BROAN FG7MQ Gas Furnace

IMPORTANT INFORMATION

Fully Modulating, Variable Speed, Condensing Upflow/Horizontal Gas Furnaces Induced Draft – 97.0 AFUE Input 60,000 – 120,000 Btuh
The high efficiency upflow gas furnace may be installed free standinginautility room,basement,orenclosedinanalcove 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.

FEATURES and BENEFITS

SEER: Energy efficient brushless DC (ECM) motor gives up to 1 SEER point efficiency gain in cooling.
Modulating heating operation Includes:
- Modulating gas valve from 100% to 50% input in 5% increments.
- Time proportioning modulation down to 15%.
- Variable speed inducer and blower.
100% fired and tested: All units and each component are tested on the manufacturing line.
Best packaging in the industry: Uniquecornerpostdesign assures product will arrive to the homeowner dent free.
30 second blower delay: At start-up assures a warm duct temperatureatfurnacestart-up.Adjustablebloweroffsettings (60, 90, 120 and 180 seconds).
30 second post purge: Increases life of heat exchanger.
Hot surface igniter: Innovative application of a silicon nitridetype igniter. Utilizes proven Smartlite® technology.
Color coded wire harness: Designedtofitthecomponents, 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: Heavygaugealuminized 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 NORDYNE coil.
LP convertible: Simple burner orifice change for ease of convertibility.
Diagnostic lights for easy troubleshooting without counting flashess: Dedicatedlightfor flamesignal 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 and humidifier.
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: Reducesburnerandinducer soundlevels.
iQ Drive Thermostat: Provides modulation down to 15% and is required for furnace operation.
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.

*NOTES:

Subtract 2.5 ft. for each additional 2 inch long radius elbow, 5 ft. for each additional 2 inch short radius elbow, 3.5 ft. for each additional 3 inch long radius elbow, and 7 ft. for each additional 3 inch short radius elbow. Two 45° elbows are equivalent to one 90° elbow.
Subtract 5ft for each 2” tee and 8ft for each 3” tee.
This table applies for elevations from sea level to 2,000 ft. For higher elevations, decrease pipe lengths by 8% per 1,000 ft of altitude.
The minimum length for 2” or 3” diameter vent pipe is 5 ft.
