†ABS plastic does not require a primer before solvent cementing. A cleaner for ABS is recommended to remove any surface
residue. ABS cleaners are not subject to ASTM standards.

Poly Pror
NOTE: Polypropylene vent systems are UL−1738 and ULC S636 listed and assembled using mechanical fastening systems
supplied by the vent manufacturer.
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 vent/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 52 for Direct Vent/2−Pipe system and
Figure 53 for Ventilated
Vent/1−Pipe system. For exterior termination arrangements,
refer to Figure 54 for Direct Vent/2−Pipe system and Figure 55
for Ventilated Combustion Air/Non− Direct/1−Pipe system.
Contact Local code authorities for other requirements to and/or
exemptions from the National codes shown in the figures.
Roof termination is the recommended termination location.
Roof terminations provide better performance against
sustained prevailing winds. The roof location is preferred since
the vent and combustion air system is less susceptible to
damage or contamination. The termination is usually located
away from adjacent structures or other

inside corners, windows, doors or other appliances. It is less
prone to icing conditions, and it often has less visible vent
vapors.
Sidewall terminations may require sealing or shielding of
building surfaces with a corrosive resistance material due to the
corrosive properties of combustion products from the vent
system, as well as protection of adjacent structures.
NOTE: (Direct Vent/2−Pipe system ONLY) A factory accessory
termination kit MUST be used. See Table 11 for available
options.
NOTICE
RECOMMENDED
TERMINATIONS
It is recommended that sidewall vent terminations of over
24 inches (0.6 M) in length or rooftop vent terminations
of over 36 inches (1 M) in vertical length be supported by
EITHER the Direct Vent Termination Kit shown in Table
11 or by field-supplied brackets or supports fastened to
the structure.
