Carrier Infinity Multipoise Furnace, 95% AFUE, 100,000 BTU, Single-Stage Heating, Variable Speed, Ultra Low Nox (SCAQMD/SJVAPCD/BAAQMD Compliant), 115/1

The 59CU5B Infinity® Ultra-Low NOx gas furnace delivers consumer comfort in a unit that meets California’s South Coast Air Quality Management District (SCAQMD) and San Joaquin Valley Air pollution Control District (SJVAPCD) NOx emissions limit of 14ng/J. Offering the performance and benefits of our Infinity Series gas furnaces, this furnace releases 65% less nitrogen oxides (NOx) than previous models. NOx contributes to the formation of smog and acid rain and the deterioration of water quality. Lower NOx emissions mean lower production of particulate matter and cleaner air for the environment. Energy efficiency is at the heart of this furnace with up to 95.0% AFUE gas efficiency and the electrically-efficient Infinity communicating variable-speed constant airflow ECM blower motor. This gas furnace also features Upflow/Horizontal installation flexibility, and is available in three model sizes. All sizes can be vented for direct vent/two-pipe, ventilated combustion air, or single-pipe applications.

• Communicating Variable speed, Constant airflow (VCA) ECM blower motor for electrically efficient operation all year long in heating, cooling and continuous fan operation.

• Single-stage gas valve with pre-mix burner

• Pilot free, hot surface ignition

• Variable-speed inducer motor for consistent operation

• Supports single-stage, two-stage, and variable speed cooling units

• High temperature limit control designed to prevent overheating

• Adjustable blower speed for heating, cooling, continuous fan, anddehumidification

• Stainless-steel primary heat exchanger
