located 8' or more from a portion of a building
which extends at an angle greater than 45
upward from the horizontal may terminate in
accordance with Table 1 (Figure 3 ) , provided
that in no case shall any discharge opening on
the cap be less than 2' (610 mm) horizontally
from the roof surface (National Fuel Gas Code
ANSI Z223.1 (NFPA 54) 7.6.2) (CAN/CGA B149).

Multiple Terminations – These appliances
may vent adjacent to and at the same level with
any other gas appliances (including direct-
vent appliances) provided that there is at least
2 ft. (0.6m) between the proximal edges of the
vent caps. These appliances may be vented
adjacent to a chimney vent servicing a solid
fuel fireplace provided the B-vent cap is at
least 2 ft. (0.6m) away from the nearest point
of the chimney opening.
