About this product

The MRCOOL® Signature Series Single-Stage 96% AFUE 45k BTU gas furnace is a quiet-running, low NOx, and energy efficient unit that provides superior warmth during the harshest winter weather. With a 96% AFUE, the furnace features a multi-speed high efficiency blower motor and offers enhanced cooling SEER ratings when applied with properly matched cooling equipment. It features a durable build and finish with an aluminized steel primary heat exchanger with crimped non-welded construction. The aluminized steel inshot burners provide smooth ignition with a durable silicon nitride ignitor. Thanks to the single-stage gas valve, you can expect your home to be heated quickly. With a compact 33-inch design, a left or right utility connection, and a zero step horizontal conversion, installation is easy and time-saving. It also features standardized widths for easy coil fit, a removable floor base for bottom return air, and can be easily vented with PVC pipe. The furnace is design certified for direct and non direct applications, and an optional LP kit is available to easily convert the unit to a liquid propane configuration. Maintenance of the unit is easy thanks to the easily removable slide out blower design. MRCOOL® proudly offers a 10-year parts warranty and a lifetime heat exchanger warranty to provide peace of mind.
