EX. 4 –
Example 4 shows the vent exiting one side of the house while the inlet
air is on the opposite side of the structure. Here the vent pipe length
must be within the allowable length for the size of Furnace and size of
the vent pipe. This example demonstrates that the pipes do not have
to exit on the same side of the structure.
Attaching Vent Piping
VENT FITTING MATERIAL – PLASTIC
Gas and liquid tight single wall vent fittings, designed for resistance to corrosive flue condensate, MUST be used throughout.
Listed in the Approved Vent Pipe Materials table are designations for different types of 2" and 3" size pipe and fittings that meet these
requirements. The materials listed are various grades of PVC, CPVC, ABS, PolyPro® by DuraVent , Z-Dens by Novaflex Group, Innoflue® by
Centrotherm, ECCO™ polypropylene venting system, and PolyFlue™ polypropylene venting systems.
ATTACHING VENT PIPING
Important: Products installed in Canada must use vent systems that are certified to the Standard for Type BH Gas Venting Systems (ULC
S636) for Class II-A venting systems (up to 65°C). Components of the vent system must not be interchanged with other vent
systems or unlisted pipe or fittings. Plastic components, specified primers, and glues must be from a single system manufacturer
and not intermixed with other system manufacturer's vent system parts. In addition, the first three feet of the vent pipe must be
visible for inspection.
PIPE JOINTS: All joints must be fastened and sealed per manufacturer instructions and local and national codes to prevent escape of
combustion products into the building.
