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.

Abstract: A multi-position furnace is provided that can be positioned for downflow operation, upflow operation, left horizontal flow operation, or right horizontal flow operation without major modifications in the field. The furnace includes a multi-position condensate draining system which facilitates draining of condensate fluid regardless of the orientation of the furnace. The condensate draining system includes a header box and an exhaust manifold, each of which includes a number of drain ports that allow fluid condensing from combustion gasses to be drained regardless of furnace orientation. A trap is configured for attachment to the furnace in any one of four different positions, and receives condensate fluid from the header box and from the exhaust manifold. An air intake manifold is specially configured to maintain a low profile, thereby facilitating use of the multi-position condensate draining system.
