• The thermostat should be mounted about 5 feet above the ﬂ oor on an inside wall. DO NOT install the thermostat on an outside wall or any other location where its operation may be adversely affected by radiant heat from ﬁ replaces, sunlight, or lighting ﬁ xtures, and convective heat from warm air registers or electrical appliances. Ref er to the thermostat manufacturer’s instruction sheet f or detailed mounting information.

Checking Heat Anticipator Settings

• Add the current draw of the system components.

• Measure the current ﬂ ow on the thermostat R-W circuit after the circulating blower motor has started. Set the heat anticipator according to the thermostat manufacturer’s instructions for heat anticipator settings.

Optional Outdoor Thermostat If two stage heating is desired, an outdoor thermostat can be installed in the ﬁ eld with 2-stage electric heat. To install the outdoor thermostat, remove the orange wire from the E terminal on the terminal block, and connect to the outdoor thermostat. Connect the other side of the outdoor thermostat to W2 from the thermostat.

Blower Speed

The blower speed is preset at the f actory for operation at the same speed for heating and cooling. These factory settings are listed in Table 10 (page 25). For optimum system performance and comfort, it may be necessary to change the factory set speed.

Unbalanced 3-Phase Supply Voltage

V oltage unbalance occurs when the voltages of all phases of a 3-phase power supply are no longer equal. This unbalance reduces motor efﬁ ciency and performance. Some underlying causes of voltage unbalance may include: Lack of symmetry in transmission lines, large single-phase loads, and unbalanced or overloaded transformers. A motor should never be operated when a phase imbalance in supply is greater than 2%.

Perf orm the follo wing steps to determine the percentage of voltage imbalance:

1. Measure the line voltages of your 3-phase

Example

power supply where it enters the building and at a location that will only be dedicated to the

AB = 451V BC = 460V AC = 453V

unit installation. (at the units circuit protection or disconnect).

2. Determine the average voltage in the power supply.

In this example, the measured line voltages were 451, 460, and 453. The aver age would be 454 volts (451 + 460 + 453 = 1,364 / 3 = 454).

3. Determine the maximum deviation:

CAUTION:

To avoid personal injury or property damage, make sure the motor leads do not come into contact with any uninsulated metal components of the unit.

1. Shut off all electrical power to the unit and remove the blower panel. Locate the orange, red and blue wires

terminated to the blower motor. NOTE: The orange wire controls cooling operation while the red wire controls heating operation. The blue wire controls fan-only

operation.

2. V erify the required speed from the airﬂ ow data found in Table 10. Place appropriate wire on the correct motor speed tap for the required airﬂ ow point.

3. The integrated furnace control can be set to a 2 or 3 speed mode. When a G only call is received from the thermostat (indicating a continuous fan mode), the blower will run the heating speed when the 2-SPD mode is selected using the jumper on the control board (factory setting). When 3-SPD mode is selected, the fan only speed may be different than the heating or cooling speed. If no jumper is present, the control defaults to the 2-SPD mode of operation. A call for heating or cooling takes priority over fan only mode

Example:

From the v alues given in step 1, the BC voltage (460V) is the greatest difference in value from the average:

460 - 454 = 6

Highest Value

454 - 451 = 3 454 - 453 = 1

4. Determine percent of voltage imbalance by using the results from steps 2 & 3 in the following equation.

% Voltage Imbalance

=100x

Example:

100

= 1.32%

454

max voltage deviation from average voltage

average voltage

The amount of phase imbalance (1.32%) is satisfactory since the amount is lower than the maximum allowable 2%. Please contact your local electric utility company if your voltage imbalance is more than 2%.

Page 16

Optional Humidistat

An optional humidistat may be installed in the return air duct for humidity control (when needed), maximum system capacity and energy efﬁ ciency. The humidistat senses when humidity in the return air stream is above a preset level and sends a signal to the motor to reduce airﬂ ow. This allows more moisture to be remov ed until the humidity level drops.

NOTE: The packaged heat pump unit is pre-programmed for humidistat operation. Remove the jumper connector between the two terminals marked HUM on the variable speed board.

Install the humidistat in the return air duct as directed in the installation instructions included with the kit. Wire the humidistat through the low-voltage wire entrance in the packaged heat pump unit to the quick-connect terminals marked HUM. Wire the humidistat to open on rise in humidity.

CAUTION:

To avoid personal injury or property damage, make certain that the motor leads cannot come into contact with any uninsulated metal components of the unit.

Check all factory wiring to the units wiring diagram. Inspect the factory wiring connections to be sure none loosened during shipping or installation.

GAS SUPPLY AND PIPING

• All gas piping must be installed in compliance with

local codes and utility regulations. In the absence of local codes the gas line installation must comply with the latest edition of the National Fuel Gas Code ANSI Z223.1 or CAN/CGA B149 Installation Codes.

• Some local codes require the installation of a manual

main shut-off valve and ground joint union external to the furnace (Figure 9). The shut-off v alve should be readily accessible for service and/or emergency use. Consult the local utility or gas supplier for additional requirements regarding placement of the manual main gas shut-off.

• The manifold pressure must be set to the appropriate

value for your installation. Refer to the Manifold Pressure Adjustment section (page 20) for adjustment instructions.

• Gas piping must never run in or through air ducts,

chimneys, gas vents, or elevator shafts.

• Compounds used to seal joints on gas piping m ust

be resistant to the actions of LP propane gas.

• The main gas valve and main power disconnect to

the furnace must be properly labeled b y the installer in case emergency shutdown is required.

• An 1/8 inch NPT plugged tap must be installed in

the gas line immediately upstream of the gas supply connection to the furnace for use when measuring the gas supply pressure. The plug should be readily accessible for service use.

• A drip leg should be installed in the vertical pipe

run to the unit (Figure 9).

This unit only has right side gas entry. When connecting the gas, provide clearance between the gas supply line and the entry hole in the unit’s casing to avoid unw anted noise and/or damage to the unit. A typical gas service hookup is shown in Figure 8.

Table 11 (page 26) lists gas pipe capacities for standard pipe sizes as a function of length in typical applications based on nominal pressure drop in the line.

Leak Check

WARNING:

FIRE OR EXPLOSION HAZARD Never test for gas leaks with an open ﬂ ame. Check all connections using a commercially available soap solution. A ﬁ re or explosion may result causing property damage, personal injury or loss of life. Failure to f ollow the safety warnings exactly could result in serious injury, death or property damage.

After the gas piping to the unit is complete, all connections must be tested for gas leaks. This includes pipe connections at the main gas valve, emergency shutoff valve and other gas connectors. A soap and water solution can be applied on each joint or union using a small paintbrush. If any bubbling is observed, the connection is not sealed adequately and must be retightened. Repeat the tightening and soap check process until bubbling ceases.

• If pressure testing the gas supply lines at pressures

greater than 1/2 psig (14 inches WC), the unit must be disconnected from the gas supply piping system to prevent damage to the gas valve.

• If the test pressure is less than or equal to 1/2 psig

(14 inches WC), the unit must be isolated from the gas supply line by closing the manual shut-off v alve.

High Altitude Conversion

Conversion of this unit must be performed by qualiﬁ ed service personnel, using only approved parts. All installations must be made in accordance with the National Fuel Gas Code and/or local jurisdiction codes.

WARNING:

The reduction of input rating necessary for high altitude installation may only be accomplished with factory supplied oriﬁ ces. Do not attempt to drill out oriﬁ ces in the ﬁ eld. Improperly drilled orifices may cause fire, explosion, carbon monoxide poisoning, personal injury or death.

High altitude conversion can be ﬁ eld performed by a simple adjustment of manifold pressure or a change of the oriﬁ ces (if necessary) as described on page 20. The

changes required depend on the installation altitude and the heating value of the gas (based on sea level) which can be obtained from your local gas utility. The heating value of gas at high altitude is alwa ys low er than the sea level heating value. The heating values listed in Tables 6 & 7 (page 20) are based on sea level values.

If installing this unit above 2,000 f eet, the input rate must be reduced 4% per 1,000 feet of altitude (Example: 12% at 3,000 feet, 16% at 4,000 feet, etc). NOTE: Deration is necessary to compensate for low atmospheric pressure at high altitudes.

For altitudes between 5,000 and 10,000 feet above sea level, the unit can be con verted by adjusting the furnace manifold pressure. See T ables 6 or 7 for the correct manifold pressure settings.

LP/Propane Gas Conversion

W ARNING:

This unit was equipped at the factory for use with natural gas only. A special kit, supplied by the manufacturer , is required to con vert the unit to operate on LP/propane gas. F ailure to use the proper conver sion kit can cause ﬁ re, explosion, property damage, carbon monoxide poisoning, personal injury, or death.

Conversion of this equipment to LP/Propane gas must be made by qualiﬁ ed service personnel, using approved factory parts. Conversion to LP can be accomplished by replacing the natural gas oriﬁ ces with the appropriate LP/ Propane oriﬁ ces and then adjusting the manifold pressure (page 20). altitude) is detailed in the installation instructions provided with the conversion kit. Please follow the instructions provided in each kit. Approved conversion kits are:

• The United States LP/Propane Gas Sea Level and High Altitude Conversion Kit is f or LP/propane conversion in the United States at altitudes between zero and 10,000 ft. above sea level.

• The Canadian LP/Propane Gas Sea Level and High Altitude Conversion Kit is for LP/propane conversions in Canada at altitudes between zero and 4,500 ft. above sea level.

For installations between zero and 4,999 ft. above sea level, a #54 drill size oriﬁ ce should be used. Installations 5,000 ft. above sea level require a # 55 drill size oriﬁ ce. Table 7 (page 20) lists the correct oriﬁ ce size to use at different altitudes.

After changing the oriﬁ ces, it is required that you measure the gas input rate by clocking the gas meter and using the local gas heating value. See Verifying and Adjusting the Firing Rate section on page 19.

Start-Up Procedure

WARNING:

If this unit is equipped with crankcase heaters, allow 24 hrs for heating of the refrigerant compressor crankcase prior to start up or anytime the power has been removed for more than 12 hrs. Failure to comply may result in damage or cause premature failure of the system.

• Check all electrical wiring for loose connections and tighten as required.

• Check unit for return air ﬁ lters and condensate trap.

• Close all electrical disconnects to energize the system.

Air Circulation Leave the thermostat system mode on OFF, and set the

fan mode to ON. Blower should run continuously. Check the air delivery at the supply registers and adjust register openings for balanced air distribution. Examine ductwork for leaks or obstruction if insufﬁ cient air is detected. Set the thermostat fan mode to AUTO. The blower should stop running.

System Cooling

1. Set the thermostat’s system mode to COOL and the fan mode to AUTO. Gradually lower the thermostat temperature setpoint below room temperature and verify the compressor, fan and indoor blower energize.

2. Feel the air being circulated by the indoor blower and verify that it is cooler than ambient temperature. Listen for any unusual noises. If unusual sounds occur, determine the source of the noise and correct as necessary.

3. Allo w the cooling system to operate for sev eral minutes and then set the temperature selector above room temperature. Verify the fan and compressor cycle off with the thermostat. NOTE: The blower will also stop after an 85 - 90 second delay.

System Heating

1. Set the thermostat to the lowest setting.

2. Follow the procedures given on the operating instruction label, this manual or attached inside the louvered control access panel.

3. Set the thermostat above room temper ature and verify the Operating Sequence. See page 20.

4. Verify that the compressor and outdoor fan motor are not energized.

5. After the unit has run for approximately ﬁ ve minutes, set the thermostat below room temperature and verify the shutdown sequence; steps 10 -12 in the Oper ating Sequence section (page 20).

Verifying and Adjusting Temperature Rise

Verify the temperature rise through the unit is within the range speciﬁ ed on the unit data label. Temperature rises outside the speciﬁ ed range could result in premature heat exchanger failure.

1. Place thermometers in the return and supply air stream

as close to the unit as possible. The thermometer on the supply air side must be shielded against direct radiation from the heat exchanger to avoid false readings.

2. Adjust all registers and duct dampers to the desired

position. Run the unit for 10 to 15 minutes before taking any temperature readings. The temperature rise is the difference between the supply and return air temperatures.

NOTE: F or typical duct systems, the temperature rise will fall within the range speciﬁ ed on the data label (with the blower speed at the f actory recommended setting) shown in T able 10 (page 25). If the measured temperature rise falls outside the speciﬁ ed range, it may be necessary to change the blower speed. Lowering the blower speed increases the temperature rise and a higher speed decreases the temperature rise.

The unit is equipped with a variable speed motor . Speed selection is made by moving the leads on the blo wer motor terminal block. The speed taps for adjusting the motor speed are shown in the unit wiring diagram or Figures 12 & 13 (pages 28 - 29). Ref er to the Blo wer Speed Section (page 15) for additional information.

Page 19

The integrated control starts the circulating air blower 30 seconds after the gas valve is opened. The control is factory wired to turn the blower motor off 135 seconds after the gas valve is closed. NOTE: The heating blower off delay is factory set at 90 seconds. An additional 45 second off delay is programmed into the X-13 blower motor for a total of 135 seconds.

3. Remove the close-off plate immediately after the overtemperature limit control opens. If the unit operates for more than four minutes with no return air, set the thermostat below room temperature, shut off power to the unit, and replace the over-temperature limit control.

Verifying Burner Operation

Verifying and Adjusting Firing Rate

CAUTION:

Do not re-drill the burner oriﬁ ces. If the oriﬁ ce size must be changed, use only new oriﬁ ces.

The ﬁ ring rate must be veriﬁ ed for each installation to prevent over-ﬁ ring of the furnace. The ﬁ ring rate must not exceed the rate shown on the unit data label. To determine the ﬁ ring rate, follow the steps below:

1. Obtain the gas heating value (HHV) from the gas supplier.

2. Shut off all other gas ﬁ red appliances.

3. Start the unit in heating mode and allow it to run for at least 3 minutes.

4. Measure the time (in seconds) required for the gas meter to complete one revolution.

5. Convert the time per revolution to cubic feet of gas per hour using Table 13 (page 27).

6. Multiply the gas ﬂ ow rate in cubic feet per hour by the heating value of the gas in Btu per cubic foot to obtain the ﬁ ring rate in Btu per hour. See Example.

Example:

• Time for 1 revolution of a gas meter with a 1 cubic foot dial = 40 seconds.

• From Table 13, read 90 cubic feet gas per hour.

• Local heating value of the gas (obtained from gas supplier) = 1,040 Btu per cubic foot.

• Input rate = 1,040 x 90 = 93,600 Btuh.

7. Adjust the manifold pressure if necessary . See Manif old Pressure Adjustment instructions on page 20. For additional information about elevations above 2,000 feet, see page 17.

Verify Over-Temperature Limit Control Operation

1. Verify the louvered control access panel is in place and that there is power to the unit.

2. Block the return airﬂ ow to the unit by installing a closeoff plate in place of or upstream of the ﬁ lter .

3. Set the thermostat abov e room temperature and v erify the units operating sequence (page 20).

NOTE: The o ver-temper ature limit control should turn off the gas valve within appro ximately four minutes (exact time depends on the efﬁ ciency of the close-off when blocking the return air). The circulating air and combustion blowers should continue to run when the over-temperature limit control switch opens.

W ARNING:

Uninsulated live components are exposed when louvered control access panel is removed.

1. Remove the louvered control access panel and verify there is power to the unit.

2. Set thermostat above room temperature and observe the ignition sequence. NOTE: The b urner ﬂ ame should carry over immediately between all burners without lifting off, curling, or ﬂ oating. The ﬂ ames should be blue, without yellow tips. Make sure the ﬂ ame is drawn into the center of the heat exchanger tube. In a properly adjusted burner assembly, the ﬂ ame bends down and to the right at the end of the heat exchanger tube. The end of the ﬂ ame will be out of sight around the bend.

3. After validating ﬂ ame characteristics, set the thermostat below room temperature and verify the burner ﬂ ame extinguishes completely.

Refrigerant Charging

W ARNING:

R6GD units are shipped fully charged with R-410A refrigerant and ready for installation. When a system is installed according to these instructions, no refrigerant charging is required. If repairs make it necessary for evacuation and charging, it should only be done by qualiﬁ ed, trained personnel thoroughly familiar with this equipment. Some local codes require licensed installation/service personnel to service this type of equipment. Under no circumstances should the owner attempt to install and/or service this equipment. Failure to comply with this warning could result in property damage, personal injury , or death.

CAUTION:

This unit uses refrigerant R-410A. DO NOT use any other refrigerant in this unit. Use of another refrigerant will damage the unit.

The system refrigerant charge can be checked and adjusted through the service por ts provided at the front panel. Use only gauge lines which have a “Schrader” depression device present to actuate the valve. Draw a vacuum on gauge lines to remove air before attaching

Page 20

them to the service ports on the unit. Refrigerant charging must be done by qualiﬁ ed personnel familiar with safe and environmentally responsible refrigerant handling procedures.

Manifold Pressure Adjustment

The manifold pressure must be set to the appropriate value for y our installation. T o adjust the manifold pressure:

1. Obtain the required manifold pressure setting. Use Table 6 for natural gas or Table 7 for LP/propane gas. NOTE: The values listed in the tables are based on sea level v alues. At higher altitudes, the heating v alue of gas is lower than the sea level heating value.

2. Remove the regulator cap. Turn the high fire adjusting screw clockwise to increase the pressure or counterclockwise to reduce the pressure.

3. Replace the regulator cap after adjustments are complete.

OPERATING SEQUENCE

The operating sequences for the heating, cooling, and fan modes are described below. Refer to the ﬁ eld and furnace wiring diagrams (Figures 12 or 13, pages 28 - 29).

Heating Mode

1. On a call for heat, the thermostat closes and applies 24 VAC to terminal W on the control board.

2. The control board checks for continuity on the 24 V A C limit control circuit, over-temperature limit s witch, ﬂ ame rollout switches, and bloc ked vent switch in series. If an open limit is detected, the control board will energize the inducer blower. All other system functions will be inoperable until the limit circuit closes. While the limit is open, the red LED will pulse at a rate of 1 blink per unit time.

3. The furnace control checks for continuity (24 VAC) across the pressure switch. If the pressure switch is closed, the heat mode sequence will not continue. If it remains closed for 10 seconds, the red LED will ﬂ ash 3 times repetitively until the fault condition clears.

4. The inducer energizes (if pressure switch is open).

5. The pressure switch will close. If the pressure switch does not close after 10 seconds, the fault LED will ﬂ ash 2 times and the inducer will continue to run until the switch is closed.

6. The inducer will pre-purge for 30 seconds and then the igniter will start its warm-up as follows:

Initial Pow er up: After 30 seconds of igniter w arm-up,

the gas valves (24 VAC) will open. The igniter circuit will stay energized for 3 seconds after the gas valve opens.

After Initial Pow er up: The control has a programmed

adaptive ignition feature which varies the warm-up period as follows: If ignition is successful the warm-up is reduced by 3 seconds on each subsequent call for heat until ignition failure occurs. Upon ignition failure, the warm-up is increased by 3 seconds on the next try . If successful, the timing remains ﬁ xed at this level. In general, whenever ignition f ailure occurs the warm-up interval is increased by 3 seconds on the next try . And if successful, it remains there. Minimum and maximum warm-up time limits are set at 6 and 54 seconds.

7. The fur nace control must prove ﬂ ame via the ﬂ ame sensor 5 seconds after the gas valves open. If ﬂ ame is sensed, burners are on and the igniter cools off. If no ﬂ ame is sensed, the gas valv e closes immediately and the inducer continues to run. A second trial for ignition (step 6) begins. If no ﬂ ame is sensed on the ﬁ fth try for ignition, the furnace control is locked and the red LED will blink 4 times repetitively. The thermostat must be opened for at least ten seconds to reset the furnace control after a lock out. Otherwise , the furnace will attempt another ignition sequence in 1 hour.

Page 21

8. After the gas valve opens (30 seconds), the blower will ramp to the selected airﬂ ow and continues to run.

9. When the thermostat has been satisﬁ ed, the W terminal on the integrated control is de-energized.

10. The gas valve circuit is de-energized and the gas

vallve closes.

11. The inducer motor will continue to run for the post

purge period of 25 seconds.

12. The main blower will continue to run for the BLO WER

OFF delay of 135 seconds.

13. After the BLOWER OFF timer has been satisﬁ ed, the

integrated control de-energizes the main circulating blower circuit.

Cooling Mode

1. On a call f or cooling, the thermostat closes and applies 24 V AC to the green and y ellow leads in the low voltage area.

2. The green lead applies 24VAC to the G terminal of the integrated control, energizing the main circulating blower circuit at the cooling speed.

3. The yellow lead applies 24VAC to the contactor.

4. When the thermostat is satisﬁ ed, the contactor and integrated control de-energize.

5. The circulating blower motor de-energiz es after a 8590 second delay.

Fan Mode

1. On a call for fan operation, the thermostat applies 24 V AC to the green lead connected to the G terminal of the integrated control.

2. The circulating blower is energized immediately at the heating speed if 2-SPD is selected or fan only speed if 3-SPD is selected on the control. NOTE: If a call for heat occurs, the circulating blower de-energiz es prior to normal heating cycle.

COMPONENT FUNCTIONS

Flame Roll-Out Control

The ﬂ ame roll-out control acts to verify that the burner ﬂ ame is being drawn into the heat exchanger tubes. If the burner ﬂ ame is not being dra wn into the heat exchanger tubes, the roll-out control will open within sev eral seconds and the integrated control diagnostic light will ﬂ ash one time. The circulating air blower and combustion blower will continue to operate if the ﬂ ame roll-out control opens.

Flame Sensor

The ﬂ ame sensor acts to prove that ﬂ ame has carried over from the ignitor to the right-most burner . If no ﬂ ame is sensed, the unit will be shut down automatically.

Gas Valve

The gas valve controls the ﬂ ow of gas to the burners in both low and high ﬁ re. When the gas valve is energized it automatically opens and regulates the gas pressure in the manifold.

Pressure Switch

The pressure switch veriﬁ es that the inducer motor is drawing the combustion gases through the heat e xchanger tubes and venting the gases through the vent system.

Over-Temperature Limit Control

The over-temperature limit control prevents the air temperature leaving the unit from exceeding the maximum outlet air temperature. If the limit opens, the integrated control diagnostic will ﬂ ash one time. The circulating air blower and combustion blower will continue to operate if the over-temperature limit control opens.
