VERTICAL VENT
TERMINAL LOCATION
The location of the vertical vent terminal depends on
the following considerations (see Vertical Vent Terminal
Location Figure on previous page):
1. Minimum 12 in. (30.5 cm) above roof. Minimum 18"
above roof line for Canada.
2. Minimum 12 in. (30.5 cm) above anticipated snow
level.
3. Maximum 24 in. (61cm) above roof level without
additional support for vent.
4. Four (4) ft. (1.22 m) from any gable, dormer or other
roof structure with building interior access (i.e., vent,
window, etc.).
5. Ten (10) ft. (3.05m) from any forced air inlet to the
building. Any fresh or make-up air inlet such as a
dryer or furnace area is considered to be a forced air
inlet.
6. Maintain a minimum horizontal distance of 12 in.
(30.5 cm) between the vent and combustion air-inlet
terminal centerlines.
7. Maintain a minimum distance from the vent and
the combustion air-inlet terminals of not less than
12 in. (30.5 cm) above grade or average snowfall,
whichever is greater.
