Why the N9MSE0801716A Stands Out in the Crowded HVAC Market
Not all gas furnaces are created equal. The N9MSE0801716A brings several advantages that make it worth your consideration:
Exceptional Efficiency for Lower Energy Bills
With a 95.5% AFUE rating, this furnace converts nearly all your fuel dollars into actual heat. That’s huge compared to older furnaces that might operate at 70-80% efficiency. For every dollar you spend on fuel, about 96 cents goes toward heating your home rather than escaping up the flue.
Over the lifetime of the furnace, this efficiency can translate to thousands in savings. The initial investment in the N9MSE0801716A pays dividends every heating season.
Installation Flexibility Makes It Perfect for Any Home
One of the biggest headaches with furnace replacement is finding a unit that fits your existing setup. The N9MSE0801716A eliminates this concern with its multi-positional design. Whether you need upflow, downflow, or horizontal installation (left or right), this furnace adapts to your space, not the other way around.
At just 35 inches tall, it also fits into tight spaces where other furnaces might not, making it ideal for closets, attics, and basements.
Built for Reliability and Long-Term Performance
The N9MSE0801716A doesn’t cut corners on build quality. The RPJ primary heat exchanger and stainless steel secondary heat exchanger are designed for durability and efficient heat transfer. The high-quality, corrosion-resistant cabinet protects the internal components for years of reliable operation.

Smart Features of the N9MSE0801716A That Make Life Easier
Beyond the basics, this furnace includes thoughtful features that enhance performance and make maintenance simpler:
Self-Diagnostics with LED Indicator
Nobody wants to play guessing games when issues arise. The N9MSE0801716A includes a self-diagnostic system with a bright LED that helps quickly identify potential problems. This feature saves time and money on service calls by pinpointing issues for technicians.
Versatile Venting Options
This furnace supports at least twelve different venting configurations, including direct vent, single-pipe venting, or ventilated combustion air. This flexibility makes installation possible in virtually any home, regardless of existing ductwork or venting limitations.
Easy Maintenance Design
The slide-out heat exchanger and blower assembly make routine maintenance and service significantly easier. The easy door removal system provides quick access to internal components without complicated disassembly procedures.
Pre-installed Internal Condensate Drain System
High-efficiency furnaces produce condensate that needs proper drainage. The N9MSE0801716A comes with a pre-installed internal condensate drain system, simplifying installation and preventing potential water damage issues.
Is the N9MSE0801716A the Right Size for Your Home?
At 80,000 BTU, this furnace hits a sweet spot for many homes. It’s powerful enough to heat medium-sized homes efficiently while avoiding the excess capacity (and cost) of larger units.
As a rule of thumb, homes in moderate climates typically need 30-40 BTU per square foot. This means the N9MSE0801716A is generally suitable for homes between 2,000-2,600 square feet. However, factors like insulation quality, window efficiency, ceiling height, and local climate all affect the appropriate sizing.
Always have a professional HVAC contractor perform a Manual J load calculation to determine the right size for your specific home.
Installation Considerations for the N9MSE0801716A Gas Furnace
While the N9MSE0801716A is designed for easier installation than many competitors, proper installation remains critical for safety and performance:
Professional Installation Requirement
This gas appliance requires a trained technician to install. Improperly connecting gas lines or venting systems can be dangerous or even fatal. Professional installation ensures safety, optimal performance, and maintains warranty coverage.
