GENERAL
YORK Model DM, DF and DH units are either single
package cooling units equipped with optional factory
installed electric heaters, or single package gas-fired
central heating furnaces with cooling unit. Both are
designed for outdoor installation on a rooftop or slab.
The units are completely assembled on rigid, permanently attached base rails. All piping, refrigerant
charge, and electrical wiring is factory installed and
tested. The units require electric power, gas connection, duct connections, installation of combustion air
inlet hood, flue gas outlet hoods and fixed outdoor air
intake damper (units without economizer or motorized
damper option only) at the point of installation.
The supplemental electric heaters have nickel-chrome
elements and utilize single point power connection.
The gas-fired heaters have aluminized-steel (or
optional stainless steel) tubular heat exchangers. The
units have spark ignition with proven pilot. All gas heaters are shipped from the factory equipped for natural
gas use, but can be field converted to L.P./ Propane
with Kit Model # 1NP0440 for single stage and Kit
Model # 1NP0485 for 2 stage.

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unless superseded by local codes or gas utility requirements.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.

Maximum capacity of pipe in cubic feet of gas per hour. (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.

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.

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.

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.

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.

1. 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.

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. The job specifications may require
that this balancing be done by someone other than the
equipment installer.

NOTE: The tubes must be inserted and held in a posi-

readings.
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.

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-

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.

GAS HEATING SEQUENCE OF OPERATIONS
(SINGLE STAGE)
When the thermostat calls for heating, the low-voltage
control circuit from “R” to “W1” and “G” is completed,
through the UCB. 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.

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.

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

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

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.

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

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.

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.
