3. These instructions contai n importa nt inform ation for
the proper maintenance and repair of this equipment.
Retain these instructions for futu re use.
Installation and servicing of air-conditioning equipment can
be hazardous due to system pressure and electrical components. Only trained and qualified service personnel should
install, repair, or servic e air-conditioning equipment.
Untrained personnel can perform basic maintenance functions of cleaning coils and filters and replacing filters. All
other operations sh o uld be perfor me d by trai ne d se rvi ce personnel. When working on air-conditioning equipment,
observe precautions in the literature, tags and labels
attached to the unit, and other safety precautions that apply.
Follow all safety codes. Wear safety glasses and work gloves.
Use quenching cloth for unbrazing operations. Have fire
extinguishers available for all brazing opera tions.
WARNING: Disconnect gas piping from unit when
leak testing at pressure greater than 1/2 psig. Pressures greater tha n
resulting in hazardous condition. If gas valve is subjected to pressure greater than
replaced before use. When pressure testing fieldsupplied gas piping at pressures of
unit connected to such piping must be isolated by manually closing the gas valve.
WARNING: Before performing service or maintenance operations on unit, turn off main power switch
to unit and install a lockout tag. Electrical shock could
cause personal injury.
CAUTION: Ensure voltage listed on unit data plate
agrees with electrical supply p r ov ided fo r t he unit .
Unit is ship ped in t he ve rti cal d uc t con figu rat ion . To convert t o
horizontal configuration, remove screws from side duct opening covers and remove covers. Using the same screws, install
covers on vertical duct openings with the insulation-side down.
Seals around duct openings must be tight. See Fig. 2.
Confirm before installation of unit that voltage, amperage
and circuit protection requirements listed on unit data plate
agree with power supply provided.
I. STEP 1 — PROVIDE UNIT SUPPORT
A. Roof Curb
Assemble and install accessory roof curb in accordance with
instructions shipped with curb. See Fig. 3. Install insulation,
cant strips, roofing felt, and counter flashing as shown. Duct-
work must be attached to curb, not to the unit. The accessory
thru-the-bottom power and gas connection package must be
installed before the unit is set on the roof curb. If field-
installed (thru-the-roof curb) gas connections are desired, use
factory-supplied
to mount the thru-the-roof curb connection to the roof curb.
Gas connections and power connections to the unit must be
field installed after the unit is installed on the roo f curb.
If electric and control wiring is to be routed through the
basepan, attach the accessory thru-the-bottom service connections to the basepan in accordance with the accessory
installation instructions.
IMPORTANT: The gasketing of the unit to the roof curb is
critical for a watertight seal. Install gasket supplied with the
roof curb as shown in Fig. 3. Improperly applied gasket can
result in air leaks and poor unit performance.
Curb should be level. Unit leveling tolerances are shown in
Fig. 4. This is necessary for unit drain to function properly.
Refer to Accessory Roof Curb Installation Instructions for
additional information as required.

NOTE: Horizontal units may be installed on a roof curb if
required.
C. Alternate Unit Support
A non-combustible sleepe r rail can be used in the unit curb
support area. If sleeper rails cannot be used, support the
long sides of the unit with a minimum of 3 equally spaced
4-in. x 4-in. pads on each side.
II. STEP 2 — FIELD FABRICATE DUCTWORK
Secure all ducts to roof curb and building s tructure on verti cal ducted units. Do not connect ductwork to unit. For h or izontal applications, fiel d-supplie d flanges sh ould b e attach ed
to horizontal duct openings and all ductwork should be
secured to the flanges. Insulate and weatherproof all external ductwork, joints , and roo f openings with counter flashing
and mastic in accordance with applicable codes.
Ducts passing through a n unc ondit i one d spa ce must be insulated and covered with a vapor barrier.
If a plenum return is used on a vertical unit, the return
should be ducted through the roof deck to comply with applicable fire codes.
A minimum clearance is not required around ductwork. Cabinet return air static pressure (a negative condition) should
not exceed 0.35 in. wg with economizer or 0.45 in. wg without economizer.
These units are designed for a minimum continuous heating
return-air temperature of 50 F (dry bulb), or an intermittent
operation down to 45 F (dry bulb), such as when used with a
night set-back thermostat.
To operate at lower return-air temperatures, a field-supplied
outdoor air temperature control must be used to initiate both
stages of heat when the temperature is below 45 F. Indoor
comfort may be compromised when these lower air temperatures are used with insufficient heating temperature rise.
III. STEP 3 — INSTALL EXTERNAL TRAP FOR CONDENSATE DRAIN
The unit’s
3
/4-in. condensate drain connections are located
on the bottom and side of the unit. Unit discharge connections do not determine the use of drain connections; either
drain connection can be used with vertical or horizontal
applications.
When using the standard side drain connection, make sure
the plug (Red) in the alternate bottom connection is tight
before installing the unit.
To use the bottom drain connection for a roof curb installation,
relocate the factory-i nstalle d plug (Re d) from t he bott om connection to the side connection. The center dr ain plug l ooks like
a star connection, however it can be removed with a
1
/2-in.
socket drive. See Fig. 5A. The piping for the condensate drain
and external trap can be completed after the unit is in place.
All units must have an external trap for condensate drainage.
Install a trap at least 4-in. deep and protect against freeze-up. If
drain line is installed downstream from the external trap, pitch
the line away fr om the unit at 1 in. per 10 ft of r un. Do not use a
pipe size smaller than the unit connection (
3
/4 in.). See Fig. 5B.
IV. STEP 4 — RIG AND PLACE UNIT
Inspect unit for transportation damage. File any claim with
transportation agency. Keep unit upright and do not drop.
Spreader bars are not required if top crating is left on unit.
Rollers may be used to move unit across a roof. Level by
using unit frame as a ref erence. See Table 1 and Fi g. 6 for
additional information.
Lifting holes are provided in base rails as shown in Fig. 1A
and 1B. Refer to rigging instructions on unit.
CAUTION: All panels must be in place when rigging.
Unit is not designed for handling by a fork truck. Damage
to unit may result.

curb:
/4-in. clearance between roof curb and base rails on
each side and duct end of unit; 1/4-in. clearance between roof
curb and condenser coil end of unit . (See Fig. 3, section C-C.)
Do not install unit in an indoor location. Do not locate unit
air inlets near exhaust vents or other sources of contaminated air.
Be sure that unit is installed such that snow will not block
the combustion intake or flue outlet.
Unit may be installed directly on wood flooring or on Class
A, B, or C roof-covering material when roof curb is used.
Although unit is weatherproof, guard against water from
higher level runoff and overhangs.
Flue vent discharge must have a minimum horizontal clearance of 4 ft from electric and gas meters, gas regulators, and
gas relief equipment.
Minimum distance between unit and other electrically live
parts is 48 inches.
Flue gas can deteriorate building materials . Orie nt unit suc h
that flue gas will not affect building materials.
Adequate combustion-air space must be provided for
proper operation of this equipment. Be sure that installation
complies with all local codes and Section 5.3, Air for Combustion and Ventilation, NFGC (National Fuel Gas Code), and
ANSI (American National Standards Institute) Z223.1, and
NFPA (National Fire Protectio n As so ci atio n) 5 4 TI A -54 -84- 1.
In Canada, installation must be in accordance with the
CAN1-B149 installation codes for gas burning appliances.
After unit is in position, remove rigging skids and shipping
materials.
V. STEP 5 — INSTALL FLUE HOOD
Flue hood is shipped screwed to the basepan beside the
burner compartment access panel. Remove from shipping
location and using screws provided, install flue hood and
screen in location shown in Fig. 7.
VI. STEP 6 — INSTALL GAS PIPING
Unit is equipped for use wi th type of gas shown on nameplate. Refer to local building codes, or in the absence of local
codes, to ANSI Z223.1 entitled National Fuel Gas Code. In
Canada, installation must be in accordance with the
CAN1.B149.1 and CAN1.B149.2 installation codes for gas
burning appliances.
For natural gas applications, gas pressure at unit gas connection must not be less than 4 in. wg or greater than
13.0 in. wg while unit is oper atin g. On 580F04 8,0 60,072 high
heat units, the gas pressure at unit gas connection must not
be less than 5 in. wg or greater than 13 in. wg while the unit
is operating. For propane applications, the gas pressure
must not be less than 5 in. wg or greater than 13 in. wg at
the unit connection.
Size gas supply piping for 0.5 in. wg maximum pressure
drop. Do not use supply pipe smaller than unit gas connection. Support gas pipi ng as shown in the ta ble in Fig. 8. For
example, a
3
/4-in. gas pipe must have one field-fabricated
support beam every 8 ft. Therefore, an 18-ft long gas pipe
would have a minimum of 2 support beams, a 48-ft long pipe
would have a minimum of 6 support beams.
See Fig. 8 for typical pipe guide and locations of external
manual main shutoff valve.
CAUTION: When connecting the gas line to the
unit gas valve, the installer MUST use a backup
wrench to prevent valve damage.

A. Field Power Supply
All units except 208/230-v units are factory wired for the
voltage shown on the na meplate. If the 208/230-v u nit is to
be connected to a 208-v power supply, the transformer must
be rewired by m oving the blac k wire with th e
1
/4-in. female
space connector from the 230-volt connection and moving to
the 208-volt
1
/4-in. male terminal on the primary side of the
transformer.
Refer to unit label diagram for additional information.
Pigtails are provided for fie ld wire connectio ns. Use factorysupplied splices or UL (Underwriters’ Laboratories)
approved copper/aluminum connector.
When installing units, provide a disconnect per the NEC.
All field wiring must comply with NEC and local require-
ments.
Install field wiring as foll ows:
1. Install conduit through side panel openings. Install
conduit between disconnect and control box.
2. Install power lines to terminal connections as shown
in Fig. 9.
Voltage to compressor terminals during operation must be
within voltage range indicated on unit nameplate (see
Tables 2A and 2B). On 3-phase units, voltages between
phases must be balanced within 2% and the current within
10%. Use the formula shown in the legend for Tables 2A and
2B, Note 2 to determine the percent of voltage imbalance.
Operation on impr op er lin e volta ge or excess ive phase imbalance constitutes abuse and may cause damage to electrical
components. Such operation would invalidate any applicable
Bryant warranty.
B. Field Control Wiring
Install a Bryant-approved accessory thermostat assembly
according to installation instructions included with the
accessory. Locate thermostat assembly on a solid wall in the
conditioned space to sense average temperature in accordance with thermostat installation instructions. Connect
thermostat wires to terminal board.

Maximum deviation is 7 v.
Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric
utility company immediately.
3. For units with power exhaust: If a single power source is to be used, size wire to include
power exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is powered
through the unit (must be in accordance with NEC and/or local codes). Determine the new
MCA including the power exhaust using the following formula:
MCA New = MCA unit only + MCA of Power Exhaust
For example, using a 580F060 unit with MCA = 28.9 and MOCP = 35, with
CRPWREXH030A01 power exhaust.
MCA New = 28.9 amps + 1.6 amps = 30.5 amps
If the new MCA does not exceed the published MOCP, then MOCP would not change. The
MOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is
acceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the next
larger size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.

NOTES:
1. In compliance with NEC requirements for multimotor and combination load equipment (refer
to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or
HACR breaker. Canadian units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply voltage is greater than 2%.
the following formula to determine the percent of voltage imbalance.
% Voltage Imbalance
= 100 x
Example: Supply voltage is 460-3-60.
Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v
(BC) 464 – 457 = 7 v
(AC) 457 – 455 = 2 v

Maximum deviation is 7 v.
Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric
utility company immediately.
3. For units with power exhaust: If a single power source is to be used, size wire to include
power exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is powered
through the unit (must be in accordance with NEC and/or local codes). Determine the new
MCA including the power exhaust using the following formula:
MCA New = MCA unit only + MCA of Power Exhaust
For example, using a 580F060 unit with MCA = 28.9 and MOCP = 35, with
CRPWREXH030A01 power exhaust.
MCA New = 28.9 amps + 1.6 amps = 30.5 amps
If the new MCA does not exceed the published MOCP, then MOCP would not change. The
MOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is
acceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the next
larger size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.
The outdoor-air hood and screen are attached to the basepan
at the bottom of the unit for shipping.
Assembly:
1. Determine quantity of ventilation required for building. Record amount for use in Step 8.
2. Remove and save outdoor air opening panel and
screws. See Fig. 12.
3. Separate hood and screen from basepan by removing
