General
YORK® Model ZF units are either single package air
conditioners 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.
These gas-fired heaters have aluminized-steel or optional
stainless steel, tubular heat exchangers with 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 # 1NP0418. See Gas Heat Application Data Table.

Ductwork
Ductwork should be designed and sized according to the
methods in Manual D of the Air Conditioning Contractors of
America (ACCA) or as recommended by any other recognized
authority such as ASHRAE or SMACNA.
A closed return duct system should be used. This will not
preclude use of economizers or outdoor fresh air intake. The
supply and return air duct connections at the unit should be
made with flexible joints to minimize noise.
The supply and return air duct systems should be designed for
the CFM and static pressure requirements of the job. They
should NOT be sized to match the dimensions of the duct
connections on the unit.
Refer to Figure 5 for bottom air duct openings. Refer to Figure 7
for side air duct openings.
NOTE: It is recommended that, in Canada, the outlet duct be
provided with a removable access panel. It is
recommended that this opening be accessible when
the unit is installed in service, and of a size such that
smoke or reflected light may be observed inside the
casing to indicate the presence of leaks in the heat
exchanger. The cover should be attached in a
manner adequate to prevent leakage.
Figure 9: Roof Curb Dimensions (All Models)
* Supply and Return air (including duct
support rails) as shown, are typical for
Downflow duct applications
For location of Sideflow duct applica-
tions (on back of unit), refer to Unit
Dimension details.

Fixed Outdoor Air Intake Damper
This damper is shipped inside the return air compartment. It is
completely assembled and ready for installation. A damper
baffle inside of the hood is adjustable to provide variable
amounts of outdoor air intake on units that are not provided with
an economizer or a motorized damper option. Refer to the
Fixed Outdoor Damper Figure 12.
Gasketing and mounting screws are provided in a parts bag
attached to the hood assembly. Apply gasketing to the three
flange surfaces on the hood prior to installing the hood. Extend
gasketing 1/4 inch beyond the top and bottom of the two side
flanges to insure adequate sealing.
Adjusting the damper to the desired air flow may be done
before mounting the hood into position or after installation by
removing the front hood panel or the screen on the bottom of
the hood. Damper baffle in position 1 will allow approximately
10% outdoor air flow, position 2 approximately 15% and, to
allow approximately 25%, remove the damper baffle.
On units with bottom return air application install the damper
assembly over the opening in the side return air access panel.
Remove and discard the opening cover and the covering over
the hood mounting holes (used for shipping) before installing.
Secure with the screws provided.
On units with side return air applications, install the damper
assembly on the return air ductwork as close to the unit as
possible. Cut an opening 16 inches high by 18 inches wide in the
ductwork to accommodate the damper. Using the holes in the
hood flanges as a template, drill 9/64 inch diameter (#26 drill)
holes into the ductwork and secure with the screws provided.
Figure 12: Fixed Outdoor Air Damper
Condensate Drain
Plumbing must conform to local codes. Use a sealing compound
on male pipe threads. Install a condensate drain line from the
one-inch NPT female connection on the unit to an open drain.
NOTE: The condensate drain operates in a negative pressure
in the cabinet. The condensate drain line MUST be
trapped to provide proper drainage. See Figure 13.
Figure 13: Condensate Drain
Compressors
The scroll compressor used in this product is specifically
designed to operate with R-410A Refrigerant and cannot be
interchanged.
The compressor also uses a polyolester (POE oil), Mobil 3MA
POE. This oil is extremely hygroscopic, meaning it absorbs water
readily. POE oil can absorb 15 times as much water as other oils
If outdoor air intake will not be required on units with
bottom return air applications, the damper assembly
should still be mounted on the side return air access
panel, per the instructions above, to insure moisture is
not drawn into the unit during operation. The covering
over the mounting holes only need be removed. Do not
remove the opening cover.
This system uses R-410A Refrigerant which operates at
higher pressures than R-22. No other refrigerant may be
used in this system.

designed for HCFC and CFC refrigerants. Take all necessary
precautions to avoid exposure of the oil to the atmosphere.
POE (polyolester) compressor lubricants are known to cause
long term damage to some synthetic roofing materials.
Procedures which risk oil leakage include, but are not limited to,
compressor replacement, repairing refrigerant leaks, replacing
refrigerant components such as filter drier, pressure switch,
metering device or coil.
Units are shipped with compressor mountings which are
factory-adjusted and ready for operation.
Filters
Two-inch filters are supplied with each unit, but units can be
converted easily to four-inch filters. Filters must always be
installed ahead of the evaporator coil and must be kept clean or
replaced with same size and type. Dirty filters will reduce the
capacity of the unit and will result in frosted coils or safety
shutdown. Minimum filter area and required sizes are shown in
Physical Data Table 10.
Power And Control Wiring
Field wiring to the unit, fuses, and disconnects must conform to
provisions of National Electrical Code (NEC), ANSI/NFPA No.
70 – Latest Edition (in U.S.A.), current Canadian Electrical
Code C221, and/or local ordinances. The unit must be
electrically grounded in accordance with NEC and CEC as
specified above and/or local codes.
Voltage tolerances which must be maintained at the
compressor terminals during starting and running conditions are
indicated on the unit Rating Plate and Table 1.
The internal wiring harnesses furnished with this unit are an
integral part of the design certified unit. Field alteration to
comply with electrical codes should not be required. If any of
the wire supplied with the unit must be replaced, replacement
wire must be of the type shown on the wiring diagram and the
same minimum gauge as the replaced wire.
A disconnect must be utilized for these units. Factory installed
disconnects are available. If installing a disconnect (field
supplied or York International® supplied accessory), refer to
Figure 1 for the recommended mounting location.
NOTE: Since not all local codes allow the mounting of a
disconnect on the unit, please confirm compliance with
local code before mounting a disconnect on the unit.
Electrical line must be sized properly to carry the load. USE
COPPER CONDUCTORS ONLY. Each unit must be wired with
a separate branch circuit fed directly from the meter panel and
properly fused.
Refer to Figures 14 and 15 for typical field wiring and to the
appropriate unit wiring diagram mounted inside control doors
for control circuit and power wiring information.
Power Wiring Detail
Units are factory wired for the voltage shown on the unit
nameplate. Refer to Electrical Data Table 9 to size power
wiring, fuses, and disconnect switch.
Power wiring is brought into the unit through the side of the unit
or the basepan inside the curb.
Do not leave the system open to the atmosphere. Unit
damage could occur due to moisture being absorbed by
the POE oil in the system. This type of oil is highly
susceptible to moisture absorption
Exposure, even if immediately cleaned up, may cause
embrittlement (leading to cracking) to occur in one year
or more. When performing any service that may risk
exposure of compressor oil to the roof, take precautions
to protect roofing.
Do not loosen compressor mounting bolts.
Make sure that panel latches are properly positioned on
the unit to maintain an airtight seal.
Avoid damage to internal components if drilling holes for
disconnect mounting.
When connecting electrical power and control wiring to
the unit, water-proof connectors must be used so that
water or moisture cannot be drawn into the unit during
normal operation. The above water-proofing conditions
will also apply when installing a field supplied disconnect
switch.

Optional Gas Heat
These gas-fired heaters have aluminized-steel or optional
stainless steel, tubular heat exchangers with spark ignition with
proven pilot.
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 CSA-B149.1 (in Canada) should be
followed in all cases unless superseded by local codes or gas
utility requirements. Refer to the Pipe Sizing Table 13. The
heating value of the gas may differ with locality. The value
should be checked with the local gas utility.
NOTE: There may be a local gas utility requirement specifying
a minimum diameter for gas piping. All units require a
one-inch pipe connection at the entrance fitting.
Figure 16: External Supply Connection External Shut-Off
Figure 17: Bottom Supply Connection External Shut-Off
NOTE: Maximum capacity of pipe in cubic feet of gas per hour
based upon a pressure drop of 0.3 inch W.C. and 0.6
specific gravity gas.
Gas Connection
The gas supply line can be routed within the space and roof curb,
exiting through the unit’s basepan. Refer to Figure 5 for the gas
piping inlet location. Typical supply piping arrangements are
shown in Figures 16 and 17. All pipe nipples, fittings, and the gas
cock are field supplied.
Gas piping recommendations:
1. A drip leg and a ground joint union must be installed in the
gas piping.
2. Where required by local codes, a manual shut-off valve
must be installed outside of the unit.
3. Use wrought iron or steel pipe for all gas lines. Pipe dope
should be applied sparingly to male threads only.

Natural gas may contain some propane. Propane is an
excellent solvent and will quickly dissolve white lead and
most standard commercial compounds. A special pipe
dope must be used when assembling wrought iron or
steel pipe. Shellac based compounds such as Gaskolac
or Stalastic, and compounds such as Rectorseal #5,
Clydes’s or John Crane may be used.
