Can more than one of these be connected for a longer chimney?
I have a Portuguese wood fired oven with a 6 inch stainless vent will this Duravent pipe fit over or slide inside of my vent pipe?
The Duravent chimney pipes are typically meant to attach to a Duravent anchor plate or combine with other Duravent chimney extensions so not sure if it would work with your existing chimney vent pipe. We do carry chimney extensions that fit the Portuguese Brick ovens from the brand Authentic Pizza Ovens. Click here for the Stainless Steel Chimney
