On a boiler vent? Is this allowed?

There is a special high temp product for that application.

What is the vent material?

It is a thin wall PVC product, the whole unit was not working, recommending Boiler dude.

Looks like the high temp stuff:

The reason I ask is that if it was ultravent or plexivent there has been a recall on it.

The replacement program is over at the end of this month if I remember correctly.

Found it

Deadline approaching

Wonderful, Thank you Larry and Michael. I will inform the client.
