Trane

Footprint (in inches): 40 (h) by 18 to 25 (w) by 29 (d)

Serviceability features: Integrated furnace control monitors system status and has self-diagnostic capability with stored diagnostics. The last four faults are stored in the control's memory and can be recalled by the servicer. "LitePort" technology provides access to advanced diagnostic and historical information via the use of a handheld PDA or laptop computer. The CFM LED on the integrated furnace control provides visual confirmation of the selected heating and cooling airflows. All components and controls are positioned for easy installation, access, and service.

Technical support: All Trane distributors have a dedicated field service representative who provides local technical support and training.

Noise-reduction features: The "Soft Start" variable-speed blower motor keeps the audible startup noise to a minimum. Overall operating sound level remains extremely low during first-stage operation due to the louverless furnace doors, sealed combustion chamber, reduced firing rate, and lower operating speeds of the induced draft and variable-speed blower motors. The fully insulated furnace cabinet minimizes operating noise. Automotive-grade gaskets on the blower compartment doors reduce the infiltration of unconditioned air.

IAQ features: The XV90 furnace is factory wired for optional humidifiers and electronic air cleaners. Field connection leads are labeled for easy identification. The factory supplied spring-loaded filter rack can be used in both bottom or side return air applications and accepts standard-sized filters, which can be purchased locally.

Thermostat compatibility: Manufacturer did not specify.

Replacement parts compatibility: Manufacturer did not specify.

Additional features: The hinged blower door and dual quarter-turn latches provide access to the blower compartment and help eliminate callbacks to reinstall the furnace doors, the company says. New variable-speed induction motor (VSIM) technology has taken reliability and performance to another level. The XV90 integrated furnace control utilizes the rugged and durable silicon nitride hot surface igniter with adaptive heat up. This increases the life of the igniter by constantly monitoring and adjusting the voltage to the igniter, ensuring that it does not overheat, the company says.

Warranty information: Five-year limited parts, limited lifetime heat exchanger. Extended warranties available.

Special installation requirements: Vent lengths of up to 200 feet are possible due to the use of a variable-speed draft inducer, which also allows the intake and exhaust vents to be terminated in different pressure zones. A low-profile sidewall vent accessory is available to complete the job which is both easy to install and aesthetically pleasing.
