The 58DLA/DLX 4-way Multipoise Gas Furnaces offer deluxe features not found in other single-stage
80% gas furnaces. Carrier's QuietTech™ noise reduction system makes the Comfort 80 an incredibly quiet
induced draft gas furnace. The exclusive Carrier Media Cabinet provides an economic way to add high
performance air filtration to homes. The Comfort 80 control system provides a dehumidification mode, a third
motor speed selection for continuous fan operation selectable at the thermostat, and fault code storage in
the event of power outages. Applications are easy with 4-way multipoise design, through-the-furnace
downflow venting, 13 different venting options, and a door designed for easy service access. An inner
blower door is provided for tighter sealing in sensitive applications. The 58DLA/DLX furnaces are approved
for use with natural or propane gas, and the 58DLX is also approved for use in Low NOx Air Quality
Management Districts.
