Features and Benefits
· PlusOne® Diagnostics: Industry-first, 7-segment LED for quick & easy service
· PlusOne® Ignition System: Proven Direct Spark Ignition (DSI) for reliability and longevity
· Low Profile, 34-inch Cabinet: Makes our furnaces ideal for space-constrained installations
· Hemmed Cabinet & Door Edges and Quarter-Turn Door Fasteners (Upflow/Horizontal only): Allows for safe, toolless access and serviceability
· Removable Heat Exchanger: Built with a primary aluminized steel and secondary stainless steel construction, provides maximum corrosion resistance, thermal fatigue reliability and improved serviceability

Features and Benefits R801T UH
· Pre-Marked Hoses: Offers easier identification and installation
· Blower Shelf Design: Ensures serviceability in all furnace orientations
· Replaceable Collector Box: Enables replacement of only the collector box, and doesn’t require replacement of the heat exchanger
· Venting with 2 or 3-inch PVC: Offers options that can be used on all furnace heating input sizes
· Self-Priming Condensate Trap: Allows for on-going water saturation within the trap to keep it primed, and eliminates the need for seasonal service on the condensate trap
