Locating the Vent Termination
General
NOTE: Termination Requirements for the Provinces of
Alberta and Saskatchewan are located at the end of this
section.
Combustion
−
air inlet pipe (Direct Bent/2
−
Pipe system only) and
vent pipe must terminate outside structure, either through
sidewall or roof.
For vent termination clearance, references to National codes
are shown in
Figure 58
for Direct Vent/2
−
Pipe system and
Figure 59
for Ventilated Combustion Air system. For exterior
termination arrangements, refer to
Figure 58
for Direct
Vent/2
−
Pipe system and
Figure 59
for Ventilated Combustion
Air system. Contact Local code authorities for other
requirements to and/or exemptions from the National codes
shown in the figures.
Roof termination is often preferred since it is less susceptible to
damage or contamination, is usually located away from
adjacent structures, is less prone to icing conditions, and often
has less visible vent vapors. Sidewall terminations may require
sealing or shielding of building surfaces with a corrosive
