Enjoy heat that is safe, reliable and efficient with the Napoleon NPX100S5A 100,000 BTU natural gas furnace featuring an ultra-efficient ECM-X13 motor. This motor uses about 80% less electrical consumption than conventional blower motors. On continuous fan speed it uses about 60 to 80 watts compared to 400 watts used by a conventional motor. The Napoleon NPX100S5A gives more comfort for every dollar spent.

This unit is very efficient with a 95% Annual Fuel Utilization Efficiency (AFUE). However, it's still very small and powerful standing at 32 7/8" tall with 100,000 BTUs. This is one of the smallest high efficiency furnaces on the market.

Using it is Easy
The Napoleon gas furnace features a self diagnostic integrated furnace control (IFC) that contains LED service indicator lights allowing for quick and efficient service calls. It can also easily accommodate hook-ups for a humidifier, HRV, and electronic air cleaner.

Operates Quietly
This model has been specifically designed with low noise in mind. The blower compartment has been acoustically insulated so operation is whisper quiet not disturbing you and your family. It's also very durable with a powder coated finish to resist scratches and corrosion.

Versatile Installation
Enjoy ease of installation with the Napoleon NPX100S5A single stage furnace. You can install it four different ways depending on your need: upflow, downflow, and horizontal left or right. Also, zero clearance is required so easily place one out of the way in a closet or alcove.
