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.
