Nortek Global HVAC, a leading manufacturer of indoor air comfort products, has added the premium SD Series, a 95-percent AFUE, ultra-low NOx residential furnace that offers the industry’s easiest installation/service features.
The single-stage, upflow/horizontal, natural gas-fired furnaces are available from Nortek Global HVAC’s Frigidaire® (FG8SD) and Maytag® (MGC3SD) brands. Both models meet all U.S. ultra-low NOx 14-nanograms/joule emission standards including the South Coast Air Quality Management District (SCAQMD) and San Joaquin Valley Air Pollution Control District (SJVAPCD) certifications under California Rule 1111 and Rule 4905, respectively.
Each brand’s two models range in thermal input from 50,000 to 100,000-Btuh and feature a solid 22-ga., high finish cabinet with a low-boy 35-inch height, 28-inch depth and widths of 14 and 21-inches that fit most retrofit and new construction furnace spaces. A 70,000-Btuh model will follow the initial launch.
All models are tested to ASHRAE Standard 193 for “Airtightness of HVAC Equipment.” They’re also Energy Star-approved with nine-speed, constant torque EC motor blowers, cabinet leakage compliance at well under 2.0-percent, and the 95-percent AFUE.
Each unit is 100-percent fired and checked with more than 100 manufacturing line test procedures.
The FG8SD and MGC3SD both feature an easily replaceable printed circuit board (PCB) that’s accessible after removing only the cabinet’s front cover. Ease-of-service additions are a color-coded wire harness with quick-connect fittings and the cabinet’s captured screws that can’t get lost.
Installation ease includes gas pipe connections that are accessible from both right and left sides; and a side-discharge capable flue connection.
Other benefits of the FG8SD and MGC3SD are:
