Cellular Core Plastic Vent Material Notification

Cellular Core Plastic Vent Material Notification
Date: March 9, 2016
Cellular Core Plastic Vent Material (Cell-Core)
The residential water heater certification and safety Standard ANSI Z21.10.1-2014/CSA 4.12014 has been modified as it relates to the use of certain plastic venting materials. This new
Standard will go into effect starting in April 2016. The revised standard will “Prohibit” the use
of “Cellular Core” plastic venting material in any residential non-metallic water heater venting
This will affect all of our residential power vented products that use plastic vent material to
exhaust flue gases to the outside of the building. This new regulation will apply to new
applications as well as replacement installations.
The Cellular Core material has been removed for our installation manuals as an option, as
well as the Cell-core ASTM numbers. Please follow the installation manual instructions
supplied with the water heater for complete venting system requirements and available
materials allowed.
If you have any questions or concerns please feel free to contact me.
