1 TECHNICAL SPECIFICATIONS FG7S (C and L Series) High Efficiency/Direct Vent or Non Direct Vent Single Stage Condensing Upflow/Horizontal and Downflow Gas Furnaces Induced Draft AFUE Input 38, ,000 Btuh The high efficiency upflow gas furnace may be installed free standing in a utility room, basement, or enclosed in an alcove or closet. Upflow/horizontal units come ready for upflow or horizontal application. The extended flush jacket provides a pleasing appliance appearance. Design certified by CSA for application in Canada and the United States. This furnace series is approved and certified by the SCAQM and the SJVAPC Districts in the state of California under each Districts Mitigation Fee Plan for shipment into and sales in both districts. For California installations in SCAQMD only: This furnace does not meet the SCAQMD Rule 1111 NOx emission limit (14 ng/j), and thus is subject to a mitigation fee of up to $450. This furnace is not eligible for the Clean Air Furnace Rebate Program: FEATURES and BENEFITS 100% fired and tested: All units and each component are tested on the manufacturing line. Best packaging in the industry: Unique corner post design assures product will arrive to the homeowner dent free. 30 second blower delay at start-up assures a warm duct temperature at furnace start-up. Adjustable blower off settings (60, 90, 120 and 180 seconds). 30 second post purge increases life of heat exchanger. Hot surface igniter: Innovative application of a silicon nitride type igniter. Utilizes proven Smartlite technology. Color coded wire harness: Designed to fit the components, all with quick-connect fittings for ease of service and replacement. Flexible category IV venting system: May be vertically or horizontally vented using either a one-pipe or two-pipe system for maximum flexibility in installation. High Static Blowers: All models equipped with high static blowers. Low Boy Height: Easy to apply in low ceiling applications, works well with taller high SEER coils, easier to handle and install. Tubular primary heat exchanger: Heavy gauge aluminized steel heat exchanger and stainless steel secondary heat exchanger assures a long life. 90 second fixed cooling cycle blower-off delay (TDR) increases cooling performance when matched with a Nortek Global HVAC coil. High efficiency blower kits maximize efficiencies. On select units, a SEER improvement of up to 1 point is realized. Multi-speed direct drive blower: Designed to give a wide range of cooling capacities. Switches on PCB, provide ultra easy motor speed selection. LP convertible: Simple burner orifice and regulator spring change for ease of convertibility. Diagnostic lights for easy troubleshooting without counting flashes: Dedicated light for flame signal strength and 2 lights in combination to indicate all other fault codes with easy to recognize states without counting flashes. Incorporates integrated control board with connections for electronic air cleaner, humidifier, and twinning. Two piece door design enhances furnace appearance and uses captured screws to prevent losing door screws. Blower Compartment: Sealed door to reduce air leakage and insulated for ultra quiet operation. Sealed Vestibule reduces burner and inducer sound levels. Furnace Air Leakage: These furnaces comply with Energy Star cabinet air leakage requirement of less than or equal to 2%. Keep the conditioned air flowing to where it's needed. PolyPro by DuraVent: These furnaces have been tested with and are approved to be installed with DuraVent's PolyPro venting system.

Subtract 2.5 ft. for each additional 2" elbow and 3.5 ft. for each additional 3" elbow. 2. 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. Only the listed pipe materials are approved for use with FG7 Condensing Furnaces. 6
