An installation with a double wall Tee connection is an installation that goes horizontally through a wall then turns up vertically. This is made possible with the use of the following parts of a double wall chimney.
To be able to transition from the single wall black stove pipe from the stove into the Class A chimney double wall pipe you need a Stove Pipe Adaptor. This adapter will not only give you a transition to single wall it also gives the double wall pipe a nice clean finish look.
Then the double wall pipe passes through a wall firestop. The horizontal double wall chimney pipe then locks into the Tee.
This Tee is supported by a Tee Support. Then on top of the double wall tee, you can install lengths of the factory built chimney to the required height. The lengths of the Class A chimney pipe will need wall straps securing the double wall pipe to the house.
Once the Class A chimney double wall pipe extends above the roof you may need to use a roof brace. This secures the factory built chimney to the roof. Then to finish off the Class A Chimney installation with a tee, you need to install one type of Class A rain caps on top of the factory built chimney.
