Service FactsSEQUENCE OF OPERATION

Thermostat call for heat (2-stage thermostat)Call for 1st stage only:W1 thermostat contacts close signaling the control module torun its self-check routine. After the control module hasverified that the 1st stage pressure switch contacts are openand the limit switch(es) contacts are closed, the draft blowerwill be energized.

As the induced draft blower comes up to speed, the pressureswitch contacts will close and the ignitor warm-up period willbegin. The ignitor will heat for approx. 20 seconds, then thegas valve is energized in 1st stage to permit gas flow to theburners.

The flame sensor confirms that ignition has been achievedwithin the 4 second ignition trial period.

As the flame sensor confirms that ignition has been achieved,the delay to fan ON period begins timing and after approx.45 seconds the indoor blower motor will be energized at lowspeed and will continue to run during the heating cycle.

Call for 2nd stage after 1st stage:W2 thermostat contacts close signaling a call for 2nd stageheat. After a 30 second delay, the induced draft blower willbe energized on high speed and the 2nd stage pressure switchcontacts will close. The gas valve is energized in 2nd stageand the indoor blower motor in high speed.

2nd stage satisfied, 1st stage still called:W2 thermostat contacts open signaling that 2nd stageheating requirements are satisfied.

The induced draft blower is reduced to low speed allowing the2nd stage pressure switch contacts to open and the gas valveis reduced to 1st stage. The indoor blower motor is reduced tolow speed.

1st stage satisfied:W1 thermostat contacts open signaling that 1st stage heatingrequirements are satisfied. The gas valve will close and theinduced draft blower will be de-energized. The indoor blowermotor will continue to run for the fan off period (Fieldselectable at 60, 100, 140 or 180 seconds), then will be de-energized by the control module.

Thermostat call for heat (1-stage thermostat)W1/W2 (jumpered) thermostat contacts close signaling a callfor heat. 1st stage sequence of operation remains the same asabove. 2nd stage heat will energize after the stage delaytimer (field selectable at .5, 5, 10 or 15 minutes) has expired.

Thermostat satisfied:W1/W2 (jumpered) contacts open signaling the controlmodule to close the gas valve. The induced draft blower isswitched to low speed and de-energized after the post purgetimer has expired. The indoor blower motor will continue tooperate after the flames are extinguished and then isswitched to low heat speed for the FAN-OFF period.

WARNING!Should overheating occur, or the gas supply fail to shut off,shut off the gas valve to the unit before shutting off theelectrical supply. Failure to follow this warning could resultin property damage, personal injury, or death.

Indoor blower operation with thermostat fan switch “ON”:Fan is R-G.R-W energized, fan continues to run without interruption.Heat Low speed if it is a two stage furnace.Heat speed if it is a single stage furnace.

INDOOR BLOWER TIMINGHeating: The integrated furnace control module controlsthe indoor blower. The blower start is fixed at 45 secondsafter ignition. The FAN-OFF period is field selectable bydip switches SW-2, #1 and #2 at 60, 100, 140, or 180seconds. The factory setting is 100 seconds.

W1-W2 stage delay (jumpered together) is field selectable bydip switch SW-1, #1 and #2 at .5, 5, 10 or 15 minutes. Thefactory setting is 10 minutes. (See wiring diagram).

Cooling: The fan delay-off period is set by dip switches onthe Integrated Furnace Control. The options for coolingdelay off is field selectable by dip switches #5 and #6.

The following table and graph explain the delay-off settings:

Service FactsPERIODIC SERVICING REQUIREMENTS

WARNING!Disconnect power to the unit before removing the blowerdoor. Allow a minimum of 10 seconds for IFC power supplyto drain to 0 volts. Failure to follow this warning couldresult in property damage, personal injury or death.

WARNING!CARBON MONOXIDE POISONING HAZARD

Failure to follow the service and/or periodic maintenanceinstructions for the furnace and venting system, couldresult in carbon monoxide poisoning or death.

1. GENERAL INSPECTION – Examine the furnaceinstallation annually for the following items:a. All flue product carrying areas external to the furnace

(i.e. chimney, vent connector) are clear and free ofobstruction. A vent screen in the end of the vent (flue)pipe must be inspected for blockage annually.

b. The vent connector is in place, slopes upward and isphysically sound without holes or excessive corrosion.

c. The return air duct connection(s) is physically sound,is sealed to the furnace and terminates outside thespace containing the furnace.

d. The physical support of the furnace should be soundwithout sagging, cracks, gaps, etc., around the base soas to provide a seal between the support and the base.

e. There are no obvious signs of deterioration of the furnace.

2. FILTERS – Filters should be cleaned or replaced (withhigh velocity filters only), monthly and more frequentlyduring high use times of the year such as midsummeror midwinter.

3. BLOWERS – The blower size and speed determine theair volume delivered by the furnace. The blower motorbearings are factory lubricated and under normaloperating conditions do not require servicing. If motorlubrication is required it should only be done by aqualified servicer. Annual cleaning of the blower wheeland housing is recommended for maximum air output,and this must be performed only by a qualified serviceror service agency.

4. IGNITER – This unit has a special hot surface directignition device that automatically lights the burners.Please note that it is very fragile and should be handledwith care.

CAUTION!Do not touch igniter. It is extremely hot.

5. BURNER – Gas burners do not normally requirescheduled servicing, however, accumulation of foreignmaterial may cause a yellowing flame or delayed igni-tion. Either condition indicates that a service call isrequired. For best operation, burners must be cleanedannually using brushes and vacuum cleaner.

Turn off gas and electric power supply. To clean burners,remove burner box cover (6 to 8 screws) and top burnerbracket. Lift burners from orifices.

NOTE:Be careful not to break igniter when removing burners.

Clean burners with brush and/or vacuum cleaner. Re-assemble parts by reversal of the above procedure. Theburner box must be resealed when replacing box cover.

NOTE:On LP (propane) units, some light yellow tipping of theouter mantle is normal. Inner mantle should be bright blue.

Natural gas units should not have any yellow tipped flames.This condition indicates that a service call is required. Forbest operation, burners must be cleaned annually usingbrushes and vacuum cleaner.

NOTE:On LP (propane) units, due to variations in BTU contentand altitude, servicing may be required at shorter intervals.

WARNING!CARBON MONOXIDE POISONING HAZARDFailure to follow the service and/or periodic maintenanceinstructions for the furnace and venting system, couldresult in carbon monoxide poisoning or death.

6. HEAT EXCHANGER/FLUE PIPE – These items must beinspected for signs of corrosion, and/or deterioration at thebeginning of each heating season by a qualified servicetechnician and cleaned annually for best operation. Toclean flue gas passages, follow recommendations below:

a. Turn off gas and electric power supply.

b. Inspect flue pipe exterior for cracks, leaks, holes orleaky joints. Some discoloration of PVC pipe is normal.

c. Remove burner compartment door from furnace.

d. Inspect around insulation covering flue collector box.Inspect induced draft blower connections fromrecuperative cell and to the flue pipe connection.

e. Remove burners. (See 4.)

f. Use a mirror and flashlight to inspect interior of heatexchanger, be careful not to damage the igniter, flamesensor or other components.

g. If any corrosion is present, contact a service agency.Heat exchanger should be cleaned by a qualifiedservice technician.

h. After inspection is complete replace burner box cover,burners, and furnace door.

i. Restore gas supply. Check for leaks using a soapsolution. Restore electrical supply. Check unit fornormal operation.

7. COOLING COIL CONDENSATE DRAIN - If a coolingcoil is installed with the furnace, condensate drainsshould be checked and cleaned periodically to assurethat condensate can drain freely from coil to drain. Ifcondensate cannot drain freely water damage couldoccur. (See Condensate Drain in Installer’s Guide.)

CAUTION!Label all wires prior to disconnection when servicingcontrols. Wiring errors can cause improper anddangerous operation.

Verify proper operation after servicing.

WARNING!NEVER USE AN OPEN FLAME TO TEST FOR GAS LEAKS:AN EXPLOSION COULD OCCUR, CAUSING INJURY ORDEATH.

INTEGRATED FURNACE CONTROLGREEN "STATUS" LED FLASH CODES

Flashing Slow --- Normal - No call for Heat

Flashing Fast --- Normal - Call for Heat

Fault Code ResetThe last 4 fault codes can be erased from memory by power-ing up the control with “G” energized and then applying “R”to the “W1” terminal 3 times within 6 seconds. The controlwill acknowledge the reset by turning on the red LED for2 seconds.

FAULT CODE RECOVERYOn power up, last 4 faults, if any, will be flashed on the redLED. The newest fault detected will flash first and the oldestlast. There will be a 2 second delay between fault codeflashes. Solid red LED error codes will not be displayed.

The Green LED will be on solid during last fault recovery.At any other time the control is powered, the Green LEDindicator light will operate as shown in Table 14 and the redLED will flash LitePort data (one flash) every 20 seconds.
