INSTRUCTIONS FOR VERTICAL VENTING.
The vent termination must be located as follows (refer to Figure 10):
a. Combustion air inlet must be 3 ft. (0.9 m) below any vent outlet that is within 10 ft. (3.1 m).
b. Vertical terminations shall extend at least 3 ft. (0.9 m) above the highest point where it passes
through a roof of a building and at least 2 ft. (0.6 m) higher than any portion of the building
within a horizontal distance of 10 ft. (3.1 m). Terminations that extend more than 2 ft. above the
roof must be laterally supported.
c. Combustion air inlet must also face away from the vent outlet.
d. Use vent pipe manufacturer’s vent cap or exit cone (velocity cone), fire stop, support collar, roof
flushing and storm collar.
e. AERCO recommends the use of an exit cone in lieu of a termination rain cap for normal
installations and T- termination and H-termination for high-wind areas.
