All furnaces meet the latest California seasonal efficiency requirements. 1. Based on 1075 Btu/Ft3. 2. The air flow must be adjusted to obtain a temperature rise within the range shown. 20 Unitary Products Group 170654-YIM-A-1105 GAS PIPING Proper sizing of gas piping depends on the cubic feet per hour of gas flow required, specific gravity of the gas and the length of run. “National Fuel Gas Code” Z223.1 (in U.S.A.) or the current Gas Installation Codes CSAB149.1 (in Canada) should be followed in all cases unless superseded by local codes or gas utility requirements. Refer to the Pipe Sizing Table 5. Two grommets are shipped in the blower compartment (in parts bag taped to the blower housing) of every unit with gas heat and should be used in the knockouts when the gas piping penetrates the front of the unit. After the gas supply piping has been installed, the bottom opening in the unit should be sealed to prevent water from leaking into the building. Gas piping recommendations: The heating value of the gas may differ with locality. The value should be checked with the local gas utility. 1. A drip leg and a ground joint union must be installed in the gas piping. NOTE: There may be a local gas utility requirement specifying a minimum diameter for gas piping. All units require a 1/2” pipe connection at the entrance fitting. 2. When required by local codes, a manual shut-off valve may have to be installed outside of the unit. 3. Use wrought iron or steel pipe for all gas lines. Pipe compound should be applied sparingly to male threads only.

(Based upon a pressure drop of 0.3 inch water column and 0.6 specific gravity gas). GAS CONNECTION The gas supply line can be routed through the knockouts located on the front of the unit or through the opening provided in the unit's base. Refer to Figure 11 to locate these access openings. Typical supply piping arrangements are shown in Figures 4 and 5. All shaded items are field-supplied. If gas supply line is routed through the unit's base ensure that the burner assembly can be removed for maintenance without disturbing the supply line. The supply piping and fittings must lie below the bottom gas manifold to avoid interference with the burner assembly. Unitary Products Group Natural gas may contain some propane. Propane, being an excellent solvent, will quickly dissolve white lead or most standard commercial compounds. Therefore, a special pipe compound must be applied when wrought iron or steel pipe is used. Shellac base compounds such as Gaskolac or Stalastic, and compounds such as Rectorseal #5, Clyde's or John Crane may be used. 4. All piping should be cleaned of dirt and scale by hammering on the outside of the pipe and blowing out the loose dirt and scale. Before initial start-up, be sure that all of the gas lines external to the unit have been purged of air. 5. The gas supply should be a separate line and installed in accordance with all safety codes as prescribed under “Limitations”. After the gas connections have been completed, open the main shut-off valve admitting normal gas pressure to the mains. Check all joints for leaks with soap solution or other material suitable for the purpose. NEVER USE A FLAME. 21 170654-YIM-A-1105 FIRE OR EXPLOSION HAZARD Failure to follow the safety warning exactly could result in serious injury, death or property damage. Never test for gas leaks with an open flame. use a commerically available soap solution made specifically for the detection of leaks to check all connections. A fire or explosion may result causing property damage, personal injury or loss of life. 6. The furnace and its individual manual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.48kPa). FIGURE 5 - BOTTOM SUPPLY CONNECTION EXTERNAL SHUT-OFF L.P. UNITS, TANKS AND PIPING The furnace must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.48kPa). All gas heat units are shipped from the factory equipped for natural gas use only. The unit may be converted in the field for use with L.P./propane gas with accessory kit model number 1NP0440 or 1NP0485 (2 Stage). 7. A 1/8 inch NPT plugged tap, accessible for test gage connection, must be installed immediately upstream of the gas supply connection to the furnace. All L.P./propane gas equipment must conform to the safety standards of the National Fire Protection Association. For satisfactory operation, adequate L.P./propane gas pressure must be provided at the unit manifold under full load. Maintaining proper gas pressure depends on three main factors: 1. The vaporization rate depends on (a) the temperature of the liquid and (b) the “wetted surface” area of the container or containers. 2. The proper pressure regulation. (Two-stage regulation is recommended from the standpoint of both cost and efficiency.) 3. The pressure drop in the lines between regulators and between the second stage regulator and the appliance. Pipe size required will depend on the length of the pipe run and the total load of all appliances. FIGURE 4 - EXTERNAL SUPPLY CONNECTION EXTERNAL SHUT-OFF 22 Complete information regarding tank sizing for vaporization, recommended regulator settings, and pipe sizing is available from most regulator manufacturers and L.P./propane gas suppliers. Unitary Products Group 170654-YIM-A-1105 L.P./propane gas is an excellent solvent and special pipe compound must be used when assembling piping for this gas as it will quickly dissolve white lead or most standard commercial compounds. Shellac base compounds such as Rectorseal #5 are satisfactory for this type of gas. Check all connections for leaks when piping is completed, using a soap solution. NEVER USE A FLAME. FIRE OR EXPLOSION HAZARD FIGURE 6 - VENT AND COMBUSTION AIR HOOD Failure to follow the safety warning exactly could result in serious injury, death or property damage. Never test for gas leaks with an open flame. use a commercially available soap solution made specifically for the detection of leaks to check all connections. A fire or explosion may result causing property damage, personal injury or loss of life. VENT AND COMBUSTION AIR HOODS The vent hood and combustion air hood (with screens) are shipped attached to the blower housing in the blower compartment. These hoods must be installed to assure proper unit function. All hoods must be fastened to the outside of the gas heat access panel with the screws provided in the bag also attached to the blower housing. The screen for the combustion air intake hood is secured to the inside of the access panel opening with three fasteners and the screws used for mounting the hood to the panel. The top flange of this hood slips in under the top of the access panel opening when installing. Refer to Vent and Combustion Air Hood Figure 6. The vent hood is installed by inserting the top flange of the hood into the slotted opening in the access panel and securing in place. The products of combustion are discharged horizontally through these two screened, hooded vent openings on the upper gas heat access panel. Unitary Products Group An adhesive backed label is provided over the outside of the combustion air inlet opening to prevent moisture from entering the unit, which could cause damage to electrical components. Allow this closure label to remain in place until the combustion air hood is to be installed. ECONOMIZER/MOTORIZED DAMPER AND RAIN HOOD The instruction for the optional economizer/motorized damper and rain hood can be found in form 03507364-000. Use these instructions when field assembling an economizer rain hood onto a unit. The outdoor and return air dampers, the damper actuator, the damper linkage, the outdoor and return air divider baffles, and all the control sensors are factory mounted as part of the “Factory installed” economizer/motorized damper options. POWER EXHAUST/BAROMETRIC RELIEF DAMPER AND RAIN HOOD The instructions for the power exhaust/barometric relief damper and rain hood can be found in form 530.18N1.10V. All of the components, including the dampers, hardware, and mounting instructions are shipped in a single package external from the unit and must be field assembled and installed. 23 170654-YIM-A-1105 Power exhaust is only available as a field installed accessory. ECONOMIZER AND POWER EXHAUST DAMPER SET POINT ADJUSTMENTS AND INFORMATION Remove the economizer access panel from the unit. Loosen but do not remove the two panel latches. Locate the economizer control module, where the following adjustments will be made. Extreme care must be excercised in turning all setpoint, maximium, and minimum damper positioning adjustment screws to prevent twisting them off. Check that the damper blades move smoothly without binding; carefully turn the Minimum Position Adjusting screw (found on the damper control module) fully clockwise and then set the thermostat indoor fan switch to the on position and then off, or energize and deenergize terminals “R” to “G”. MINIMUM POSITION ADJUSTMENT With thermostat set to indoor fan on position, or terminals “R” to “G” energized, turn the Minimum Position Adjusting screw (located on the damper control module) counterclockwise until the desired minimum damper position has been attained. ENTHALPY SET POINT ADJUSTMENT The enthalpy set point may now be set by selecting the desired setpoint shown in the Enthalpy Setpoint Adjustment Figure 7. Adjust as follows: • 24 For a single enthalpy operation carefully turn the set point adjusting screw (found on the damper control module) to the “A”, “B”, “C” or “D” setting corresponding to the lettered curve of the Enthalpy Setpoint Adjustment Figure 7. • For a dual enthalpy operation, carefully turn the set point adjusting screw fully clockwise past the “D” setting. POWER EXHAUST DAMPER SETPOINT (WITH OR WITHOUT POWER EXHAUST) • With no power exhaust option, adjust the Exhaust Air Adjustment Screw fully clockwise. • With power exhaust option, each building pressurization requirement will be different. The point at which the power exhaust comes on is determined by the economizer damper position (Percent Open). The Exhaust Air Adjustment Screw should be set at the Percent Open of the economizer damper at which the power exhaust is needed. It can be set from 0 to 100% damper open. INDOOR AIR QUALITY Indoor Air quality (indoor sensor input): Terminal AQ accepts a +2 to +10 Vdc signal with respect to the (AQ1) terminal. When the signal is below it's setpoint, the actuator is allowed to modulate normally in accordance with the enthalpy and mixed air sensor inputs. When the AQ signal exceeds it's setpoint setting and there is no call for free cooling, the actuator is proportionately modulated from the 2 to 10 Vdc signal, with 2 Vdc corresponding to full closed and 10 Vdc corresponding to full open. When there is no call for free cooling, the damper position is limited by the IAQ Max damper position setting. When the signal exceeds it's setpoint (Demand Control Ventilation Setpoint) setting and there is a call for free cooling, the actuator modulates from the minimum position to the full open position based on the highest call from either the mixed air sensor input or the AQ voltage input. • Optional CO2 Space Sensor Kit Part # 2AQ04700324 • Optional CO2 Unit Sensor Kit Part # 2AQ04700424 Replace the economizer access panel.

Deduct these resistance values from the available external static pressure shown in SUPPLY AIR BLOWER PERFORMANCE Tables. 2. Add these resistance values to the available static resistance values on SUPPLY AIR BLOWER PERFORMANCE Tables. 3. The pressure through the economizer is greater for 100% outdoor air than for 100% return air. If the resistance of the return air duct system is less than 0.25 IWG, the unit will deliver less CFM during full economizer operation. PHASING Check for proper compressor rotation. If the blower or compressors rotate in the wrong direction at start-up, the electrical connection to the unit is misphased. Change the incoming line connection phasing to obtain proper rotation. (Scroll compressors operate in only one direction. If the scroll is drawing low amperage, has similar suction and discharge pressures, or producing a high noise level, the scroll is misphased). Scroll compressors require proper rotation to operate correctly. Do not change the internal wiring to make the blower, condenser fans, or compressor rotate correctly. Change the incoming power to the main terminal block to obtain proper rotation. SUPPLY AIR BLOWERS These blowers have either 3-speed direct drive motors, or single speed motors equipped with a belt drive. Belt drive units have a variable pitch pulley that allows the blower speed to be adjusted. CHECKING SUPPLY AIR CFM The RPM of the supply air blower will depend on the required CFM, the unit accessories or options and the static resistances of both the supply and the return air duct systems. With this information, the motor speed tap (direct drive) or the motor pulley number of turns open (belt drive) can be determined from the Blower Performance Data Tables. 60 FIGURE 16 - BELT ADJUSTMENT Note the following: 1. The supply air CFM must be within the limitations shown in the Unit Application Data Table 1. 2. Pulleys can be adjusted in half turn increments. 3. The tension on the belt should be adjusted as shown in the Belt Adjustment Figure 16. Unitary Products Group 170654-YIM-A-1105 To check the supply air CFM after the initial balancing has been completed: 1. Remove the two 5/16” dot plugs from the blower motor and the filter access panels shown in Figure 15. 2. Insert at least 8" of 1/4 inch tubing into each of these holes for sufficient penetration into the air flow on both sides of the indoor coil. 0.7 072 0.6 PRESSURE DROP (IWG) Start the supply air blower motor. Adjust the resistances in both the supply and the return air duct systems to balance the air distribution throughout the conditioned space.

OPERATION SEQUENCE OF OPERATIONS OVERVIEW 3. Using an inclined manometer, determine the pressure drop across a dry evaporator coil. Since the moisture on an evaporator coil may vary greatly, measuring the pressure drop across a wet coil under field conditions would be inaccurate. To assure a dry coil, the compressors should be deactivated while the test is being run. For these units, the thermostat makes a circuit between “R” and “Y1” for the cooling cycle. 4. Knowing the pressure drop across a dry coil, the actual CFM through the unit can be determined from the curve in Pressure Drop vs. Supply Air CFM (Figure 17). For gas heating, the UCB monitors the “W1” call but does not handle the operation of the gas furnace. An ignition control board controls the gas heater operation. The call is passed to the unit control board (UCB), which then determines whether the requested operation is available and, if so, which components to energize. For electric heat units, the UCB passes the call to the electric heater. Failure to properly adjust the total system air quantity and static pressure can result in extensive system damage. In both cases, when the “W1” call is sensed, the indoor air blower is energized following a specified heating delay. After readings have been obtained, remove the tubes and reinstall the two 5/16” dot plugs that were removed in Step 1. If at any time a call for both heating and cooling are present, the heating operation will be performed. If operating, the cooling system is halted as with a completion of a call for cooling. Heating always takes priority. NOTE: De-energize the compressors before taking any test measurements to assure a dry indoor coil. Unitary Products Group 61 170654-YIM-A-1105 COOLING SEQUENCE OF OPERATION CONTINUOUS BLOWER By setting the room thermostat fan switch to “ON,” the supply air blower will operate continuously. INTERMITTENT BLOWER With the room thermostat fan switch set to “AUTO” and the system switch set to either the “AUTO” or “HEAT” settings, the blower is energized whenever a cooling or heating operation is requested. The blower is energized after any specified delay associated with the operation. When energized, the indoor blower has a minimum run time of 30 seconds. Additionally, the indoor blower has a delay of 10 seconds between operations. NO OUTDOOR AIR OPTIONS When the thermostat calls for cooling, the low-voltage control circuit from “R” to “Y1” and “G” is completed. The compressor and condenser fan motor are energized. After completing the specified fan on delay for cooling, the UCB will energize the blower motor. Once the thermostat has been satisfied, it will de-energize Y1. If the compressor has satisfied its minimum run time, the compressor and condenser fan de-energize. Otherwise, the unit operates the cooling system until the minimum run time for the compressor has been completed. After the compressor de-energizes, the blower is stopped following the elapse of the fan off delay for cooling. To be available, a compressor must not be locked-out due to a high or low-pressure switch or freezestat trip and the anti-short cycle delay (ASCD) must have elapsed. ECONOMIZER WITH SINGLE ENTHALPY SENSOR When the room thermostat calls for cooling, the low voltage control circuit from “R” to “G” and “Y1” is completed. The UCB energizes the blower motor (if the fan switch on the room thermostat is set in the “AUTO” position) and drives the economizer dampers from fully closed to their minimum position. If the enthalpy of the outdoor air is below the setpoint of the enthalpy controller (previously determined), “Y1” energizes the economizer. The dampers will modulate to maintain a 62 constant supply air temperature as monitored by the discharge air sensor. If the outdoor air enthalpy is above the setpoint, “Y1” energizes the compressor and condenser fan motor only. Once the thermostat has been satisfied, it will de-energize “Y1”. If the compressor has satisfied its minimum run time, the compressor and condenser fan are deenergized. Otherwise, the unit operates the cooling system until the minimum run times for the compressor has been completed. After the compressor de-energizes, the blower is stopped following the elapse of the fan off delay for cooling, and the economizer damper goes to the closed position. If the unit is in continues fan operation the economizer damper goes to the min. position. ECONOMIZER WITH DUAL ENTHALPY SENSORS The operation with the dual enthalpy sensors is identical to the single sensor except that a second enthalpy sensor is mounted in the return air. This return air sensor allows the economizer to choose between outdoor air and return air, whichever has the lowest enthalpy value, to provide maximum operating efficiency. ECONOMIZER (SINGLE OR DUAL) WITH POWER EXHAUST This system operates as specified above with one addition. The power exhaust motor is energized 45 seconds after the actuator position exceeds the exhaust fan setpoint on the economizer control. When the power exhaust is operating, the second stage of mechanical cooling will not operate. As always, the “R” to “G” connection provides minimum position but does not provide power exhaust operation. MOTORIZED OUTDOOR AIR DAMPERS This system operation is the same as the units with no outdoor air options with one exception. When the “R” to “G” circuit is complete, the motorized damper drives open to a position set by the thumbnail on the damper motor. When the “R” to “G” circuit is opened, the damper spring returns fully closed. COOLING OPERATION ERRORS Each cooling system is monitored for operation outside of the intended parameters. Errors are handled as described below. All system errors override minimum run times for compressors. Unitary Products Group 170654-YIM-A-1105 HIGH-PRESSURE LIMIT SWITCH During cooling operation, if a high-pressure limit switch opens, the UCB will de-energize the compressor, initiate the ASCD (Anti-short cycle delay), and, stop the condenser fan. If the call for cooling is still present at the conclusion of the ASCD, the UCB will re-energize the compressor. Should a high-pressure switch open three times within two hours of operation, the UCB will lock-out the compressor and flash a code (see Table 53). LOW-PRESSURE LIMIT SWITCH The low-pressure limit switch is not monitored during the initial 30 seconds of a cooling system's operation. For the following 30 seconds, the UCB will monitor the low-pressure switch to ensure it closes. If the low-pressure switch fails to close after the 30-second monitoring phase, the UCB will de-energize the compressor, initiate the ASCD, and stop the condenser fan. ature-activated switch set at 45ºF. When the low ambient switch is closed and the thermostat is calling for cooling, the UCB will operate in the low ambient mode. Low ambient mode operates the compressors in this manner: 10 minutes on, 5 minutes off. The indoor blower is operated throughout the cycle. The 5-minute off period is necessary to defrost the indoor coil. Low ambient mode always begins with compressor operation. Compressor minimum run time may extend the minutes of compressor operation. The defrost cycle will begin immediately following the elapse of the minimum run time. When operating in low ambient mode, the UCB will not lockout the compressor due to a freezestat trip. However, a freezestat trip will de-energize the compressor. If the call for cooling is still present at the end of the ASCD and the freezestat has closed, the unit will resume operation. SAFETY CONTROLS Once the low-pressure switch has been proven (closed during the 30-second monitor period described above), the UCB will monitor the low-pressure limit switch for any openings. If the low-pressure switch opens for greater than 5 seconds, the UCB will de-energize the compressor, initiate the ASCD, and stop the condenser fan. If the call for cooling is still present at the conclusion of the ASCD, the UCB will re-energize the compressor. Should a low-pressure switch open three times within one hour of operation, the UCB will lock-out the compressor and flash a code (Table 53). FREEZESTAT During cooling operation, if a freezestat opens, the UCB will de-energize the compressor, initiate the ASCD, and stop the condenser fan. If the call for cooling is still present at the conclusion of the ASCD, the UCB will re-energize the compressor. The unit control board monitors the following inputs for the cooling system: 1. A suction line freezestat to protect against low evaporator temperatures due to a low airflow or a low return air temperature, (opens at 26 ± 5 °F and resets at 38 ± 5°F). 2. A high-pressure switch to protect against excessive discharge pressures due to a blocked condenser coil or a condenser motor failure, (opens at 380 ± 10 psig and resets at 300 ± 10 psig). 3. A low-pressure switch to protect against loss of refrigerant charge, (opens at 7 ± 3 psig and resets at 22 ± 5 psig). The above pressure switches are hard-soldered to the unit. The refrigeration system is monitored and controlled. On any fault, the system will be affected by any safety/preventive action. Should a freezestat open three times within two hours of operation, the UCB will lock-out the compressor and flash a code (Table 53). The unit control board monitors the temperature limit switch of electric heat units and the temperature limit switch and the gas valve of gas furnace units. LOW AMBIENT COOLING COMPRESSOR PROTECTION To determine when to operate in low ambient mode, the UCB has a pair of terminals connected to a temper- The compressor also has inherent (internal) protection. If there is an abnormal temperature rise in a compres- Unitary Products Group 63 170654-YIM-A-1105 sor, the protector will open to shut down the compressor. The UCB incorporates features to minimize compressor wear and damage. An anti-short cycle delay (ASCD) is utilized to prevent operation of a compressor too soon after its previous run. Additionally, a minimum run time is imposed any time a compressor is energized. The ASCD is initiated on unit start-up and on any compressor reset or lock-out. FLASH CODES The UCB will initiate a flash code associated with errors within the system. Refer to UNIT CONTROL BOARD FLASH CODES Table 53. RESET Remove the call for cooling, by raising thermostat setting higher than the conditioned space temperature. This resets any pressure or freezestat flash codes. ELECTRIC HEATING SEQUENCE OF OPERATIONS After completing the specified fan on delay for heating, the UCB will energize the blower motor. b. The thermostat will cycle the electric heat to satisfy the heating requirements of the conditioned space. SAFETY CONTROLS The control circuit includes the following safety controls: 1. Temperature Limit Switch (TLS) - This control is located inside the heater compartment and is set to open at the temperature indicated in the Electric Heat Limit Control Setting Table 47. It resets automatically. The limit switch operates when a high temperature condition, caused by inadequate supply air flow occurs, thus shutting down the heater and energizing the blower. TABLE 47: ELECTRIC HEAT LIMIT CONTROL SETTING VOLTAGE The following sequence describes the operation of the electric heat section. 230-1-60 Single-stage heating (applies only to 5, 7 & 10 kW 230V heaters and to 7, 10, & 15 kW 460V and 575V heaters. All other heaters MUST use a two-stage thermostat): a. Upon a call for heat by the thermostat, the heater sequencer (1S) will be energized. After completing the specified fan on delay for heating, the UCB will energize the blower motor. kW 5 1 140 7 1,3 140 10 1,2,3 140 2,4,6 140 1,2,3,4,5 140 15 20 230-3-60 6 150 30 1,2,3,4,5,6 150 5 1,2,3 140 7 1,2,3 140 10 1,2,3 150 15 2,4,6 140 20 1,2,3,4,5,6 150 30 b.

Two-stage heating (applies only to 15, 20 and 30 kW 230V heaters and 20 and 30 kW heater 460V and 575V heaters.): a. Upon a call for first-stage heat by the thermostat, the heater sequencer (1S) (15, 20, 30 kW 230 volt) and contactor (2M) (20, 30 kW 460 and 575 volt) will be energized. After completing the specified fan on delay for heating, the UCB will energize the blower motor. 460-3-60 575-3-60 º TEMPERATURE LIMIT SWITCH Open Temp F 1,3,5 160 2,4,6 150 7 2,4,6 140 10 2,4,6 140 15 2,4,6 140 20 3 160 30 3 150 10 2,4,6 140 15 2,4,6 140 20 5 160 30 5 150 If the second stage of heat is required, heater sequencer (2S) (12, 20, 30 kW 230 volt) or contactor (3M) (20, 30 kW 460 and 575 volt) will be energized. 64 Unitary Products Group 170654-YIM-A-1105 shaft, closes to power the ignition module (IC), through the “RW1-1” contacts. RESET Remove the call for heating by lowering the thermostat setting lower than the conditioned space temperature. This resets any flash codes. HEAT ANTICIPATOR SETPOINTS It is important that the anticipator setpoint be correct. Too high of a setting will result in longer heat cycles and a greater temperature swing in the conditioned space. Reducing the value below the correct setpoint will give shorter “ON” cycles and may result in the lowering of the temperature within the conditioned space. Refer to Table 48 for the required heat anticipator setting.

The heat relay “RW1” is energized. The “RW1-2” contacts close energizing the draft motor control (DMC). The draft motor control contacts close and start the draft motor. As the speed of the draft motor reaches approximately 2500 RPM, the centrifugal switch contact, located on the end of the draft motor Unitary Products Group Ignition module “IC” will immediately start the igniter sparking and will open the redundant valve located inside the main gas valve “GV” to allow a flow of gas to the carryover tube. Only after the pilot flame has been ignited and the presence of pilot flame detected at the “IC” by a signal sent back through the flame sensor is sparking terminated and the main gas valve opened. Gas flows into each of the main burners and is ignited from the carryover tube flame. After completing the specified fan on delay for heating, the UCB will energize the blower motor. If “IC” fails to detect a pilot flame, it will continue to try for a maximum of 85 seconds to ignite the pilot tube. If the pilot flame is not detected, then “IC” will lock out furnace operation for five minutes or until 24V power is removed from the module either at the unit or by resetting the room thermostat. When the thermostat satisfies de-energizing the “RW1”, thus opening the gas valve. The blower motor will continue to run after the furnace is shut down until the specified fan off delay for heating has been satisfied. The UCB will de-energize the blower motor. REDUNDANT VALVE MAIN VALVE GAS MAIN GAS VALVE TO PILOT BURNER TO MAIN BURNER FIGURE 18 - GAS VALVE PIPING When the thermostat calls for the first stage of heating, the low-voltage control circuit from “R” to “W1” is completed. A call for heat passes through the UCB to the ignition control board (ICB). The UCB monitors the “W1” call and acts upon any call for heat. Once voltage has been sensed at “W1”, the UCB will initiate the fan on delay for heating, energizing the indoor blower after the specified delay has elapsed. When the thermostat has been satisfied, heating calls are ceased. The GV is immediately de-energized. The 65 170654-YIM-A-1105 blower is de-energized after the fan off delay for heating has elapsed. The draft motor performs a 25-second post purge. GAS HEATING SEQUENCE OF OPERATION (2 STAGE) When there is a W1 call for heat, the heat relay is energized by the unit control board. The heat relay contacts immediately close energizing the ignition control board. The ignition control board checks the state of the limits and the centrifugal switch. If they are in the expected state, then the draft motor contact on the ignition control board closes energizing the draft motor. As the speed of the draft motor reaches approximately 2500 rpm, the centrifugal switch located on the end of the draft motor shaft closes and the ignition control board starts a 15 second pre-purge period. After the prepurge period the ignition control board will simultaneously start the igniter sparking and open the pilot gas valve to allow flow of gas to the pilot burner. After the pilot flame is sensed by the flame sensor the igniter sparking ceases. After the pilot flame stability is proven the ignition control board applies power to the main gas valve for full fire operation. Gas flows into each of the main burners and is ignited from the pilot burner flame. After completing the specified fan on delay for heating, the unit control board will energize the blower motor. One minute after main burner ignition the ignition control board will reduce the manifold pressure and draft motor speed for low fire operation. When there is a W2 call for heat, the sequence above is the same except for the reduction to low fire operation after one minute. If a W2 call for heat comes after a W1 ignition sequence is started, then the ignition control either finishes the ignition sequence and continues in the full fire operation or immediately calls for full fire operation. An automatic 2 stage operation feature is available for use with a single stage thermostat. To activate the automatic 2 stage feature install a jumper between R and W2 on the terminal strip of the unit control board. The ignition control board interprets the continuous 24V power on W2 terminal as automatic 2 stage operation. Therefore, when it receives a call for heat from a single stage thermostat it will start the automatic 2 stage operation. Upon receiving a call for heat signal the ignition control board will sequence the same as a W1 only call for heat above for 10 minutes. After 10 minutes, the ignition control board will move to full firing rate until the call for heat is satisfied. Each time a call 66 for heat is received the ignition control board will go through this same sequence. When the call for heat is satisfied, the unit control board de-energizes heat relay which signals the ignition control board to close both the main and pilot valves. The unit control board will de-energize the blower motor after the selected time and the ignition control board will de-energize the draft motor after a specific time. GAS HEATING OPERATION ERRORS TEMPERATURE LIMIT If the UCB senses zero volts from the high temperature limit, the indoor blower motor is immediately energized. When the UCB again senses 24 volts from the temperature limit, the draft motor will perform a 25-second post-purge and the indoor blower will be de-energized following the elapse of the fan off delay for heating. The temperature limit is monitored at all times. If the temperature limit opens three times within one hour, it will lock-on the indoor blower motor and a flash code is initiated (See Table 53). GAS VALVE The UCB continuously monitors the GV. Any time the UCB senses voltage at the GV without a call for heat for a continuous five-minute period, the UCB will lockon the indoor blower and a flash code is initiated (Table 53). When voltage is no longer sensed at the GV, the UCB will de-energize the indoor blower following the elapse of the fan off delay for heating. If voltage has been sensed at the GV for at least 15 seconds during the fan on delay for heating and GV voltage or “W1” is lost, the indoor blower is forced on for the length of the fan off delay for heating. SAFETY CONTROLS The unit control board monitors the temperature limit switch and the gas valve of gas furnace units. The control circuit includes the following safety controls: 1. Limit Control (LS) - This control is located inside the heat exchanger compartment and is set to open at the temperature indicated in the Gas Heat Unitary Products Group 170654-YIM-A-1105 Limit Control Setting Table 49. It resets automatically. The limit switch operates when a high temperature condition, caused by inadequate supply air flow occurs, thus shutting down the ignition control and closing the main gas valve and energizing the blower. TABLE 49: SINGLE STAGE GAS HEAT LIMIT CONTROL SETTING 2. Centrifugal Switch (CS) - If the draft motor should fail, the centrifugal switch attached to the shaft of the motor prevents the ignition control and gas valve from being energized. 3. Redundant Gas Valve - This valve is an integral part of the main gas valve and is located up stream of the main gas valve. Should the main gas valve fail in the open position, the redundant valve serves as a back-up and shuts off the flow of gas. 4. Flame Sensor Rod / 100% Ignition Control LockOut - The flame rods and controls are located per Proper Flame Adjustment Figure 21. If an ignition control fails to detect a signal from the flame sensor indicating the pilot flame is properly ignited, then the main gas valve will not open. It will continue to try and ignite the pilot for a maximum of 85 seconds, then if the pilot flame is not detected, the ignition control will lock out furnace operation until 24V power is removed from the module either at the unit or by resetting the room thermostat. 5. Rollout Switch (RS) - This switch is located in the burner vestibule. In the event of a sustained main burner flame rollout, it shuts off the ignition control and closes the main gas valve.

If AUX trips, then the primary limit has not functioned correctly. Replace the primary limit. Unitary Products Group The UCB will initiate a flash code associated with errors within the system. Refer to UNIT CONTROL BOARD FLASH CODES Table 53. 67 170654-YIM-A-1105 RESETS OPERATING INSTRUCTIONS Remove the call for heating by lowering the thermostat setting lower than the conditioned space temperature. This resets any flash codes. 1. Turn unit electrical power on. 2. Set the room thermostat setting to lower than the room temperature. HEAT ANTICIPATOR SETPOINTS It is important that the anticipator setpoint be correct. Too high of a setting will result in longer heat cycles and a greater temperature swing in the conditioned space. Reducing the value below the correct setpoint will give shorter “ON” cycles and may result in the lowering of the temperature within the conditioned space. 3. First stage compressors will energize after the built-in time delay (five minutes). 4. The second stage of the thermostat will energize second stage compressor if needed. POST START CHECK LIST 1.

PRESTART CHECK LIST SHUT DOWN After installation has been completed: 1. Set the thermostat to highest temperature setting. 1. Check the electrical supply voltage being supplied. Be sure that it is the same as listed on the unit nameplate. 2. Set the room thermostat to the off position. 3. Turn unit electrical power on. 4. Set the room thermostat fan switch to on. 5. Check indoor blower rotation. • If blower rotation is in the wrong direction. Refer to Phasing Section in general information section. • Check blower drive belt tension. 2. Turn off the electrical power to the unit. START-UP (GAS HEAT) PRE-START CHECK LIST Complete the following checks before starting the unit. 1. Check the type of gas being supplied. Be sure that it is the same as listed on the unit nameplate. 2. Make sure that the vent and combustion air hoods have been properly installed. OPERATING INSTRUCTIONS 6. Check the unit supply air (CFM). See “CHECKING SUPPLY AIR CFM” on page 60. 7. Measure evaporator fan motor's amp draw. 8. Set the room thermostat fan switch to off. This furnace is equipped with an intermittent pilot and automatic re-ignition system. DO NOT attempt to manually light the pilot. 9. Turn unit electrical power off. 68 Unitary Products Group 170654-YIM-A-1105 TO LIGHT PILOT AND MAIN BURNERS: 1. Turn “off” electric power to unit. 2. Turn room thermostat to lowest setting. 3. Turn gas valve knob or switch to “on” position. pressure should be checked with all gas appliances in the building at full fire. At no time should the standby gas line pressure exceed 13", nor the operating pressure drop below 5.0" for natural gas units. If gas pressure is outside these limits, contact the local gas utility for corrective action. 4. Turn “on” electric power to unit. 5. Set room thermostat to desired temperature. (If thermostat “set” temperature is above room temperature, pilot burner ignition will occur and, after an interval to prove pilot flame, main burners will ignite). TO SHUT DOWN: 1. Turn “off” electric power to unit. 2. Depress knob of gas valve while turning to “off” position or position the switch to the “off” position.

BURNER INSTRUCTIONS To check or change burners, pilot or orifices, CLOSE MAIN MANUAL SHUT-OFF VALVE AND SHUT OFF ALL ELECTRIC POWER TO THE UNIT. 70 CHECKING GAS INPUT NATURAL GAS 1. Turn off all other gas appliances connected to the gas meter. 2. With the furnace turned on, measure the time needed for one revolution of the hand on the smallest dial on the meter. A typical gas meter usually has a 1/2 or a 1 cubic foot test dial. 3. Using the number of seconds for each revolution and the size of the test dial increment, find the cubic feet of gas consumed per hour from the Gas Rate - Cubic Feet Per Hour (Table 52). If the actual input is not within 5% of the furnace rating (with allowance being made for the permissible range Unitary Products Group 170654-YIM-A-1105 of the regulator setting), replace the orifice spuds with spuds of the proper size. NOTE: To find the Btu input, multiply the number of cubic feet of gas consumed per hour by the Btu content of the gas in your particular locality (contact your gas company for this information - it varies widely from city to city.) ADJUSTMENT OF TEMPERATURE RISE The temperature rise (or temperature difference between the return air and the heated air from the furnace) must lie within the range shown on the rating plate and the data in the Gas Heat Application Table 4.

Btuh Input x 0.8 108 . x oF Temp. Rise After the temperature rise has been determined, the cfm can be calculated as follows: After about 20 minutes of operation, determine the furnace temperature rise. Take readings of both the return air and the heated air in the ducts (about six feet from the furnace) where they will not be affected by radiant heat. Increase the blower cfm to decrease the temperature rise; decrease the blower cfm to increase the rise. Refer to the Blower Motor and Drive Data Table 45. TROUBLESHOOTING COOLING TROUBLESHOOTING GUIDE Troubleshooting of components may require opening the electrical control box with the power connected to the unit. Use extreme care when working with live circuits! Check the unit nameplate for the correct line voltage and set the voltmeter to the correct range before making any connections with line terminals. Shut off all electric power to the unit prior to any of the following maintenance procedures to prevent personal injury. By actual measurement, it takes 38 seconds for the hand on the 1-cubic foot dial to make a revolution with a 100,000 Btuh furnace running. Using this information, located 38 seconds in the first column in the table above. Read across to the column headed “1 Cubic Foot”, where you will see that 95 cubic feet of gas per hour are consumed by the furnace at that rate. Multiply 95 X 1050 (the Btu rating of the gas obtained from the local gas company). The result is 99,750 Btuh, which is close to the 100,000 Btuh rating of the furnace. Unitary Products Group 71 170654-YIM-A-1105 volts are not present from the room thermostat, check for the following: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation, which could cause injury to person and/or damage unit components. Verify proper operation after servicing. On calls for cooling, if the compressors are operating but the supply air blower motor does not energize after a short delay (the room thermostat fan switch is in the “AUTO” position). 1. Turn the thermostat fan switch to the ON position. If the supply air blower motor does not energize, go to Step 3. 2. If the blower motor runs with the fan switch in the ON position but will not run after the compressor has energized when the fan switch is in the AUTO position, check the room thermostat for contact between R and G in the AUTO position during calls for cooling. 3. If the supply air blower motor does not energize when the fan switch is set to ON, check that line voltage is being supplied to the contacts of the M2, contactor, and that the contactor is pulled in. Check for loose wiring between the contactor and the supply air blower motor. 4. If M2 is pulled in and voltage is supplied to M2, lightly touch the supply air blower motor housing. If it is hot, the motor may be off on internal protection. Cancel any thermostat calls and set the fan switch to AUTO. Wait for the internal overload to reset. Test again when cool. 5. If M2 is not pulled in, check for 24 volts at the M2 coil. If 24 volts are present at M2 but M2 is not pulled in, replace the contactor. a. Proper operation of the room thermostat (contact between R and G with the fan switch in the ON position and in the AUTO position during operation calls). b. Proper wiring between the room thermostat and the UCB. c. Loose wiring from the room thermostat to the UCB. 9. If 24 volts is present at the room thermostat but not at the UCB, check for proper wiring between the thermostat and the UCB, i.e. that the thermostat G terminal is connected to the G terminal of the UCB, and for loose wiring. 10. If the thermostat and UCB are properly wired, replace the UCB. On a call for cooling, the supply air blower motor is operating but the compressor is not (the room thermostat fan switch is in the “AUTO” position). 1. If installed, check the position of the economizer blades. If the blades are open, the economizer is providing free cooling and the compressors will not immediately operate. If both stages of cooling are requested simultaneously and the economizer provides free cooling, following a short delay the compressor will be energized unless it is locked out, unless this option has been disabled through computer communications. 2. If no economizer is installed or the economizer is not opening to provide free cooling and the compressor does not energize on a call for cooling, check for line voltage at the compressor contactor, M1, and that the contactor is pulled in. Check for loose wiring between the contactor and the compressor. 6. Failing the above, if there is line voltage supplied at M2, M2 is pulled in, and the supply air blower motor still does not operate, replace the motor. 3. If M1 is pulled in and voltage is supplied at M1, lightly touch the compressor housing. If it is hot, the compressor may be off on inherent protection. Cancel any calls for cooling and wait for the internal overload to reset. Test again when cool. 7. If 24 volts is not present at M2, check that 24 volts is present at the UCB supply air blower motor terminal, “FAN”. If 24 volts is present at the FAN, check for loose wiring between the UCB and M2. 4. If M1 is not pulled in, check for 24 volts at the M1 coil. If 24 volts are present and M1 is not pulled in, replace the contactor. 8. If 24 volts is not present at the “FAN” terminal, check for 24 volts from the room thermostat. If 24 72 Unitary Products Group 170654-YIM-A-1105 5. Failing the above, if voltage is supplied at M1, M1 is pulled in, and the compressor still does not operate, replace the compressor. 6. If 24 volts is not present at M1, check for 24 volts at the UCB terminal, C1. If 24 volts is present, check for loose wiring between C1 and the compressor contactor. 7. If 24 volts is not present at the C1 terminal, check for 24 volts from the room thermostat at the UCB Y1 terminal. If 24 volts is not present from the room thermostat, check for the following: a. 24 volts at the thermostat Y1 terminal b. Proper wiring between the room thermostat and the UCB, i.e. Y1 to Y1, Y2 to Y2 c. Loose wiring from the room thermostat to the UCB. 8. If 24 volts is present at the UCB Y1 terminal, the compressor may be out due to an open high-pressure switch, low-pressure switch, or freezestat. Check for 24 volts at the HPS1, LPS1, and FS1 terminals of the UCB. If a switch has opened, there should be a voltage potential between the UCB terminals, e.g. if LPS1 has opened, there will be a 24volt potential between the LPS1 terminals. 9. If 24 volts is present at the UCB Y1 terminal and none of the protection switches have opened, the UCB may have locked out the compressor for repeat trips. The UCB should be flashing an alarm code. If not, press and release the ALARMS button on the UCB. The UCB will flash the last five alarms on the LED. If the compressor is locked out, cancel any call for cooling. This will reset any compressor lock outs. NOTE: While the above step will reset any lockouts, the compressor may be held off for the ASCD. See the next step. 10. If 24 volts is present at the UCB Y1 terminal and none of the switches are open and the compressor is not locked out, the UCB may have the compressor in an ASCD. Check the LED for an indication of an ASCD cycle. The ASCD should time out within 5 minutes. Press and release the TEST button to reset all ASCDs. Unitary Products Group 11. If 24 volts is present at the UCB Y1 terminal and the compressor is not out due to a protective switch trip, repeat trip lock out, or ASCD, the economizer terminals of the UCB may be improperly wired. Check for 24 volts at the Y1 “OUT” terminal of the UCB. If 24 volts is present, trace the wiring from Y1 “OUT” for incorrect wiring. If 24 volts is not present at the Y1 “OUT” terminal, the UCB must be replaced. 12. For units without economizers: If 24 volts is present at the Y1 OUT terminal, check for 24 volts at the Y1 “ECON” terminal. If 24 volts is not present, check for loose wiring from the Y1 “OUT” terminal to the Mate-N-Lock plug, the jumper in the Mate-N-Lock plug, and in the wiring from the MateN-Lock plug to the Y1 “ECON” terminal. 13. For units with economizers: If 24 volts is present at the Y1 “OUT” terminal, check for 24 volts at the Y1 “ECON” terminal. If 24 volts is not present, check for loose wiring from the Y1 “OUT” terminal to the Mate-N-Lock plug, a poor connection between the UCB and economizer Mate-N-Lock plugs, loose wiring from the Mate-N-Lock plug to the economizer, back to the Mate-N-Lock plug, and from the Mate-N-Lock plug to the Y1 “ECON” terminal. If nothing is found, the economizer actuator may have faulted and is failing to return the 24-volt “call” to the Y1 “ECON” terminal even though the economizer is not providing free cooling. To test, disconnect the Mate-N-Locks and jumper between the WHITE and YELLOW wires of the UCB’s Mate-NLock plug. If the compressor energizes, there is a fault in the economizer wiring or actuator. 14. The UCB can be programmed to lock out compressor operation during free cooling and in low ambient conditions. These options are not enabled by default. Local distributors can test the UCB for this programming. 15. If none of the above correct the error, replace the UCB. 73 170654-YIM-A-1105 GAS HEAT TROUBLESHOOTING GUIDE energize after a short delay (the room thermostat fan switch is in “AUTO” position). 1. Place the thermostat fan switch in the “ON” position. If the supply air blower motor energizes, go to Step 10. Troubleshooting of components may require opening the electrical control box with the power connected to the unit. Use extreme care when working with live circuits! Check the unit nameplate for the correct line voltage and set the voltmeter to the correct range before making any connections with line terminals. When not necessary, shut off all electric power to the unit prior to any of the following maintenance procedures so as to prevent personal injury. 2. If the supply air blower motor does not energize when the fan switch is set to “ON,” check that line voltage is being supplied to the contacts of the M2 contactor, and that the contactor is pulled in. Check for loose wiring between the contactor and the supply air blower motor. 3. If M2 is pulled in and voltage is supplied at M2, lightly touch the supply air blower motor housing. If it is hot, the motor may be off on inherent protection. Cancel any thermostat calls and set the fan switch to “AUTO”, wait for the internal overload to reset. Test again when cool. 4. If M2 is not pulled in, check for 24 volts at the M2 coil. If 24 volts is present at M2 but M2 is not pulled in, replace the contactor. Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation, which could cause injury to person and/or damage unit components. Verify proper operation after servicing. NOTE: To find the Btu input, multiply the number of cubic feet of gas consumed per hour by the Btu content of the gas in your particular locality (contact your gas company for this information - it varies widely from city to city.). The furnace may shut down on a high temperature condition during the procedure. If this occurs, the UCB energize the supply air blower motor until the high temperature limit has reset. Caution should be used at all times as the supply air blower may energize regardless of the room thermostat fan switch position. On calls for heating, the draft motor operates and the furnace lights but the supply air blower motor does not 74 5. Failing the above, if there is line voltage supplied at M2, M2 is pulled in, and the supply air blower motor still does not operate, replace the motor. 6. If 24 volts is not present at M2, check that 24 volts is present at the supply air blower motor terminal on the UCB. If 24 volts is present at the UCB terminal, check for loose wiring between the UCB and M2. 7. If 24 volts is not present at the UCB supply air blower motor terminal, check for 24 volts from the room thermostat. If 24 volts is not present from the room thermostat, check for the following: a. Proper operation of the room thermostat (contact between R and G with the fan switch in the “ON” position and in the “AUTO” position during operation calls). b. Proper wiring between the room thermostat and the UCB. c. Loose wiring from the room thermostat to the UCB. 8. If 24 volts is present at the room thermostat but not at the UCB, check for proper wiring between the thermostat and the UCB, i.e. that the thermostat G terminal is connected to the G terminal of the UCB, and for loose wiring. Unitary Products Group 170654-YIM-A-1105 9. If the thermostat and UCB are properly wired, replace the UCB. 10. If the blower motor runs with the fan switch in the “ON” position but does not run shortly after the furnace has ignited when the fan switch is in the “AUTO” position, check the room thermostat for contact between R and G during “W1” calls. On calls for heating, the supply air blower operates but the draft motor does not (the room thermostat fan switch is in the “AUTO” position). 1. The draft motor has inherent protection. If the motor shell is hot to the touch, wait for the internal overload to reset. 2. If the motor shell is cold with the room thermostat calling for heat, check if 24 volts is present at the room thermostat but not at the UCB, check for proper wiring between the thermostat and the UCB, i.e. that the thermostat “W1” terminal is connected to the “W1” terminal of the UCB, and for loose wiring. 3. Check if the Draft Motor Control (DMC) is not pulled in, check for 24 volts at the DMC terminals “G” and “C”. If 24 volts is present, replace the DMC. If 24 volts is not present, check for a loose 24 volt connection back to terminal “H1” on the UCB. On a 2 stage model, the draft motor is a 230 volt motor on all models regardless of unit supply voltage. Verify that terminal "L1" on the ignition control board has a minimum of 187 volts present. If terminal "L1" does not have the minimum voltage present, then check the wiring to the ignition control board on all models and on 460V and 575V models check the transformers ahead of the ignition board. If "L1" does have the minimum voltage present, then verify minimum voltage is present at terminal "IND HIGH" on the ignition control board. If minimum voltage is present at "IND HIGH", then draft motor or its run capacitor is at fault and will require replacement. 4. Check if line voltage is present at the DMC terminals “COM” to “NO”. If the line voltage is present replace the DMC. If line voltage is not present check voltage from terminal “L3” of M1 contactor to terminal “NO” on the DMC, if line voltage is present replace the draft motor. On a 2 stage models, if the minimum voltage is present at terminal "L1" and not present at terminal "IND HIGH", then verify that the LED on the ignition control board indicates a heartbeat defined as a Unitary Products Group constant flashing of the LED. If the led does not flash, then check the 24V continuous power circuit to the ignition control board as well as the common circuit wiring. If a pause is present between any number of flashes then a fault code has been set. At this point, 3 flashes followed by a pause repeated over and over is an indication that the centrifugal switch is stuck in the closed position which can be verified by the presence of 24V between terminals P2-1 and P1-8. In this case the ignition control board will not energize the draft motor for safety reasons. Replace the draft motor or repair the centrifugal switch in the bottom of the draft motor. If all tests are as expected and the board has constant flashing of the LED, then replace the ignition control board. The draft motor runs but the furnace does not light and the sparker does not spark. 1. The ignition control (IC) may be locked out due to either a flame roll out or 100% shut off. These safety features are described above. If lock-out has occurred, 24V must be removed from the ignition controls. This is done at the unit or by resetting the room thermostat. After resetting 24V, check for proper furnace operation. If lock-out continues to occur, locate the source of the problem and correct. 2. Check all 24 volt connections from the UCB to and in the gas heat section. Check low voltage connections to the relay (RW1) located in the control box. 3. If the furnace is hot, it may be out on an over-temperature condition, wait for limit reset. 4. If the furnace is cold, check for 24 volts at terminal “5” and “7” of RW1. If 24 volts is present, check the RW1 relay coil terminals “A” and “B”. If 24 volts is found at the coil replace the RW1 relay. 5. If 24 volts is not present at terminals “5” and “7” and the RW1 relay coil is pulled in. Check for 24 volts from terminal “5” to “Ground” on the RW1 relay. 24 volts here indicates that the problem is in the (RS) Roll Out Switch, or the (CS) Centrifugal Switch. On two stage models, if 24V is present at terminals "5" and "7" and the RW1 coil is pulled in then check verify that the LED on the ignition control board is constantly flashing. If so, then check wiring between ignition control board and gas valve. If the flashing is broken by a pause, then count the 75 170654-YIM-A-1105 flashes between the pauses to determine the reason for the lockout. 6. With the draft motor running, check for 24 volts at terminal “TH” to “Ground” on the ignition control (IC) where the red lead from the draft motor attaches. If 24 volts is not present, the centrifugal switch (CS) has not closed or has gone bad. Check the line voltage to the unit, if it is correct replace the draft motor. If line voltage is low call the power company. On two stage models, if flash code is a 2 then verify that 24V is not present between P2-1 and P1-8. If 24V is not present, then the centrifugal switch has not closed. This could be due to low voltage to the draft motor. Verify that the voltage at terminal "IND HIGH" is a minimum of 187 volts. If it is at least 187 volts, then replace the draft motor or repair the centrifugal switch in the bottom of the draft motor. If the voltage is less than 187 volts, then call the power company. 7. If 24 volts is present at the ignition control, check all control wiring at the ignition control and the wire to the ignitor. Check that the ground wires from the ignition control, the gas valves and pilot burners are all intact and making good electrical connection. Check to make sure that the ceramic insulator on the pilot ignitor or sensors is not broken or cracked, if all are intact, replace the ignition control IC. The draft motor runs and the ignitor sparks at the pilot burner but the pilot does not ignite and a gas odor is not detected at the draft motor outlet. 1. Check to make sure gas is being supplied to the unit. Make sure that the gas pressure to the unit is within the proper limits as described in the “POST START CHECK LIST” on page 69 and that the pilot adjust screw is allowing some flow of gas as described in “PILOT CHECKOUT” on page 70. 2. Check all wiring between the ignition control and the gas valve. Check to make sure the ground connections are intact. 4. If 24 volts is present, remove the pilot burner and remove the pilot orifice from the pilot burner. The orifice is removed in the direction opposite the flow of gas. Inspect the orifice for obstruction. If it is clear, replace the main gas valve. The ignitor sparks at the pilot burner but the pilot does not ignite and a gas odor is detected at the draft motor outlet. 1. Adjust the pilot adjust screw on the gas valve as described in “PILOT CHECKOUT” on page 70. 2. Check the supply pressure as described in “POST START CHECK LIST” on page 69. Make adjustments as necessary. 3. Check the pilot orifice and pilot burner for obstruction as described in paragraph above. Clean as needed but the problem should not be the gas valve. The pilot burner ignites but the ignitor continues to spark and the main burners do not ignite. 1. Make the same checks and adjustment as described in “PILOT CHECKOUT” on page 70. 2. Check the supply pressure as described in “POST START CHECK LIST” on page 69. Make adjustments as necessary. 3. Make sure that the pilot burner is not bent or damaged. 4. Make sure that the ground connections at the pilot burner, gas valve and ignition control are intact. Check the ignitor wire for good electrical connection. If all are intact, replace the ignition module. The pilot burner lights and the spark stops but the main burners do not light. 1. Check electrical connections between the ignitor control and the gas valve. If intact, check for 24 volts across terminals “MV” and “GROUND” terminals. If no voltage detected, replace ignition control. If voltage is present, replace gas valve. 3. If the wiring is intact, check for 24 volts across terminals “PV” and “GROUND” on the ignition control. If 24 volts is not present, replace the ignition control. 76 Unitary Products Group 170654-YIM-A-1105 Furnace lights with roll-out or one burner has delayed ignition. 1. Make sure that the pilot burner is aligned properly with the flame sensor as described in “PILOT CHECKOUT” on page 70. Main burners light but exhibit erratic flame characteristics. 1. Adjust air shutters as described in “BURNER AIR SHUTTER ADJUSTMENT” on page 70. 2. Check the main burner orifices for obstruction and alignment. Removal procedure is described in BURNER INSTRUCTIONS on page 70. Clean or replace burner orifices and burners as needed. TABLE 53: UNIT CONTROL BOARD FLASH CODES Flash Code On Steady Control Failure - Replace Control Heart Beat Normal Operation 1 Flash Current alarms or active restrictions are flashed on the UCB LED. Pressing and releasing the ALARMS button on the UCB can check the alarm history. The UCB will cycle through the last five (5) alarms, most recent to oldest, separating each alarm flash code by approximately 2 seconds. In some cases, it may be necessary to “zero” the ASCD for the compressors in order to perform troubleshooting. To reset all ASCDs for one cycle, press and release the UCB TEST button once.

Flash codes are distinguished by the short on and off cycle used (approximately 200ms on and 200ms off). To show normal operation, the control board flashes a 1 second on, 1 second off “heartbeat” during normal operation. This is to verify that the UCB is functioning correctly. Do not confuse this with an error flash code. To prevent confusion, a 1-flash, flash code is not used.
