General Features

COMMUNICATING MODE: Furnace is shipped ready for connection in communicating mode. Requires A/T LINK360A2VVUA Link Smart Thermostat and System Controller (ordered separately).

COMFORT CONTROL: Link communicating technology seamlessly connects system components for advanced diagnostics, performance updates, and optional remote monitoring.

ALTERNATE 24V MODE: Field configurable to 24V non-communicating mode.

NATURAL GAS MODELS: Certified by Intertek for natural and L.P. gas. Limit setting and rating data approved under ANSI standards.

SAFE OPERATION: Integrated System Control (ISC) is a solid-state device monitoring flame presence. Dual solenoid combination gas valve and regulator provide additional safety.

QUICK HEATING: Durable, cycle-tested, heavy gauge aluminized steel heat exchanger for efficient heat transfer. Low energy power vent blower for increased efficiency and fume discharge.

BURNERS: Multiport, Inshot burners for quiet and efficient service. All models convertible to L.P. gas with a conversion kit.

INTEGRATED SYSTEM CONTROL: Operational program controls furnace limit sensors, blowers, gas valve, and flame control with self-diagnostics.

ENERGY EFFICIENT OPERATION: Air-Tite™ cabinet design certified to <1% air leakage per ASHRAE 193.

AIR DELIVERY: Efficient, variable speed blower motor delivers consistent airflow, adjusting for heating or cooling demands.

STYLING: Heavy gauge steel, wrap-around cabinet with baked-on enamel finish. Multiple venting options available.

FEATURES AND GENERAL OPERATION: Silicon Nitride Hot Surface Ignition system eliminates constant pilot. Integrated system control lights main burners upon demand. Complete front service access. Features include low energy power venter and vent proving pressure switches.
