On August 1, 2007, the Technical Standards & Safety Authority (TSSA) adopted new national code requirements regarding the installation of plastic venting systems for gas burning appliances such as water heaters, boilers and furnaces.
This new regulation mandates that any new or replacement appliance installation must be completed with a venting material which is marked and complies with the new standard ULC S636 piping rather than unmarked PVC, CPVC or ABS piping which had previously been used for many years. This new national code requirement applies to every home in Ontario. Accordingly, if you install new or replacement equipment in your home on or after August 1, 2007, at the time that you do so, you may also need to upgrade your venting.
NOTE: There is no requirement to upgrade venting for existing equipment that was installed before August 1, 2007. Meaning, there is no obligation for you to upgrade your venting if you are not replacing or installing new equipment. However, at the time that you choose to replace or install new equipment, you will need to ensure that venting for the new equipment meets the code requirements at that time.
