8. A horizontal vent terminal must not be installed closer than 3 feet (0.91m) from an inside
corner of an L-shaped structure.
9. A vertical vent must exhaust outside building at least 3 feet (0.91m) above the exit and at least
2 feet (0.61 m) above high point of roof within a 10-foot (3.05 m) radius of termination.
10. A vertical termination less than 10 feet (0.91 m) from a parapet wall must be a minimum of 2
feet (0.61 m) higher than the parapet wall.
7.3 Combining Category IV Vents
To provide a single sidewall or roof penetration that is capable of providing both combustion air
and flue exhaust termination, each Element must be installed using an IPEX System Concentric
Vent Termination Kit. Both the IPEX System PVC and CPVC Flue Gas Venting Systems are third
party tested and listed to the appropriate standard. They comply with the non-metallic vent listing
requirements in CSA B149.1 Natural Gas and Propane Installation Code.
The following IPEX System Concentric Vent Termination Kits are available from Lync:

Table 7
– IPEX System Concentric Vent Termination Kit
Each IPEX System vent kit includes or specifies the required pipe, fittings, hardware, adhesives
and Installation instructions. Follow the IPEX Installation instructions and use only the materials
and adhesives it specifies. Additional copies of the Installation Guide for the IPEX System
concentric vent kit and additional information is available from your local Lync representative.
When using concentric vent termination kits, all combustion air duct, all exhaust vent pipe and the
IPEX concentric vent kit material types must be the same. If the Element is installed with a PVC
exhaust vent pipe, then the combustion air duct and the IPEX concentric vent kit must also be
made of PVC. If the Element is installed with a CPVC exhaust vent pipe, then the combustion air
duct and the IPEX concentric vent kit must also be made of CPVC.
W A R N I N G !
Follow all installation instructions, termination requirements and spacing requirements provided
with listed IPEX Concentric Vent Kit. Use only the pipe, fittings and cement included or
specified in the IPEX installation instructions. Failure to follow the instructions or to use pipe,
fittings or cement not included or specified in the instructions could result in an unreliable vent
assembly and property damage, exposure to hazardous materials, personal injury or death.
