second, the flue is ugly, and am wondering if we can simply terminate the vent to the outside wall? Thank you, Steve

No, you can't just terminate it outside the wall.
In order to do so. You would need to install a power venter. Which are usually somewhat noisey.

If your flue from the furnace/heater is 8", you can't decrease the chimney flue size.

When calculating flue/chimney size. You would need to know BTU input. Lateral rise, chimney height. Then look up the size in the IFGC book
