Mike,



It looks like the plumber ran the tape down the seam of the pipe. The flue should be double wall and there is no seam. For the pilot blowing out, it could the several reasons i.e. (draft, gas valve or the thermocouple) my two cents.

Single wall vent is allowed as long as proper clearances are maintained and they are not passed through a wall, floor or ceiling.

It looks like listed aluminum tape on the duct. I may be wrong.

The pipe looks like “snap-lock” piping normally used for HVAC ductwork. The tape in picture is called “code tape” and it is used to seal up the seams both on flues and HVAC ductboard joints. The red writing is the give away. YOu can buy aluminum foil tape that does not have the writing but most if not all the county inspectors require it to be “code tape”. I am a little curious about using snap’lock ducting for a flue. It will not be double walled like normal flue pipe. Putting tape on flue pipe is not a bad practice. It looks like PVC pipe at the very top too. That would cause me to question the installation as well. The pilot could be getting blown out by downdraft if the flue is not properly installed or as stated earlier a poor thermocouple. Definately would write up for repairs.

Depending on the age of the home some white pipes are actually asbestos piping.
