Maytag Nordyne M1200 Series PGF1RA Series with Variable Speed Blower Furnace Stainless Steel
Model PGF1RA Series
with Variable Speed Blower
High Effi ciency / Upfl ow/Horizontal Gas Furnace
Induced Draft - 80+ AFUE
M1200 Product Line
The heart of the PGF1 series furnace with variable speed blower is the ECM
motor (electronically commutated motor). The ECM consists of a brushless
DC type motor with a microprocessor based variable speed drive. The drive
continuously monitors RPM and torque output of the motor. This information
is fed into pre-programmed algorithms in the microprocessor for correct motor
output to maintain constant airfl ow regardless of external static pressure.
The microprocessor stores delay profi les to optimize the effi ciency and
performance of the split system. The variable speed blower steps through
intermediate airfl ows during the on and off profi les. This results in smoother,
more effi cient operation with quiet, gradual starts and stops. The furnace is
design certifi ed by CSA International (Canadian Standards Association).
Features and Benefi ts
• 100% fi red and tested — All units and each component (both mechanical
and electrical) are tested on the manufacturing line.
• Best packaging in the industry — Unique design assures product will
arrive to the homeowner dent free.
• Clean and quiet operation — Due to the unique design of in-shot burners,
location of inducer, return air vents, and use of insulation.
• Fixed 30 second blower delay at burner start-up assures a warm duct
temperature at furnace start-up.
• Fixed 30 second post purge increases life of heat exchanger.
• SmartStartTM Control Board — Provides extended life to ignitors in
furnaces using hot surface ignition technology. Programmed to learn the
heat-up characteristics of the ignitor, then adapt the ignition time to the
characteristics of the furnace so the ignitor is energized appropriately.
• Dependable, hot surface ignitor — Innovative application of an appliance
type ignitor with a 20 year history of reliability.
• Color coded wire harness — Designed to fi t the components, all with
quick-connect fi ttings for ease of service and replacement.
• Approved for categories I and III venting systems — May be common,
dedicated, or horizontal vented for maximum fl exibility in installation.
• Tubular primary heat exchanger — Heavy gauge aluminized steel heat
exchanger assures a long life.
• Fixed cooling cycle blower-off delay (TDR) increases cooling performance
when matched with a Maytag coil.
• Fully insulated blower cabinet for quiet operation.
• Variable speed blower included to maximize air conditioner and heat
pump effi ciencies. On selected units, SEER ratings up to 14 and HSPF
ratings up to 8.5 are ARI listed.
• LP convertible — Simple burner orifi ce and regulator spring change for
ease of convertibility.
• Diagnostic lights fl ash to identify limit failure, pressure switch failure,
improper ground and polarization, and low fl ame signal — for easy
troubleshooting.
• Incorporates integrated control board with connections for electronic
air cleaner, humidifi er and twinning.
• Two piece door design enhances furnace appearance and uses screw
fasteners for easier accessibility.
• 3 amp fuse protection against low voltage shorts; protects transformer
and control board.
• Low voltage terminal board for easy fi eld wiring.
• Components and Controls — Designing quality into our products means
selecting manufacturers that have a reputation for delivering high quality,
dependable products
