Re: Friday's Question
You read correct. Type G copper tube.
CSA B149.1, Natural Gas & Propane Installation Code, is the model code used by provincial regulatory authorities in Canada. The 2000 edition contains important changes on the Types of copper tube to be used in natural gas systems. The B149 Code Update provides the latest information on Type G/GAS tube. Local authorities should be consulted before specifying or installing any Type of copper tube.
