Installation of the gas piping must be accordance with
local building codes and with applicable national codes.
In U.S.A., refer to NFPA 54/ANSI Z223.1 National Fuel
Gas Code (NFGC). In Canada, installation must be
accordance with the CAN/CSA B149.1 and CAN/CSA
B149.2 installation codes for gas burning appliances.
This unit is factory equipped for use with Natural Gas fuel
at elevations up to 2000 ft (610 m) above sea level. Unit
may be field converted for operation at elevations above
2000 ft (610 m) and/or for use with liquefied petroleum
fuel. See accessory kit installation instructions regarding
these accessories.
NOTE: Furance gas input rate on rating plate is for
installation up to 2000 ft (610 m) above sea level. In
U.S.A. the input rating for altitudes above 2000 ft (610 m)
must be derated by 4% for each 1000 ft (305 m) above sea
level. In Canada the input rating must be derated by 10%
for altitudes of 2000 ft (610 m) to 4500 ft (1372 m) above
sea level.
For natural gas applications, gas pressure at unit gas
connection must not be less than 5 in. wg (1246 Pa) or
greater than 13 in. wg (3240 Pa) while the unit is
operating. For liquified petroleum applications, the gas
pressure must not be less than 11 in. wg (2740 Pa) or
greater than 13 in. wg (3240 Pa) at the unit connection.
The gas supply pipe enters the unit adjacent to the burner
access panel on the front side of the unit, through the
grommeted hole. The gas connection to the unit is made

EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in damage
to equipment.
When connecting the gas line to the unit gas valve,
the installer MUST use a backup wrench to prevent
damage to the valve.
CAUTION
!
Install a gas supply line that runs to the unit heating
section. Refer to the NFPA 54/NFGC or equivalent code
for gas pipe sizing data. Do not use a pipe smaller than the
size specified. Size the gas supply line to allow for a
maximum pressure drop of 0.5--in wg (124 Pa) between
gas regulator source and unit gas valve connection when
unit is operating at high--fire flow rate.
The gas supply line can approach the unit in two ways:
horizontally from outside the unit (across the roof), or
through unit basepan.
Factory--Option Thru--Base Connections —
Electrical Connections: Knockouts are located in the
control box area. Remove the appropriate size knockout
for high voltage connection. Use the field supplied
connector depending on wiring or conduit being utilized.
Remove the 7/8--in (22mm) knockout and appropriate
connector for low voltage wiring. If non--powered
convenience outlet is being utilized remove the 7/8-- i n
(22mm) knockout and utilize appropriate connector for
115 volt line. See “Step 12 — Making Electrical
Connections” for details.
Gas Connections: Remove the knockout in the base pan
and route 3/4--in. gas line up through the opening. Install
an elbow and route gas line through opening in panel after
first removing plastic bushing. Install a gas shut off
followed by a drip leg and ground--joint union. Route gas
line into gas section through the grommet (Part #:
KA56SL112) at the gas inlet and into the gas valve. See
Fig. 16. If a regulator is installed, it must be located 4 feet
(1.22 meters) from the flue outlet.
Some municipal codes require that the manual shutoff
valve be located upstream of the sediment trap. See
Fig. 15 for typical piping arrangements for gas piping that
has been routed through the sidewall of the base pan.

When installing the gas supply line, observe local codes
pertaining to gas pipe installations. Refer to the NFPA
54/ANSI Z223.1 NFGC latest edition (in Canada, CAN/CSA
B149.1). In the absence of local building codes, adhere to
the following pertinent recommendations:
580J***D

15
1. Avoid low spots in long runs of pipe. Grade all pipe
1/4--in. in every 15 ft (7 mm in every 5 m) 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 appro-
priate straps, hangers, etc. Use a minimum of one
hanger every 6 ft (1.8 m). 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 connec-
tions. Use only pipe dope that is resistant to action of
liquefied petroleum gases as specified by local and/or
national codes. If using PTFE (Teflon) tape, ensure
the material is Double Density type and is labeled for
use on gas lines. Apply tape per manufacturer’s in-
structions.
4. Pressure--test all gas piping in accordance with local
and national plumbing and gas codes before connect-
ing piping to unit.
NOTE: Pressure test the gas supply system after the gas
supply piping is connected to the gas valve. 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 (3450 Pa). Pressure test the gas supply
piping system at pressures equal to or less than 0.5 psig
(3450 Pa). 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.
Check for gas leaks at the field--installed and
factory--installed gas lines after all piping connections
have been completed. Use soap--and--water solution (or
method specified by local codes and/or regulations).
FIRE OR EXPLOSION HAZARD
Failure to follow this warning could result in personal
injury, death and/or property damage.
SConnect gas pipe to unit using a backup wrench to
avoid damaging gas controls.
SNever purge a gas line into a combustion chamber.
SNever test for gas leaks with an open flame. Use a
commercially available soap solution made
specifically for the detection of leaks to check all
connections.
SUse proper length of pipe to avoid stress on gas
control manifold.
!WARNING
NOTE: If orifice hole appears damaged or it is suspected
to have been redrilled, check orifice hole with a numbered
drill bit of correct size. Never redrill an orifice. A
burr--free and squarely aligned orifice hole is essential for
proper flame characteristics.

Field Power Supply —
If equipped with optional Powered Convenience Outlet:
The power source leads to the convenience outlet’s
transformer primary are not factory connected. Installer
must connect these leads according to required operation
of the convenience outlet. If an always--energized
convenience outlet operation is desired, connect the
source leads to the line side of the unit--mounted
disconnect. (Check with local codes to ensure this method
is acceptable in your area.) On a unit without a
unit--mounted disconnect, connect the source leads to the
terminal block with unit field power leads.
Field power wires are connected to the unit at line--side
pressure lugs on the terminal block (see wiring diagram
label for control box component arrangement) or at
factory--installed option non--fused disconnect switch. Use
copper conductors only.
NOTE: Make field power connections directly to line
connection pressure lugs only.
All units except 208/230-v units are factory wired for the
voltage shown on the nameplate. If the 208/230-v unit is
to be connected to a 208-v power supply, the control
transformer must be rewired by moving the black wire
with the 1/4-in. female spade connector from the 230--v
connection and moving it to the 208-v 1/4-in. male
terminal on the primary side of the transformer. Refer to
unit label diagram for additional information.

Installing Weatherproof Cover –
A weatherproof while-in-use cover for the
factory-installed convenience outlets is now required by
UL standards. This cover cannot be factory-mounted due
its depth; it must be installed at unit installation. For
shipment, the convenience outlet is covered with a blank
cover plate.
The weatherproof cover kit is shipped in the unit’s control
box. The kit includes the hinged cover, a backing plate
and gasket.
DISCONNECT ALL POWER TO UNIT AND
CONVENIENCE OUTLET.
Remove the blank cover plate at the convenience outlet;
discard the blank cover.
Loosen the two screws at the GFCI duplex outlet, until
approximately 1/2-in (13 mm) under screw heads are
exposed. Press the gasket over the screw heads. Slip the
backing plate over the screw heads at the keyhole slots
and align with the gasket; tighten the two screws until
snug (do not over-tighten).
Mount the weatherproof cover to the backing plate as
shown in Fig. 23. Remove two slot fillers in the bottom of
the cover to permit service tool cords to exit the cover.
Check for full closing and latching.

Non--powered type: This type requires the field
installation of a general--purpose 125--volt 15--A circuit
powered from a source elsewhere in the building. Observe
national and local codes when selecting wire size, fuse or
breaker requirements and disconnect switch size and
location. Route 125--v power supply conductors into the
bottom of the utility box containing the duplex receptacle.
Unit--powered type: A unit--mounted transformer is
factory--installed to stepdown the main power supply
voltage to the unit to 115--v at the duplex receptacle. This
option also includes a manual switch with fuse, located in
a control box and mounted on a bracket behind the
convenience outlet; access is through the unit’s control
box access panel. See Fig. 22.
The primary leads to the convenience outlet transformer
are not factory--connected. If local codes permit, the
transformer primary leads can be connected at the
line--side terminals on the unit--mounted non--fused
disconnect or HACR breaker switch; this will provide
service power to the unit when the unit disconnect switch
or HACR switch is open. See Fig. 24.

Duty Cycle: the unit--powered convenience outlet has a
duty cycle limitation. The transformer is intended to
provide power on an intermittent basis for service tools,
lamps, etc; it is not intended to provide 15--amps loading
for continuous duty loads (such as electric heaters for
overnight use). Observe a 50% limit on circuit loading
above 8--amps (i.e., limit loads exceeding 8--amps to 30
minutes of operation every hour).
Test the GFCI receptacle by pressing the TEST button on
the face of the receptacle to trip and open the receptacle.
Check for proper grounding wires and power line phasing

if the GFCI receptacle does not trip as required. Press the
RESET button to clear the tripped condition.
Fuse on power type: The factory fuse is a Bussman
FNQ--7 dual element time delay fuse.
Using unit--mounted convenience outlets: Units with
unit--mounded convenience outlet circuits will often
require that two disconnects be opened to de--energize all
power to the unit. Treat all units as electrically energized
until the convenience outlet power is also checked and
de--energization is confirmed. Observe National Electrical
Code Article 210, Branch Circuits, for use of convenience
outlets.
Factory--Option Thru--Base Connections —
All units are equipped with the ability to bring utilities
through the base.
Gas is brought up through an embossed area located in the
gas section behind the gas entrance post. Access is gained
through the gas access panel. A knock out must be
removed to accomplish this.
The electrical entrance is located in the control box area
can can be accessed through the control box access panel.
An embossed area is provided with three knock outs. High
voltage is brought through the multi knock out by
removing the appropriate size for the size of the fitting
required. A 7/8--in. knock out is provided for low voltage.
An additional 7/8--in. knock out is provided for a 115 volt
line which is used when the unit is equipped with the
non--powered convenience outlet option.
All required fittings are field supplied. Install fittings
when access to both top and bottom of the base pan is
available. See electrical and gas connections for routing
and connection information.
Units without Thru--Base Connections —
1. Install conduit, liquid tight, between disconnect and
control box.
2. Pull correctly rated high voltage wires through the
conduit.
3. Install power lines to terminal connections as shown
in Fig. 21.
All Units —
Voltage to compressor terminals during operation must be
within voltage range indicated on unit nameplate. On
3--phase units, voltages between phases must be balanced
within 2% and the current within 10%. Use the following
formula to determine the percent of voltage imbalance.
% Voltage Imbalance = 100 x max voltage deviation from average voltage
average voltage
C09103
Operation on improper line voltage or excessive phase
imbalance constitutes abuse and may cause damage to
electrical components. Such operation would invalidate
any applicable Bryant warranty.
Field Control Wiring —
The 580J***D unit requires an external temperature
control device. This device can be a thermostat emulation
device provided as part of a third--party Building
Management System.
Thermostat —
Install a Bryant--approved accessory 2--stage thermostat
according to installation instructions included with the
accessory. Locate the thermostat accessory on a solid wall
in the conditioned space to sense average temperature in
accordance with the thermostat installation instructions.
If the thermostat contains a logic circuit requiring 24--v
power, use a thermostat cable or equivalent single leads of
different colors with minimum of seven leads. If the
thermostat does not require a 24--v source (no “C”
connection required), use a thermostat cable or equivalent
with minimum of six leads. Check the thermostat
installation instructions for additional features which
might require additional conductors in the cable.
For wire runs up to 50 ft. (15 m), use no. 18 AWG
(American Wire Gage) insulated wire (35_C minimum).
For50to75ft.(15to23m),useno.16AWGinsulated
wire (35_C minimum). For over 75 ft. (23 m), use no. 14
AWG insulated wire (35_C minimum). All wire sizes
larger than no. 18 AWG cannot be directly connected to
the thermostat and will require a junction box and splice
at the thermostat.
Unit without thru--base connection kit —
Correctly rated low voltage wire can be routed through the
rubber grommet located on the corner post adjacent to the
control box access panel. Route wire through the grommet
and then route the wire behind the corner post utilizing the
factory provided wire ties secured to the control box. This
will insure separation of the field low voltage wire and the
high voltage circuit. Route the low voltage wire to the
central terminal board. See Fig. 25.
