FEATURES/BENEFITS
Every compact one-piece unit arrives fully assembled, charged,
tested, and ready to run.
All ignition components are contained in the compact integrated
gas controller which is easily accessible for servicing. The IGC
control board provides built-in diagnostic capability. A
light-emitting diode simplifies troubleshooting by providing visual
fault notification and required system status confirmation.
The IGC also contains an exclusive anti-cycle protection for gas
heat operation.
The IGC also contains burner control logic for accurate and
dependable gas ignition. The LED is visible without removing the
unit control box access panel. The IGC also maximizes heating
efficiency by controlling evaporator-fan on and off delays.
Tubular, dimpled gas heat exchangers optimize heat transfer for
improved efficiency. The tubular design permits hot gases to
make multiple passes across the path of the supply air. The
dimpled design creates a turbulent gas flow to maximize heating
efficiency.
The efficient in-shot burners and all ignition components are
contained in an easily removable, compact assembly.
The extra thick heat exchanger coating provides corrosion
resistance and ensures long life.
The inducer fan draws hot combustion gas through the heat
exchanger at the optimum rate for the most effective heat
transfer. The heat exchanger operates under negative pressure,
preventing flue gas leakage into the indoor supply air.
The 30-second fan delay prevents cold air from entering the
supply duct system when the conditioned space is calling for
heat to maximize efficiency.
The direct-spark ignition system saves operating expense
compared to pilot ignition systems.
All standard units are designed for natural gas, but an accessory
propane conversion kit is available.
All units have a flame rectification sensor to quickly sense the
burner flame and ignite burners almost immediately. Fast
shutdown is a certainty since the sensor reacts quickly to any
flame outage or system failure.
QUIET, EFFICIENT OPERATION AND
DEPENDABLE PERFORMANCE
Compressors have vibration isolators for quiet operation.
Efficient fan and motor design permits operation at low sound
levels.
Unit sizes 090−180 offer lower utility costs through part-load
operation using 2 stages of cooling.
Quiet and efficient operation is provided by belt-driven
evaporator fans. The belt-driven evaporator-fan is equipped with
variable-pitch pulleys which allow adjustment within the rpm
ranges of the factory-supplied pulleys.
Increased operating efficiency is achieved through computerdesigned coils featuring staggered internally enhanced copper
tubes. Fins are ripple-edged for strength, lanced, and double
waved for higher heat transfer.
DURABLE, DEPENDABLE CONSTRUCTION
Designed for durability in any climate, the weather-resistant
cabinets are constructed of galvanized steel and bonderized,
and all exterior panels are coated with a prepainted baked
enamel finish. The paint finish is non-chalking, and is capable of
withstanding ASTM (American Society for Testing and Materials)
B117 500-hour Salt Spray Test. All internal cabinet panels are
primed, permitting longer life and a more attractive appearance
for the entire unit.
In addition, all size 072−120 units are designed with a single,
continuous top piece to eliminate any possible leaks at seams or
gasketing. Totally enclosed condenser-fan motors and

EASY INSTALLATION AND CONVERSION
All Units are Shipped in the Vertical Duct Configuration for
fit-up to standard roof curbs.
All units feature a base rail design with forklift slots and rigging
holes for easier maneuvering. Durable packaging protects all
units during shipment and storage.
The units can be easily converted from a vertical to a horizontal
duct configuration by relocating the panels supplied with the unit
(size 072−120 only).
To Convert 072−120 Units from vertical to horizontal discharge,
simply relocate 2 panels. The same basic unit can be used for a
variety of applications and can be quickly modified at the jobsite.
To Convert 155−180 Units from vertical to horizontal discharge,
use the optional horizontal supply/return adapter roof curb
(PGH155,180).
Convenient Duct Openings in the unit basepans permit
side-by-side or concentric duct connections without requiring
internal unit modification.
NOTE: On units using horizontal supply and return, the
accessory barometric relief or power exhaust MUST be installed
on the return ductwork.
Thru-The-Bottom Service Connection Capability comes
standard with the rooftop unit to allow power and control wiring and
gas connections to be routed through the unit’s basepan, thereby
minimizing roof penetrations (to prevent water leaks).
(Thru-the-bottom gas connection requires thru-the-bottom
accessory kit.) Power, gas and control connections are made on
the same side of the unit to simplify installation.
The Non-Corrosive Sloped Condensate Drain Pan (Size
072−120) permits either an external horizontal side condensate
drain (outside the roof curb) or an internal vertical bottom drain
(inside the roof curb). Both options require an external,
field-supplied P-trap.
Standard 2-in. Throwaway Filters are easily accessed through
a removable panel located above the air intake hood. No tools
are required to change unit filters.
Belt-Driven Evaporator-Fan Motors allow maximum on-site
flexibility without changing motors or drives.
Low Voltage Wiring Connections are easily made thanks to
the large terminal board which is located for quick, convenient
access.
In addition, color-coded wires permit easy tracing
and diagnostics.
PROVEN COMPRESSOR RELIABILITY
Design techniques feature computer-programmed balance
between compressor, condenser, and evaporator. Hermetic
compressors are equipped with compressor overcurrent and
overtemperature protection to ensure dependability.
All units have piston (072−120) or TXV (thermostatic expansion
valve) metering device (155−180) which precisely controls
refrigerant flow, preventing slugging and flood-back, while
maintaining optimum unit performance. Refrigerant filter driers
are standard.
INTEGRATED ECONOMIZERS AND
OUTDOOR-AIR DAMPERS
Available as accessories, economizers and manual outdoor-air
dampers introduce outdoor air which mixes with the conditioned
air, improving indoor-air quality and often reducing energy
consumption.
During a first stage call for cooling, if the outdoor-air temperature
is below the economizer control changeover set point, the
Specifications subject to change without notice.
521 51 1101 04
mixed-air sensor modulates the economizer outdoor-air damper
open to take advantage of free cooling provided by the outside
air. When second-stage cooling is called for, the compressor is
energized in addition to the economizer. If the outdoor-air
temperature is above the changeover set point, the first stage of
compression is activated and the economizer damper stays at
minimum position.
All economizers incorporate a parallel blade, gear-driven
damper system for efficient air mixing and reliable control. In
addition, the standard damper actuator includes a spring return
to provide reliable closure on power loss. The economizers for
sizes 072−120 are equipped with up to 100% barometric relief
capability for high outdoor airflow operations. Economizers for
unit sizes 155−180 are compatible for vertical or horizontal
return. An optional field-installed barometric relief package is
available for size 155−180 units.
In addition, single-stage power exhaust is available as a
field-installed
accessory
to
help
maintain
proper
building pressure.
For units without economizer, year-round ventilation is enhanced
by a manual outdoor-air damper. On 072−120 units, a 50%
manual damper is available as a field-installed accessory. Unit
sizes 155−180 are equipped with a manual 25% damper.
INDOOR-AIR QUALITY (IAQ)
Sloped condensate pans minimize biological growth in rooftop
units in accordance with ASHRAE Standard 62. Two-inch filters
provide for greater particle reduction in the return air. The
face-split evaporator coils improve the dehumidification
capability of standard units, maximize building humidity control.

NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:
tldb = tedb –
sensible capacity (Btuh)
1.10 x cfm
tlwb = Wet-bulb temperature corresponding to enthalpy of air leaving
evaporator coil (hlwb)
hlwb = hewb –
total capacity (Btuh)
4.5 x cfm
Where: hewb = Enthalpy of air entering evaporator coil.
3. The SHC is based on 80F edb temperature of air entering evaporator coil. Below 80F edb,
subtract (corr factor x cfm) from SHC.
Above 80_F edb, add (corr factor x cfm) to SHC.
Correction Factor = 1.10 x (1 – BF) x (edb – 80).

*Derating of the unit is not required unless the heating value of the gas exceeds the values listed in
the table above, or if the elevation exceeds 6000 ft. Derating conditions must be 4% per thousand ft
above 2000 ft. For example, at 4000 ft, if the heating value of the gas exceeds 1000 Btu/ft3, the unit
will require a 16% derating. For elevations above 6000 ft, the same formula applies. For example, at
7000 ft, the unit will require a 28% derating of the maximum heating value per the National Fuel Gas
Code.
IMPORTANT: Local utility companies may be reducing heat content of gas at altitudes above 2000
ft. If this is being done, changing spuds may not be required.

2. The EPACT (Energy Policy Act of 1992) regulates energy requirements for specific types of
indoor fan motors. Motors regulated by EPACT include any general purpose, T‐frame
(three‐digit, 143 and larger), single‐speed, foot mounted, polyphase, squirrel cage induction
motors of NEMA (National Electrical Manufacturers Association) design A and B, manufactured
for use in the United States. Ranging from 1 to 200 Hp, these continuous‐duty motors operate
on 230 and 460 volt, 60 Hz power. If a motor does not fit into these specifications, the motor
does not have to be replaced by an EPACT‐compliant energy‐efficient motor. Variable‐speed
motors are exempt from EPACT compliance requirements. Therefore, the indoor fan motors for
PGH036‐120 units are exempt from these requirements.

NOTE: AXB power exhaust is wired single phase, drop third leg when installing.
NOTE: If a single power source is to be used, size wire to include power exhaust MCA and MOCP.
Check MCA and MOCP when power exhaust is powered through the unit. Determine the new MCA
including the power exhaust using the following formula:
MCA New = MCA unit only + MCA of Power Exhaust
MCA New = 28.9 amps + 1.6 amps = 30.5 amps
If the new MCA does not exceed the published MOCP, then MOCP would not change. The MOCP in
this example is 35 amps and the MCA New is below 35; therefore the MOCP is acceptable. If “MCA
New” is larger than the published MOCP, raise the MOCP to the next larger size. For separate
power, the MOCP for the power exhaust will be 15 amps per NEC.

mounted on the evaporator fan housing to control
economizer operation to a supply air temperature of 55°
F.
j. The economizer shall have a gear−driven parallel blade
design.
k. Economizer controller shall provide control of internal
building pressure through its accessory power exhaust
function. Factory set at 100%, with a range of 0% to
100%.
l. Economizer Controller Occupied Minimum Damper
Position Setting maintains the minimum airflow into the
building during occupied period providing design
ventilation rate for full occupancy (damper position during
heating). A remote potentiometer may be used to
override the set point.
m. Economizer Controller Unoccupied Minimum Damper
Position Setting − The economizer damper shall be
completely closed when the unit is in the occupied mode.
521 51 1101 04
n. Economizer Controller IAQ/DCV Maximum Damper
Position Setting − Setting the maximum position of the
damper prevents the introduction of large amounts of hot
or cold air into the space. This position is intended to
satisfy the base minimum ventilation rate.
o. Economizer controller IAQ/DCV control modulates the
outdoor−air damper to provide ventilation based on the
optional 2 to 10 vdc CO2 sensor input.
p. Compressor lockout sensor (opens at 35° F, closes at 50°
F).
q. Actuator shall be direct coupled to economizer gear,
eliminating linkage arms and rods.
r. Control LEDs:
1. When the outdoor−air damper is capable of
providing free cooling, the “Free Cool” LED shall
illuminate.
2. The IAQ LED indicates when the module is on the
DCV mode.
3. The EXH LED indicates when the exhaust fan
contact is closed.
s. Remote Minimum Position Control − A field−installed
accessory remote potentiometer shall allow the
outdoor−air damper to be opened or closed beyond the
minimum position in the occupied mode for modified
ventilation.

tldb = tedb –
BYPASS
FACTOR
(BF)
sensible capacity (Btuh)
1.10 x cfm
tlwb = Wet-bulb temperature corresponding to enthalpy of air leaving evaporator coil (hlwb)
hlwb = hewb –
total capacity (Btuh)
4.5 x cfm
Where: hewb = Enthalpy of air entering evaporator coil
3. The SHC is based on 80F edb temperature of air entering evaporator coil. Below 80F edb,
subtract (corr factor x cfm) from SHC.
Above 80_F edb, add (corr factor x cfm) to SHC.

*Standard low-medium static drive range is 895 to 1147 rpm. Other rpms require a field-supplied
drive.
Refer to this page for general Fan Performance Data notes.
NOTES:
1. Field‐supplied motor required.
2. Maximum continuous bhp for the standard motor is 3.13 (for 208/230 and 460‐v units) or
3.38 (for 575‐v units). The maximum continuous watts is 2700 (for 208/230 and 460‐v
units) or 3065 (for 575‐v units). Do not adjust motor rpm such that motor maximum bhp
and/or watts is exceeded at the maximum operating cfm. See Evaporator Fan Motor
Data tables for more information.
3. Fan performance is identical for horizontal discharge applications using a horizontal
adapter curb.

*Standard low-medium static drive range is 895 to 1147 rpm. Other rpms require a field-supplied
drive.
Refer to General Fan Performance Data notes.
NOTES:
1. Field-supplied motor required.
2. Maximum continuous bhp for the standard motor is 3.13 (for 208/230 and 460‐v units)
or 3.38 (for 575‐v units). The maximum continuous watts is 2700 (for 208/230 and
460‐v units) or 3065 (for 575‐v units). Do not adjust motor rpm such that motor
maximum bhp and/or watts is exceeded at the maximum operating cfm. See
Evaporator Fan Motor Data tables for more information.
3. Fan performance is identical for horizontal discharge applications using a horizontal
adapter curb.

*Derating of the unit is not required unless the heating value of the gas exceeds the values listed in
the table above, or if the elevation exceeds 6000 ft. Derating conditions must be 4% per thousand ft
above 2000 ft. For example, at 4000 ft, if the heating value of the gas exceeds 1000 Btu/ft3, the unit
will require a 16% derating. For elevations above 6000 ft, the same formula applies. For example, at
7000 ft, the unit will require a 28% derating of the maximum heating value per the National Fuel Gas
Code.
IMPORTANT: Local utility companies may be reducing heat content of gas at altitudes above 2000
ft. If this is being done, changing spuds may not be required.

CONTROLS
OPERATING SEQUENCE, SIZE 072−120 UNITS
Cooling, Units Without Economizer
When thermostat calls for cooling, terminals G and Y1 are
energized. The indoor-fan contactor (IFC) and compressor
contactor are energized and indoor-fan motor, compressor, and
outdoor fan starts. The outdoor-fan motor runs continuously
while unit is cooling.
For units with 2 stages of cooling, if the thermostat calls for a
second stage of cooling by energizing Y2, compressor contactor
no. 2 (C2) is energized and compressor no. 2 starts.
Heating, Units Without Economizer
When the thermostat calls for heating, terminal W1 is energized.
To prevent thermostat short-cycling, the unit is locked into the
Heating mode for at least 1 minute when W1 is energized. The
induced-draft motor is energized and the burner ignition
sequence begins. The indoor (evaporator) fan motor (IFM) is
energized 45 seconds after a flame is ignited. On units equipped
for two stages of heat, when additional heat is needed, W2 is
energized and the high-fire solenoid on the main gas valve
(MGV) is energized. When the thermostat is satisfied and W1 is
deenergized, the IFM stops after a 45-second time-off delay.
If there is a further demand for cooling (cooling second stage —
Y2 is energized), then the control will bring on compressor stage
1 to maintain the mixed-air temperature set point. The
Economizer damper will be open at maximum position.
Economizer operation is limited to a single compressor.
Heating, Units With Economizer
NOTE: The units have 2 stages of heat.
When the thermostat calls for heating, power is sent to W1 on
the IGC (integrated gas unit controller) board. An LED
(light-emitting diode) on the IGC board will be on during normal
operation. A check is made to ensure that the rollout switch and
limit switch are closed and the induced-draft motor is running.
The induced-draft motor is then energized, and when speed is
proven with the hall effect sensor on the motor, the ignition
activation period begins. The burners will ignite within
5 seconds.
If the burners do not light, there is a 22-second delay before
another 5-second attempt. If the burners still do not light, this
sequence is repeated for 15 minutes. After the 15 minutes have
elapsed, if the burners still have not lit, heating is locked out. To
reset the control, break 24-v power to the thermostat.
When ignition occurs the IGC board will continue to monitor the
condition of the rollout and limit switches, the hall effect sensor,
as well as the flame sensor. If the unit is controlled through a
room thermostat set for fan auto., 45 seconds after ignition
occurs, the indoor-fan motor will be energized (and the
outdoor-air dampers will open to their minimum position). If for
some reason the overtemperature limit opens prior to the start of
the indoor fan blower, on the next attempt, the 45-second delay
will be shortened to 5 seconds less than the time from initiation
of heat to when the limit tripped. Gas will not be interrupted to
the burners and heating will continue. Once modified, the fan on
delay will not change back to 45 seconds unless power is reset
to the control.
When additional heat is required, W2 closes and initiates power
to the second stage of the main gas valve. When the thermostat
is satisfied, W1 and W2 open and the gas valve closes,
interrupting the flow of gas to the main burners. If the call for W1
lasted less than 1 minute, the heating cycle will not terminate
until 1 minute after W1 became active. If the unit is controlled
through a room thermostat set for fan auto., the indoor-fan motor
will continue to operate for an additional 45 seconds then stop
(and the outdoor-air dampers will close). If the overtemperature
limit opens after the indoor motor is stopped within 10 minutes of
58
W1 becoming inactive, on the next cycle the time will be
extended by 15 seconds. The maximum delay is 3 minutes.
Once modified, the fan off delay will not change back to 45
seconds unless power is reset to the control.
When the thermostat is satisfied and W1 and W2 are
deenergized, the IFM continues to run and the economizer
damper then moves to the minimum position.
OPERATING SEQUENCE, PGH155,180
Cooling, Units Without Economizer
When thermostat calls for cooling, terminals G and Y1 are
energized. The indoor (evaporator) fan contactor (IFC) and
compressor contactor no. 1 (C1) are energized, and
evaporator-fan motor (IFM), compressor no. 1 and condenser
fan(s) start. The condenser-fan motor(s) runs continuously while
unit is cooling. When the thermostat calls for a second stage of
cooling by energizing Y2, compressor contactor no. 2 (C2) is
energized and compressor no. 2 starts.
Heating, Units Without Economizer
When the thermostat calls for heating, power is sent to W on the
IGC (integrated gas unit controller) board. An LED (light-emitting

check is made to ensure that the rollout switch and limit switch
are closed. The induced-draft motor is then energized, and when
speed is proven with the hall effect sensor on the motor, the
ignition activation period begins. The burners will ignite within 5
seconds.
If the burners do not light, there is a 22-second delay before
another 5-second attempt. If the burners still do not light, this
sequence is repeated for 15 minutes. After the 15 minutes have
elapsed, if the burners still have not lit, heating is locked out. To

the overtemperature limit opens after the indoor motor is
stopped within 10 minutes of W1 becoming inactive, on the next
cycle the time will be extended by 15 seconds. The maximum
delay is 3 minutes. Once modified, the fan off delay will not
change back to 45 seconds unless power is reset to the control.
An LED indicator is provided on the IGC to monitor operation.
The IGC is located by removing the side panel and viewing the
IGC through the view port located in the control box access
panel. During normal operation, the LED is continuously on.

CONTROLS (cont.)
Cooling, Units With Economizer
Heating, Units With Economizer
When free cooling is not available, the compressors will be
controlled by the zone thermostat. When free cooling is
available, the outdoor-air damper is modulated by the
Economizer control to provide a 50 to 55F mixed-air
temperature into the zone. As the mixed-air temperature
fluctuates above 55 or below 50F, the dampers will be
modulated (open or close) to bring the mixed-air temperature
back within control.
If mechanical cooling is utilized with free cooling, the outdoor-air
damper will maintain its current position at the time the
compressor is started. If the increase in cooling capacity causes
the mixed-air temperature to drop below 45F, then the
outdoor-air damper position will be decreased to the minimum
position. If the mixed-air temperature continues to fall, the
outdoor-air damper will close. Control returns to normal once the
mixed-air temperature rises above 48F.
If optional power exhaust is installed, as the outdoor-air damper
opens and closes, the power exhaust fans will be energized and
deenergized.
If field-installed accessory CO2 sensors are connected to the
Economizer control, a demand controlled ventilation strategy will
begin to operate. As the CO2 level in the zone increases above
the CO2 set point, the minimum position of the damper will be
increased proportionally. As the CO2 level decreases because of
the increase in fresh air, the outdoor-air damper will be
proportionally closed.
For Economizer operation, there must be a thermostat call for
the fan (G). If the unit is occupied and the fan is on, the damper
will operate at minimum position. Otherwise, the damper will
be closed.
When the Economizer control is in the occupied mode and a call
for cooling exists (Y1 on the thermostat), the control will first
check for indoor fan operation. If the fan is not on, then cooling
will not be activated. If the fan is on, then the control will open
the Economizer damper to the minimum position.
On the initial power to the Economizer control, it will take the
damper up to 21/2 minutes before it begins to position itself. Any
change in damper position will take up to 30 seconds to initiate.
Damper movement from full closed to full open (or vice versa)
will take between 11/2 and 21/2 minutes.
If free cooling can be used as determined from the appropriate
changeover command (switch, dry bulb, enthalpy curve,
differential dry bulb, or differential enthalpy), then the control will
modulate the dampers open to maintain the mixed-air
temperature set point at 50 to 55F.
If there is a further demand for cooling (cooling second stage −
Y2 is energized), then the control will bring on compressor stage
1 to maintain the mixed-air temperature set point. The
Economizer damper will be open at maximum position.
Economizer operation is limited to a single compressor.
NOTE: The units have 2 stages of heat.
When the thermostat calls for heating, power is sent to W1 on
the IGC (integrated gas unit controller) board. An LED
(light-emitting diode) on the IGC board will be on during normal
operation. A check is made to ensure that the rollout switch and
limit switch are closed and the induced-draft motor is running.
The induced-draft motor is then energized, and when speed is
proven with the hall effect sensor on the motor, the ignition
activation period begins. The burners will ignite within
5 seconds.
If the burners do not light, there is a 22-second delay before
another 5-second attempt. If the burners still do not light, this
sequence is repeated for 15 minutes. After the 15 minutes have
elapsed, if the burners still have not lit, heating is locked out. To
reset the control, break 24-v power to the thermostat.
When ignition occurs the IGC board will continue to monitor the
condition of the rollout and limit switches, the hall effect sensor,
as well as the flame sensor. If the unit is controlled through a
room thermostat set for fan auto., 45 seconds after ignition
occurs, the indoor-fan motor will be energized (and the
outdoor-air dampers will open to their minimum position). If for
some reason the overtemperature limit opens prior to the start of
the indoor fan blower, on the next attempt, the 45-second delay
will be shortened to 5 seconds less than the time from initiation
of heat to when the limit tripped. Gas will not be interrupted to
the burners and heating will continue. Once modified, the fan on
delay will not change back to 45 seconds unless power is reset
to the control.
When additional heat is required, W2 closes and initiates power
to the second stage of the main gas valve. When the thermostat
is satisfied, W1 and W2 open and the gas valve closes,
interrupting the flow of gas to the main burners. If the call for W1
lasted less than 1 minute, the heating cycle will not terminate
until 1 minute after W1 became active. If the unit is controlled
through a room thermostat set for fan auto., the indoor-fan motor
will continue to operate for an additional 45 seconds then stop
(and the outdoor-air dampers will close). If the overtemperature
limit opens after the indoor motor is stopped within 10 minutes of
W1 becoming inactive, on the next cycle the time will be
extended by 15 seconds. The maximum delay is 3 minutes.
Once modified, the fan off delay will not change back to 45
seconds unless power is reset to the control.
When the thermostat is satisfied and W1 and W2 are
deenergized, the IFM continues to run and the economizer
damper then moves to the minimum position.
