Abstract
A distribution tee assembly 10 for transferring the products of combustion from a heat exchanger 12 to an exhaust vent system 14. The distribution tee assembly 10 includes a distribution tee 16 having an inlet pipe 18 and two transverse outlet pipes 20, 22. A transition region 24 is located proximate a wall of the distribution tee 16. In the transition region there is positioned a deflector vane 28 which diverts incoming combustion products toward the transverse outlet pipes 20, 22. If one of the outlet pipes is capped, all of the combustion products are diverted to the unblocked transverse outlet pipe.
Claims14
A distribution tee assembly for transferring the products of combustion from a heat exchanger to an exhaust vent system, the distribution tee assembly comprising:
- a distribution tee having an inlet pipe and two transverse outlet pipes;
- and
- a transition region including a deflector vane located proximate a wall of the distribution tee for receiving and diverting incoming combustion products to the transverse outlet pipes, the deflector vane guiding the flow of the products of combustion and increasing a vent length capability of the furnace.
A method for configuring a distribution tee assembly for transferring the products of combustion from a heat exchanger to an exhaust vent system, the method comprising the steps of:
- providing a distribution with an inlet pipe and two transverse outlet pipes;
- locating a deflector vane in a transition region positioned proximate a wall of the distribution tee;
- and
- blocking one of the two transverse outlet pipes.
