The SL280NV Ultra Low NOx gas furnace is the first in Lennox’s new line of eco-efficient furnaces, which are the first to meet new low-emission regulations in certain California markets. The unit produces 65% lower NOx emissions than standard low NOx furnaces, according to the firm. A variable-speed blower motor and two-stage gas valve allows the furnace to adjust airflow and heating output to help maintain an ideal temperature throughout the home.
