remaining connected to the common venting sys-
tem properly vents when tested as outlined above,
return doors, windows, exhaust fans, fireplace
dampers and other gas burning appliances to their
previous conditions of use.

system should be corrected so that the installation
conforms with the latest edition of the National

est edition of CSA B149 Installation Code for Gas
Burning Appliances and Equipment.
When re-sizing any portion of the common venting

sized to approach the minimum size as
determined using the appropriate tables in
Appendix G in the latest edition of the National
Fuel Gas Code, ANSI Z223.1, in Canada,
