The Technical Standards and Safety Authority (TSSA) adopted the 2007 supplement to the national Natural Gas and Propane Installation Code (B149.1S1-07) on August 1, 2007. A major change to the code supplement is that all plastic venting will have to be certified to ULC S636.

TSSA understands that there are possible difficulties relating to replacement appliance installations, where it is deemed that the replacement of the entire vent with certified ULC S636 plastic venting is not possible or is impractical due to specifics of that particular installation. To address these installations, TSSA released the Advisory FS-101-07 to indicate the variance conditions for the continued use of existing uncertified plastic vents.

To facilitate the review process and ensure timely response for this variance, ensure that the application is submitted with:
• Fee of $560 per condominium/multi-family dwellings or $150 for single family dwellings;
• Summary of why it is not possible or practical to replace the entire vent;
• Evidence of a satisfactory reasonable visual inspection by a certificate holder; and
• Satisfactory results of the pressure test performed by a certificate holder on the existing venting outlined under condition 5 of Advisory FS-101-07.

The approval of the variance is also subject to the condition that every five years, the vent shall be visually inspected and pressure tested by an appropriate certificate holder in accordance to the terms outlined in the advisory.

Variances approved under Advisory FS-101-07 may be subjected to safety audits by TSSA.
