Performance and Efficiency

The ACiQ N80MSN0451412A operates with a 44,000 BTU input and an 80% AFUE rating, resulting in a heating output of 35,200 BTU. This means that 80% of the fuel consumed is converted into usable heat for your home, while the remaining 20% is lost through flue venting and normal operation. As with all 80% AFUE furnaces, this unit requires metal flue venting. If PVC venting is needed, a furnace with a 90% or higher efficiency rating is required.

This furnace is configured for natural gas operation but can be converted to propane with the purchase of an optional LP kit. Please note that this model is not Low NOx or Ultra Low NOx compliant, and shipments to California may incur a mitigation fee.

Warranty

ACiQ provides a limited 10-year parts warranty and a 20-year heat exchanger warranty. To maintain warranty coverage, the furnace must be registered with the manufacturer within 90 days of installation, and installation must comply with all applicable state and local codes.

Installation and Durability

Designed for installation flexibility, the ACiQ N80MSN0451412A can be installed in upflow, downflow, or horizontal configurations, making it suitable for a wide range of applications. Its durable outer cabinet is built to withstand long-term wear, ensuring reliable performance and year-round comfort. Please note that this furnace is not approved for standalone mobile home installation.
