Heating Performance
This furnace puts out about 35,200 BTU once efficiency is factored in. Like all 80% models, it needs metal venting—it can’t use PVC. It ships ready for natural gas but can run on propane with the right kit. California customers may see extra fees due to Low NOx rules.
Warranty
ACiQ includes a 10-year parts warranty and a 20-year heat exchanger warranty when the unit is registered within 90 days. Make sure installation follows local codes to keep coverage active.
Installation Notes
The N80MSN0451412A is easy to place thanks to its multi-position design. The cabinet is sturdy and built for normal residential use. It is not approved for mobile homes without the proper certified kit.
