IV. PROVIDE CLEARANCES

The required minimum operating and service clearances are shown
in Fig. 6 and 7. Adequate combustion, ventilation, and condenser
air must be provided, in accordance with section 5.3, Air for
Combustion and Ventilation, of the National Fuel Gas Code ANSI
(American National Standards Institute) Z223.1 (in Canada, sec­tions 7.2, 7.3 or 7.4 or Can/CGA (Canadian Gas Association)
B149 Installation Codes), or applicable provisions of local build­ing code.

CAUTION: Do not restrict condenser airflow. An air

restriction at either the outdoor-air inlet or the fan

discharge can be detrimental to compressor life.

The condenser pulls air through the condenser coil and discharges
it through the top cover. Be sure that the fan discharge does not
recirculate to the condenser coil. Do not locate the unit in either a
corner or under an overhead obstruction. The minimum clearance
under a partial overhang (such as a normal house overhang) is
48-in. above the unit top. The maximum horizontal extension of a
partial overhang must not exceed 48 inches.

Do not place the unit where water, ice, or snow from an overhang
or roof will damage or flood the unit. Do not install the unit on
carpeting, tile, or other combustible materials. The unit may be
installed on wood flooring or on Class A, B, or C roof covering
materials.

V. RIG AND PLACE UNIT

Rigging and handling of this equipment can be hazardous for many
reasons due to the installation location (roofs, elevated structures,
etc.).

Only trained, qualified crane operators and ground support staff
should handle and install this equipment.

When working with this equipment, observe precautions in the
literature, on tags, stickers and labels attached to the equipment,
and any other safety precautions that might apply.

Training for operations of the lifting equipment should include, but
NOT be limited to the following:

1. Application of the lifter to the load and adjustment of the
lifts, if any, that adapts it to various sizes or kinds of loads.

2. Instruction in any special operation or precaution.

3. Condition of the load itself, required for operation of the
lifting kit, such as balance, temperature, etc.

Follow all applicable safety codes. Wear safety shoes and work
gloves.

WARNING:

Never exceed 200 lbs. per bracket lifting force.
Accessory lifting kit is only to be used with Small
Packaged units which have a composite base pan with
molded hand holds.
Never stand beneath rigged units or lift over people.
Lifting point should be directly over the center of gravity
for the unit.
A dropped unit could cause serious injury or death.

INSPECTION — Prior to initial use, and at monthly intervals, all
rigging brackets and straps should be visually inspected for any
damage, evidence of wear, structural deformation, or cracks.
Particular attention should be paid to excessive wear at hoist
hooking points and load support areas. Brackets or straps showing
any kind of wear in these areas must not be used and should be
discarded.

INSTALLATION:

1. Position the lifting bracket assembly around the base of the
unit. Leave the top shipping skid on the unit to act as a
spreader bar. Be sure the strap does not twist.

2. Place each of the four (4) metal lifting brackets into the
handholds in the composite pan.

3. Tighten the ratchet strap until tight. Lifting brackets should
be secure in the handholds.

4. Attach the clevis or hook of sufficient strength to hole in the
lifting bracket as shown in Fig. 8.

5. Attach safety straps directly to the field supplied rigging
straps or clevis clip. Do not attach the safety straps to the
lifting brackets.

6. Use the top of the unit as a spreader bar to prevent the
rigging straps from damaging the unit. If the wood top is not
available, use a spreader bar of sufficient length to not
damage the unit.

VI. CONNECT CONDENSATE DRAIN

NOTE: When installing condensate drain connection be sure to

comply with local codes and restrictions.

The 583B units dispose of condensate water through a 3/4 in. NPT
fitting which exits through the compressor access panel. See Fig.
6 and 7 for location.

Condensate water can be drained directly onto the roof in rooftop
installations (where permitted) or onto a gravel apron in ground­level 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. 9. Prime the trap with water. When using a gravel apron, make
sure it slopes away from the unit.

codes and other applicable local codes.

2. Remove flue hood from shipping location (inside the
blower compartment). Place vent cap assembly over flue
panel. Orient screw holes in vent cap with holes in the flue
panel.

—7—

3. Secure flue hood to flue panel by inserting a single screw on
the right side and the left side of the hood.

VIII. INSTALL GAS PIPING

The gas supply pipe enters the unit through the access hole
provided. The gas connection to the unit is made to the 1/2-in. FPT
gas inlet on the manual shutoff or gas valve.

Install a gas supply line that runs to the heating section. Refer to
Table 4 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.

A 1/8-in. NPT plugged tapping accessible for test gauge 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, NFPA
54 latest edition (in Canada, CAN/CGA B149.1, B149.2 latest
edition). In the absence of local building codes, adhere to the
following pertinent recommendations:

1. Avoid low spots in long runs of pipe. Grade all pipe 1/4 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 1/2 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 tape.

4. Install sediment trap in riser leading to heating section per
Fig. 10. 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 shutoff
valve.

7. Pressure-test all gas piping in accordance with local and
national plumbing and gas codes before connection of
piping to unit.

NOTE: The supply piping must be disconnected from the gas
valve during the testing of the piping systems when test pressure is
in excess of 0.5 psig (13.8 WC). If the test pressure is equal to or
less than 0.5 psig, the unit heating section must be isolated from
the gas piping system by closing the external main manual shutoff
valve and slightly opening the ground-joint union.

CAUTION: Unstable operation may occur when the gas
valve and manifold assembly are forced out of position
while connecting improperly routed rigid gas piping to
the gas valve. Use a backup wrench when making
connection to avoid strain on, or distortion of, the gas
control piping.

CAUTION: If a flexible conductor is required or al­lowed by the authority having jurisdiction, black iron
pipe shall be installed at the gas valve and shall extend a
minimum of 2 in. outside the unit casing.

WARNING: Never use a match or other open flame
when checking for gas leaks. Never purge gas line into
combustion chamber. Failure to follow this warning
could result in an explosion causing serious injury or
death

8. Check for gas leaks at the field-installed and factory­installed gas lines after all piping connections have been
completed. Use soap and water solution (or method speci­fied by local codes and/or regulations).

IX. INSTALL DUCT CONNECTIONS

The unit has duct flanges on the supply- and return-air openings on
the side and bottom of the unit. For downshot applications the
ductwork can be connected to the roof curb. See Fig. 6 and 7 for
connection sizes and locations.

CONFIGURING UNITS FOR DOWNFLOW (VERTICAL) DIS­CHARGE

WARNING: Before performing service or maintenance
operations on the system, turn off main power to unit.
Electrical shock could cause serious injury or death.

1. Open all electrical disconnects before starting any service
work.

2. Remove return duct cover located on duct panel by breaking
connecting tabs with screwdriver and a hammer (Fig. 11).

3. To remove supply duct cover, break front and right side
connecting tabs with a screwdriver and a hammer. Push
louver down to break rear and left side tabs (Fig. 12).

4. If unit ductwork is to be attached to vertical opening flanges
on the unit basepan (jackstand applications only), do so at
this time. Collect ALL screws that were removed. Do not
leave screws on rooftop as permanent damage to the roof
may occur.

5. It is recommended that the basepan insulation around the
perimeter of the vertical return-air opening be secured to the
basepan with aluminum tape. Applicable local codes may
require aluminum tape to prevent exposed fiberglass.

6. Cover both horizontal duct openings with the duct covers
from the accessory duct cover kit. Ensure opening is air-and
watertight.

7. After completing unit conversion, perform all safety checks
and power up unit.

NOTE: The design and installation of the duct system must be in
accordance with the standards of the NFPA for installation of
nonresidence-type air conditioning and ventilating systems, NFPA
90A or residence-type, NFPA 90B; and/or local codes and

A. Adhere to the following criteria when selecting,
sizing, and installing the duct system:

1. Units are shipped for side shot installation.

2. Select and size ductwork, supply-air registers, and return-air
grilles according to American Society of Heating, Refrig­eration and Air Conditioning Engineers (ASHRAE) recom­mendations.

3. Use flexible transition between rigid ductwork and unit to
prevent transmission of vibration. The transition may be
screwed or bolted to duct flanges. Use suitable gaskets to
ensure weather tight and airtight seal.

4. All units must have field-supplied filters or accessory filter
rack installed in the return-air side of the unit. Recom­mended sizes for filters are shown in Tables 2 and 3.

5. Size all ductwork for maximum required airflow (either
heating or cooling) for unit being installed. Avoid abrupt
duct size increases or decreases or performance may be
affected.

6. Adequately insulate and weatherproof all ductwork located
outdoors. Insulate ducts passing through unconditioned
space, and use vapor barrier in accordance with latest issue

of Sheet Metal and Air Conditioning Contractors National
Association (SMACNA) and Air Conditioning Contractors
of America (ACCA) minimum installation standards for
heating and air conditioning systems. Secure all ducts to
building structure.

7. Flash, weatherproof, and vibration-isolate all openings in
building structure in accordance with local codes and good
building practices.

X. INSTALL ELECTRICAL CONNECTIONS

WARNING: The unit cabinet must have an uninter-

rupted, unbroken electrical ground to minimize the pos­sibility of serious injury if an electrical fault should occur.
This ground may consist of an electrical wire connected
to the unit ground lug in the control compartment, or
conduit approved for electrical ground when installed in
accordance with NEC (National Electrical Code) ANSI/
NFPA 70 (latest edition) (in Canada, Canadian Electrical
Code CSA (Canadian Standards Association) C22.1) and
local electrical codes. Do not use gas piping as an
electrical ground. Failure to adhere to this warning could
result in serious injury or death.
