These instructions cover minimum requirements and conform to existing national standards and safety codes. In some instances, these instructions exceed certain local codes and ordinances, especially those that may not have kept up with changing residential construction practices. We require
these instructions as a minimum for a safe installation.
INTRODUCTION
The PYIP and PY2P units (See Fig. I) are fully self-contained, combination Category 1gas heating/electric cooling units designed for outdoor installation (See Fig. 2 and 3 for unit dimensions). All unit sizes have return and discharge openings for both horizontal and downflow
configurations, and are factory shipped with all downflow duct openings covered. Units may be installed either on a rooftop, a cement slab, or directly on the grounst if local codes permit (See Fig. 4 for roof curb dimensions).
Models with an N in the thirteenth position of the model number are dedicated Low NO×units designed for California installations. These models meet the California maximum oxides of nitrogen (NOx) emissions requirements of 40 nanograms/joule or less as shipped from the
factory and must be installed in California Air Quality Management Districts where a Low NO× rule exists.
RECEIVING AND INSTALLATION
PROCEDURE I--CHECK EQUIPMENT
A. IDENTIFY UNIT
The unit model number and serial number are stamped on unit identification plate. Check this information against shipping papers and job data. Verify unit voltage and amperage requirements listed on unit rating plate agree with power supply provided to unit.
B. INSPECT SHIPMENT
inspect for shipping damage while Emitis still on shipping pallet. If unit appears to be damaged or is torn loose from its anchorage, have it examined by transportation inspectors before removal. Forward claim papers directly to transportation company. Manufacturer is not responsible for any
damage incurred in transit. Check all items against shipping list. immediately notify the nearest distributor if any item is missing.
To prevent loss or damage, leave all parts in original packages until installation.
C. INSTALLATION
1. Remove unit from shipping carton. Leave top shipping skid on the unit as a spreader bar to prevent the rigging straps from damaging the unit. if the wood skid is not available, use a spreader bar of sufficient length to protect unit from damage.
2. Position the lifting bracket assembly around the base of the unit. Be sure the strap does not twist.
3. Place each of the 4 metal lifting brackets into the rigging holds in the composite pan.
4. Thread lifting bracket strapping around bottom perimeter of unit as follows: a. Open lever of tension buckle (ratchet type).
b. Feed strapping through tension buckle as shown in Fig. 7A. c. Pull strapping through tension buckle unit taut.
d. Snap lever down to lock strap in tension buckle. To release strapping, squeeze safety latch, lift lever, and pull webbing outward.
5. Tighten the tension buckle until it is taut. Lifting brackets must be secure in the rigging holds.
6. Attach field-supplied clevis or hook of sufficient strength to hole in the lifting bracket (See Fig. 7B).
7. Attach the 2 safety straps directly to the clevis or hook at the 4 rigging brackets. DO NOT attach the safety straps to the lifting brackets (See Fig. 7B).
8. Position lifting point directly over the unit's center of gravity.
9. Lift unit. When unit is directly over the roof curb, remove the 2 safety straps. Lower the equipment onto the roof curb.
PROCEDURE 2--PROVIDE UNIT SUPPORT
A. ROOFCURB
install accessory roof curb in accordance with instructions shipped with curb (See Fig. 4 for roof curb dimensions), install insulation, cant strips, roofing, and flashing. Ductwork must be attached to curb.
IMPORTANT: The gasketing of the unit to the roof curb is critical for a watertight seal. Install gasketing material supplied with the roof curb. improperly applied gasketing can also result in air leaks and poor unit performance. Curb should be level to within 1/4 in. This is necessary for unit drain to function properly. Refer to accessory roof curb installation instructions for additional information as required.
B. SLAB MOUNT
Place the unit on a solid, level concrete pad that is a minimum of 4 in. thick with 2 in. above grade. The slab should be flush on the compressor end of the unit (to allow condensate drain installation) and should extend 2 in. on the three remaining sides of the unit (See Fig. 6). Do not secure the unit to the slab except when required by local codes.
C. GROUND MOUNT
The unit may be installed either on a slab or placed directly on the ground if local codes permit. Place the unit on level ground prepared with gravel for condensate discharge.
PROCEDURE 3--FIELD FABRICATE DUCTWORK
Secure all ducts to roof curb and building structure on vertical discharge units. Do not connect ductwork to unit. For horizontal applications, unit is provided with flanges on the horizontal openings. Installation of flexible duct connector is recommensted to prevent transmission of vibration
and/or noise to structure. All ductwork should be secured to the flanges, insulate and weatherproof all external ductwork, joints, and roof openings with counter flashing and mastic in accordance with applicable codes.

PROCEDURE 5--RIG AND PLACE UNIT Fig. 7B--Suggested Rigging
CAUTION: When installing the unit on a rooftop, be sure the roof will support the additional weight.
Use spreader bars or crate top when rigging the unit. The units must be rigged for lifting (See Fig. 6). Refer to Table 1 and 2 for operating weight.
Use extreme caution to prevent damage when moving the unit. Unit must remain in an upright position during all rigging and moving
operations.The unit must be level within I/4" for proper condensate drainage; therefore, the ground-level pad or accessory roof curb must be level
before setting the unit in place. When a field-fabricated support is used, be sure that the support is level and properly supports the unit. Lifting point should be directly over the center of gravity for the unit.
PROCEDURE 6--CONNECT CONDENSATE DRAIN
NOTE: When installing condensate drain connection be sure to comply with local codes and restrictions,
Models PYIP and PY2P dispose of condensate water through a 3/4 in. NPT fitting which exits through the compressor access panel (See Fig. 2 and 3 for location).
Condensate water can be drained directly onto the roof in rooftop installations (where permitted) or onto a gravel apron in ground-level installations. Install a field-supplied condensate trap at end of condensate connection to ensure proper drainage. Make sure that the outlet of the
trap is at least 1 in. lower than the drain pan condensate connection to prevent the pan from overflowing (See Fig. 8). Prime the trap with water. When using a gravel apron, make sure it slopes away from the unit, if the installation requires draining the condensate water away from the unit, install a 2-in. trap at the condensate connection to ensure proper
drainage (See Fig. 8). Make sure that the outlet of the trap is at least I in. lower than the drainpan condensate connection. This prevents the pan fi'om overflowing. Prime the trap with water, Connect a drain tube - using a minimum of 3/4-in. PVC or 3/4-in. copper pipe (all field-supplied) - at the outlet end
of the 2-in. trap. Do not undersize the tube. Pitch the drain tube downward at a slope of at least 1-in. for every 10 fl of horizontal run. Be sure to check the drain tube for leaks.
PROCEDURE 7--INSTALL FLUE HOOD
The flue hood assembly is shipped screwed to the coil panel in the indoor blower compartment. Remove the service access panel to locate the assembly (See Fig. 31). NOTE: Dedicated low NO× models MUST be installed in California Air Quality Management Districts where a Low NO× rule exists. These models meet the California maximum oxides of nitrogen (NO×) emissions requirements of 40 nanograms/joule or less as shipped from the
factory. NOTE: Low NO× requirements apply only to natural gas installations.
A CAUTION: The venting system is designed to ensure proper venting. The flue hood assembly must be installed as
indicated in this section of the unit installation instructions.

install a gas supply line that runs to the heating section, Refer to Table 3 and the NFGC for gas pipe sizing. Do not use cast-iron pipe, It is recommended that a black iron pipe is used. Check the local utility for recommendations concerning existing lines. Size gas supply piping for 0.5
in. wg maximum pressure drop. Never use pipe smaller than the 1/2-in. FPT gas inlet on the unit gas valve. For natural gas applications, the gas pressure at unit gas connection must not be less than 4.0 in. wg or greater than 13 in. wg while the unit is
operating. For propane applications, the gas pressure must not be less than 7.0 in. wg or greater than 13 in. wg at the unit connection. An i/8-in. NPT plugged tapping, accessible for test gage connection, must be installed immediately upstream of the gas supply connection to the
gas valve. When installing the gas supply line, observe local codes pertaining to gas pipe installations. Refer to the NFGC ANSI Z223.1-1988 NFPA latest
edition (in Canada, CAN/CGA B149. I, (2)-M86). in the absence of local building codes, adhere to the following pertinent recommendations:
i. Avoid low spots in long runs of pipe. Grade all pipe I/4 in. in every 15 ft to prevent traps. Grade all horizontal runs downward to risers.
Use risers to connect to heating section and to meter.
2. Protect all segments of piping system against physical and thermal damage_ Support all piping with appropriate straps, hangers, etc. Use a minimum of one hanger every 6 ft. For pipe sizes larger than I/2 in., follow recommendations of national codes.
3. Apply joint compound (pipe dope) sparingly and only to male threads of joint when making pipe connections. Use only pipe dope that is resistant to action of liquefied petroleum gases as specified by local and/or national codes. Never use Teflon tupe.
4. Install sediment trap in riser leading to heating section (See Fig. 9). This drip leg functions as a trap for dirt and condensate.
5. Install an accessible, external, manual main shutoff valve in gas supply pipe within 6 ft of heating section.
6. Install ground-joint union close to heating section between unit manual shutoff and external manual main shut-off valve.
7. Pressure-test all gas piping in accordance with local and national plumbing and gas codes before connecting piping to unit.

B. SPECIAL PROCEDURES FOR 208-V OPERATION
z_x WARNING: Before making any wiring changes, make sure the gas supply is switched off first. Then switch off the power
supply to the unit and install lockout tag, Electrical shock can cause serious injury or death,
C. CONTROL VOLTAGE CONNECTIONS
Do not use any type of power-stealing thermostat. Unit control problems may result. Use no, 18 American Wire Gage (AWG) color-coded, insulated (35 C minimum) wires to make the control voltage connections between the
thermostat and the unit, if the thermostat is located more than 100 fi from the unit (as measured along the control voltage wires), use no. 16 AWG color-coded, insulated (35 C minimum) wires.
STANDARD CONNECTION
Remove knockout hole located in the flue panel adjacent to the control access panel (See Fig. 2 and 3). Remove the rubber grommet from the installer's packet (included with unit) and install grommet in the knockout opening. Provide a drip loop before running wire through panel.
Run the low-voltage leads from the thermostat, through the inlet hole, and into unit low-voltage splice box.
Locate five 18-gage wires leaving control box. These low-voltage connection leads can be identified by the colors red, green, yellow, brown, and white (See Fig. 11). Ensure the leads are long enough to be muted into the low-voltage splice box (located below right side of control box). Route leads through hole in bottom of control box and make low-voltage connections (See Fig. 11). Secure all cut wires, so that they do not interfere with operation of unit.
D. HEAT ANTICIPATOR SETTING
The room themmstat heat anticipator must be properly adjusted to ensure proper heating performance. Set the heat anticipator, using an ammeter between the W and R terminals to determine the exact required setting.
NOTE: For thermostat selection purposes, use 0.18 amp for the approximate required setting. Failure to make a proper heat anticipator adjustment will result in improper operation, discomfort to the occupants of the conditioned space, and inefficient energy utilization; however, the required
setting may be changed slightly to provide a greater degree of comfort for a particular installation.
E. TRANSFORMER PROTECTION
The trans[brmer is of the energy-limiting type. It is set to withstand a 30-sec. overload or shorted secondary condition.

B. CHECK GAS INPUT
Check gas input said tnanifbld pressure afier unit start-up (See Table 6). If adjustment is required proceed as fbllows:
The rated gas inputs shown in Table 6 are for altitudes from sea level to 2000 fl above sea level, These inputs are based on natural gas with
a heating value of 1050 B_'fL s at 0.65 specific gravib,, or propane gas with a heating value of 2500 Bta/ff s at 1,5 _cclfic gravity.
For elevations above 2000 fl, reduce input 4 pameat for each 1000 fL above sea level,
When the gas supply being used has a dlffereat heating value or specific gravity, refer m national and local codes, or contact your distributor to d_tenulne the reqtm_zd orifice size,
z_ CAUTION: These units are designed to consume the rated gas inputs using the fixed orifices at specified manifold
pressures as shown in Table 6, DO NOT REDRILL THE ORIFICES UNDER ANY CIRCUMSTANCES.
C. ADJUST GAS INPUT
The gas input to the unit is determined by measuring the gas flow ut the meter or by measuring the manifold pressure, Measuring the gas flow at the meter is recommended for natural gas units, The manifold pressure must be measured to determine the input of propane gas units,
MEASURE GAS FLOW (NATURAL GAS UNITS}
Minor adjustment to the gas flow can be made by changing the mmfifold pressure. The manifold pressure must be maintained between 3,4 and 3,6 in, wg, If lurger adjustments oa'ere.tired, change main burner orifices fbllowlng the recommendations of national and local codes,
NOTE: All other applimlecs that use the same meter must be _m'ned off whoa gas flow is measured at the meter.
Proceed as follows:
1, Turn off gas supply to tmlt,
2, Remove pipe plug on manifold (See Fig, 13) and connect mmlomcter. Turn on gas supply to unit,
3, Record number of seconds for gas meter test dial to make one revolution.
4, Divide number of seconds in Sto_ 3 into 3600 (number of seconds in one hour).
5, Multiply result of Ste9 4 1_, the number ofcu fl shown for one revolution of test dial to obtain en fi of gas flow per hour, 6, Multiply result of Nto_ 5 by Btu heudng value of gas to obtain total measured input in Btuh. Compare thls value _%4thhealing input shown
in Table 6 (Consult the local gas suppller if the healing value of gas is not known),
EXAMPLE: Assume that the size of test dial is 1 cufL one revolution takas 32 see,, and the healing value of the gas is 1050 Bta/ft s, Proceed as follows:
1, 32 sac, to complete one revolution,
2, 3600 + 32 = 112,5,
3, 112.5xl 112.Sf13ofgasflow/hr.
4, 112.5 x 1050 = 118,125 B_h input,
If the desired gas input is 115,000 Bmh, only a minor change in the mo:nlfold pressure is required, Ob_rve manifold pressure said proceed as follows to adjust gas input:

F, HEATING SEQUENCE OF OPERATION
(Sec Fig. 15-17 s:nd tm_t ,_g label), On a call for heuting, tt,_'minal "W" of the thermostat is energized, starting the indueed-draft motor, When the h011.-offect sensor on the
induced-draft motor _nsas that it has reached the reqtfired _ecd, the burner sequence begins, This rime'don is performed by the integrated gas control (IGC). The evaporator-fan motor is cnargJzed 45 scc, after flame is established. When the thermostat is satisfied s:nd "W" is deanergJzed,
the burnars stop firing and the evaporator-fan motor shuts off after a 45-see. tlmc-off delay. An LED (light-emi_g diode) indicator is provided on the control bom'd,to monitor operation. The control board is locuted by removing the burner
aecass panel. Dung normal operation, the LED is contlnueusly on (See Table 8 for error codes).
G, LIMIT SWITCHES
Normally closed, limit sv¢iteh (LS) completes the control clrcult through the thermostat R clrcult. Should the leaving-sir temparature rise above the maximum allowable temparature, the lhnit switeh opens s:nd the R control clrmtit "breaks." Any interruption in the R control elrertit instantly
closes the gas valve s:nd stops gas flow to the burners s:nd pilot. The blower motor continues to nm tmtll LS resets, When the _ tompem_ at the limit swlteh drops to the low- tomperature setting of the limit sv¢iteh, the switeh closes s:nd completes the R cantml
cirealt. The electric-spark ignltion _stom cyclas and the tmlt retm'ns to normal heutSng operation.
