An outdoor condensing furnace is provided with a condensate drain line which passes through the heat exchange compartment and to a location within the building where it can be discharged at temperatures above freezing. During heating operation, the drain line is maintained at temperatures above freezing such that the condensate will not freeze, and if condensate is trapped in the drain line and freezes during periods of nonheating operation, then it will be quickly thawed when heating operation is resumed. In an alternate embodiment, a drain pan is placed in direct contact with the primary heat exchanger and the condensate is routed to drain pan to be vaporized. Another embodiment provides for routing of the condensate from the condensing heat exchanger, through a flue pipe, and to a drain site which is at above freezing ambient conditions.

The apparatus of claim 1, further comprising a plurality of squeegees attached to said squeegee belt. 15. The apparatus of claim 1, wherein said distal portion of said squeegee, when in operative association with said inner surface of said printing belt, travels along a linear path. 16. The apparatus of claim 15, wherein said printing belt travels along a linear path opposing the linear path of said distal portion of said squeegee. 17. The apparatus of claim 16, wherein said linear paths are in a vertical orientation. 18. An apparatus for direct rotary printing a layer of radiation curable material onto a curved surface of individual articles, said apparatus comprising a continuous loop shaped printing belt having an inner surface defining an interior space and an outer surface arranged in a vertical plane, a printing belt drive assembly for rotating said printing belt, a continuous loop shaped squeegee belt arranged within said interior space, a squeegee belt drive assembly for rotating said squeegee belt, said printing belt and said squeegee belt each having a planar portion opposing one another in spaced apart relationship, a source of radiation curable material in communication with said interior space, at least one squeegee attached to said squeegee belt, said squeegee having a distal end in operative association with said source of radiation curable material for transferring said material to said inner surface of said printing belt. 19. The apparatus of claim 18, wherein said source comprises an applicator block having a surface and a plurality of holes for discharging said material onto said surface. 20. The apparatus of claim 18, wherein said printing belt drive assembly comprises a belt drive and a belt follower arranged in spaced apart relationship, and a motor for rotating said belt drive whereby said printing belt is rotated. 21. The apparatus of claim 20, wherein said printing belt is coupled to said belt drive and said belt follower by a timing belt attached to said printing belt. 22. The apparatus of claim 20, further comprising means for fixedly positioning one of said belt drive and said belt follower in a plurality of spaced apart positions with respect to each other. 23. The apparatus of claim 18, wherein said squeegee belt drive assembly comprises a belt drive and a belt follower arranged in spaced apart relationship, and a motor for rotating said belt drive whereby said squeegee belt is rotated. 24. The apparatus of claim 23, wherein said squeegee belt comprises a timing belt. 25. The apparatus of claim 23, further comprising means for fixedly posi
