I am wondering if there is a clearance requirement from one b vent to another. I saw an older home today with two wall furnaces. The b vents run parallel to one another and terminate right next to one another. Clearance to combustibles is fine and the vents are properly terminated above the roof. While the install appears odd I can not find any reference that it is improper. Ideas?

Clearance is to combustibles. Is either B vent combustible? No.

From b vent - InterNACHI Inspection Forum http://www.nachi.org/forum/f20/b-vent-99827/#ixzz3VW50QgWp
I was thinking more along the lines of leak potential at the cap area since the pipes “terminate right next to each other”.
