The Shieldmaster 135 Degree Tee Piece is utilized when the flue passes through any external wall at 45°, and it takes the run back upto vertical. The benefit of using this 'Long' version as opposed to the standard Tee Piece, is that it negates the need to use an adjustable length (travelling through the wall) and eliminates the joining of the adjustable length to the standard Tee piece.
This part allows for very easy draining & sweeping of the external system. It’s important to note that this component will need a Tee Cap. You won’t require any additional sealants or silicone to seal all the joints. It has a unique push-fit locking system to make connection and disconnection very simple. The quoted diameter is the internal diameter and the surrounding insulation makes it 2” larger.
