What's included

 

For an affordable, efficient, and long lasting solution for heating your home, choose a 120K BTU 95% AFUE Multi Speed Trane RunTru Gas Furnace - Downflow - 24.5inch Cabinet. This downflow furnace creates and distributes warmed air throughout your home to keep your family comfortable when temperatures begin to drop.

This Trane RunTru gas furnace model features a 120,000 BTU capacity, 5 ton nominal air flow, and a 95% annual fuel utilization efficiency (AFUE). This appliance features multiport, inshot burners that operate smoothly and reliably to make sure your family is comfortable while it quietly works in the background.

The American Gas Association has certified this 120K BTU 95% AFUE Multi Speed Trane RunTru Gas Furnace - Downflow - 24.5inch Cabinet for use with natural or liquefied petroleum (LP) gas. When the gas furnace arrives on your doorstep the unit is ready for a natural gas installation. If you need a system that runs off LP gas, you can purchase a separate conversion kit to easily switch the fuel type compatibility.

This particular Trane RunTru gas furnace measures 34 high, 24.5 wide, and 28.75 deep, so it can be installed out of the way in a tight area like a closet or basement. The furnace's dimensions are standard for heating and cooling equipment, so it is compatible with larger, high-efficiency coils and other common accessories.

120K BTU 95% AFUE Multi Speed Trane RunTru Gas Furnace - Downflow - 24.5inch Cabinets are designed with safety, efficiency, and affordability in mind. The following components work together to keep you comfortable when cooler weather begins to roll in.

ECM Motor: This Trane RunTru gas furnace runs off an efficient constant torque blower motor (ECM) that has nine speed options. This ECM motor creates plenty of airflow for most home configurations, and the motor can easily switch speeds on demand.

Hot Surface Ignition System: Instead of a traditional pilot light that burns all the time, this gas furnace uses a silicon nitride hot surface ignition system that heats up when needed. This modern ignition system means you won't have to check and light the pilot each season.

Heat Exchangers: Both of the primary and secondary heat exchangers in a Trane RunTru gas furnace are made from cycle tested, heavy gauge tubular stainless steel that deliver quick heat transfer. The stainless steel material is durable and resists corrosion.

Vortica II Blower: This exclusive blower is designed only for Trane RunTrue gas furnaces. The blower discharges gas fumes outdoors and improves airflow efficiency. Plus, it is easily removed for cleaning when needed.

This Trane RunTru gas furnace includes an integrated system control that allows you to easily maintain and manage your system. The control unit is a solid state device that continuously monitors for the presence of a flame, keeping your home safe.

The control unit's operational program gives you the ability to monitor its many functions including limit sensors, blowers, and the gas valve. The digital display also shows helpful diagnostics for easy troubleshooting when necessary.

Another safety measure within this gas furnace is the dual solenoid combination gas valve and regulator.

The heavy gauge steel casing provides extra strength and protection for your unit. The steel wraparound cabinet is coated with a tough and attractive baked-on enamel finish. No matter your installation setup, the casing features two venting options, and does so without requiring knockouts. This specific 120K BTU 95% AFUE Multi Speed Trane RunTru Gas Furnace - Downflow - 24.5inch Cabinet is assembled at a manufacturing plant in Trenton, New Jersey.
