Feature	Benefit
80% AFUE	By placing more heat in your home and less heat up the chimney, this furnace will save you money on your gas bill compared to older, less efficient models.
Multi-Position	This furnace is convertible to operate in upflow or horizontal positions (the GDT is dedicated for downflow only) giving you and your Goodman Dealer more flexibility in the installation of this unit.
Sound-Isolated Multi-Speed Blower	The GMT/GDT blower is sound-isolated which contributes to making the furnace quiet as it does its job of providing indoor air comfort for your home.  The energy saving multi-speed direct drive motor will also allow your Goodman Dealer to adjust your comfort system's airflow to match your home.  What this means to you is QUIET COMFORT.
Aluminized Tubular Heat Exchanger	This is the heart of your furnace, it separates heat from the products of gas combustion to safely and comfortably heat your home.  Goodman uses a proven design made from durable materials that are so tough it is backed by a 20 YEAR WARRANTY.  You can rest assured that safety and reliability will not be a concern for you when you own a Goodman GMT/GDT furnace.
Bottom or Side Return Air Inlet, Left or Right Hand Gas Service Connection, Removable Solid Bottom Base	These features combine to make the Goodman GMT furnace "multi-position" allowing great flexibility in installations.  Talk to your Goodman Dealer about installation options that may work in your home.
Aluminized Steel Inshot Burners	These burners are reliable, quiet, and efficient.  They provide not only peace of mind, but also contribute to lowering your utility bill.
Integrated Furnace Control Board with Diagnostics	This is the brain of your furnace.  It makes multiple safety checks before lighting the burners every time your thermostat calls for heat.  In the unlikely event that a problem should occur, it directs your Goodmand Service Technician to the problem with trouble codes making repairs faster and less costly.
Hot Surface Ignition System	This ignition system is reliable, quiet, and safe.  It also replaces the old fuel wasting pilot light found on less advanced and older furnaces.
Exclusive Warranty:  20 Year / 5 Year	The GMT/GDT is engineered for reliability and durability, thus the heat exchanger is backed by a 20 Year Warranty. But it doesn't stop there… the balance of all the GMT/GDT parts are warranted for 5 years.  Also, ask about GoodCare Labor Warranties for complete worry free support.
