This contractor made a decision to run the ProForm™ liner directly into the smoke pipe to eliminate the need for a T connection. We were able to accommodate the request due to the access port on the side of the smoke pipe which allowed us to attach the bottom steam fitting. After the liner was cured, the ProForm™ liner was cut inside the smoke pipe forming a seamless transition from smoke pipe to flue. By the way, that flue was 8″ x 24″ and had no issues transitioning into a round pipe.
