FG7S (D And M Series)

TECHNICALSPECIFICATIONSFG7S (D and M Series)High Efficiency, Single StageCondensing, Upflow/Horizontal andDownflow Gas Furnace Models95.0 AFUE38,000 - 120,000 Btuh InputThe high efficiency upflow gas furnace may be installed freestanding in a utility room, basement, or enclosed in an alcoveor closet. Upflow/horizontal units come ready for upflow orhorizontal application. The extended flush jacket provides apleasing “appliance appearance.” Design certified by CSAfor application in Canada and the United States.WARRANTY– 10-year all-parts warranty.– 10 Year Quality Pledge to replace the unit if the heatexchanger fails within the first 10 years of operation,to the original owner.– Consumer product registration required for 10 yearAll Parts Warranty and Quality Pledge within a limitedperiod of time after the installation. See currentwarranty document or visit our consumer web site listedon the back of this document for warranty details.– When registered, this product is upgraded to a limitedlifetime heat exchanger warranty.FEATURES and BENEFITS 100% fired and tested: All units and each componentare tested on the manufacturing line. Best packaging in the industry: Unique corner postdesign assures product will arrive to the homeowner dentfree. 30 second blower delay at start-up assures a warmduct temperature at furnace start-up. Adjustable bloweroff settings (60, 90, 120 and 180 seconds). 30 second post purge increases life of heatexchanger. Hot surface igniter: Innovative application of asilicon nitride type igniter. Utilizes proven Smartlite technology. Color coded wire harness: Designed to fit thecomponents, all with quick-connect fittings for ease ofservice and replacement. Flexible category IV venting system: May be verticallyor horizontally vented using either a one-pipe or two-pipesystem for maximum flexibility in installation. High Static Blowers: All models equipped with highstatic blowers. Low Boy Height: Easy to apply in low ceiling applications,works well with taller high SEER coils, easier to handleand install. Tubular primary heat exchanger: Heavy gaugealuminized steel heat exchanger and stainless steelsecondary heat exchanger assures a long life. 60 second fixed cooling cycle blower-off delay (TDR)increases cooling performance when matched with aNORDYNE coil. High efficiency blower kits maximize efficiencies. Onselect units, a SEER improvement of up to 1 point isrealized. Multi-speed direct drive blower: Designed to give a widerange of cooling capacities. Switches on PCB, provideultra easy motor speed selection. LP convertible: Simple burner orifice and regulator springchange for ease of convertibility. Diagnostic lights for easy troubleshooting withoutcounting flashes: Dedicated light for flame signal strengthand 2 lights in combination to indicate all other fault codeswith easy to recognize states without counting flashes. Incorporates integrated control board with connectionsfor electronic air cleaner and humidifier. Two piece door design enhances furnace appearanceand uses captured screws to prevent losing doorscrews. Blower Compartment: Sealed door to reduce air leakageand insulated for ultra quiet operation. Sealed Vestibule reduces burner and inducer soundlevels.

VENTINGAll models are approved for vertical non direct (1 pipe) and direct (2 pipe) venting applications. See Vent Table below forspecified sizes and allowable lengths.VENT TABLESINGLE PIPE LENGTH (FT.)with 1 long radius 090SM118705060N/A90909090DIRECT VENT,DUEL PIPE LENGTH (ft.)

Two 45 degree elbows are equivalent to one 90 degree elbow.3. One short radius elbow is equivalent to two long radius elbows.4. Do not include termination elbows in calculation of vent length.5. This table is applicable for elevations from sea level to 2000 ft. For higher elevations decrease vent pipe lengths by 8% per 1000 ft. of altitude.6.
