INSTALLATION
Job-Site Survey —
installation.
1. Consult local building codes and the NEC (National
Electrical Code) ANSI/NFPA 70 for special installation requirements.
2. Determine unit location (from project plans) or select unit
location.
3. Check for possible overhead obstructions which may interfere with unit lifting or rigging.
Step 1 — Plan for Unit Location — Select a location
for the unit and its support system (curb or other) that provides
for the minimum clearances required for safety. This includes
the clearance to combustible surfaces, unit performance and
service access below, around and above unit as specified in unit
drawings. See Fig. 2.
NOTE: Consider also the effect of adjacent units. Be sure
that unit is installed such that snow will not block the combustion intake or flue outlet.
Complete the following checks before
Unit may be installed directly on wood flooring or on Class
A, B, or C roof-covering material when roof curb is used.
Do not install unit in an indoor location. Do not locate air inlets near exhaust vents or other sources of contaminated air. For
proper unit operation, adequate combustion and ventilation air
must be provided in accordance with Section 5.3 (Air for Combustion and Ventilation) of the National Fuel Gas Code, ANSI
Z223.1 (American National Standards Institute) and NFPA
(National Fire Protection Association) 54 TIA-54-84-1. In
Canada, installation must be in accordance with the CAN1B149 installation codes for gas burning appliances.
Although unit is weatherproof, avoid locations that permit
water from higher level runoff and overhangs to fall onto the
unit.
Locate mechanical draft system flue assembly at least 4 ft
(1.2 m) from any opening through which combustion products
could enter the building, and at least 4 ft (1.2 m) from any adjacent building (or per local code). Locate the flue assembly at
least 10 ft (3.05 m) from an adjacent unit’s fresh air intake hood
if within 3 ft (0.91 m) of same elevation (or per local code).
When unit is located adjacent to public walkways, flue assembly must be at least 7 ft (2.1 m) above grade.
Select a unit mounting system that provides adequate height
to allow installation of condensate trap per requirements. Refer
to Step 11 — Install External Condensate Trap and Line – for
required trap dimensions.

tribution requirements. Unit operating weight is shown in
Table 2.
Step 2 — Plan for Sequence of Unit Installation —
The support method used for this unit will dictate different
sequences for the steps of unit installation. For example, on
curb-mounted units, some accessories must be installed on the
unit before the unit is placed on the curb. Review the following
for recommended sequences for installation steps.
CURB-MOUNTED INSTALLATION
1. Install curb
2. Install field-fabricated ductwork inside curb
3. Install accessory thru-base service connection package
(affects curb and unit) (refer to accessory installation instructions for details)
4. Prepare bottom condensate drain connection to suit
planned condensate line routing (refer to Step 11 for details)
5. Rig and place unit
6. Install outdoor air hood
7. Install flue hood
8. Install gas piping
9. Install condensate line trap and piping
10. Make electrical connections
11. Install other accessories
PAD-MOUNTED INSTALLATION
1. Prepare pad and unit supports
2. Check and tighten the bottom condensate drain connection plug
3. Rig and place unit
4. Convert unit to side duct connection arrangement
5. Install field-fabricated ductwork at unit duct openings
6. Install outdoor air hood
7. Install flue hood
8. Install gas piping
9. Install condensate line trap and piping
10. Make electrical connections
11. Install other accessories
FRAME-MOUNTED INSTALLATION — Framemounted applications generally follow the sequence for a curb
installation. Adapt as required to suit specific installation plan.
Step 3 — Inspect Unit — Inspect unit for transportation
damage. File any claim with transportation agency. Confirm
before installation of unit that voltage, amperage and circuit
protection requirements listed on unit data plate agree with
power supply provided.
Step 4 — Provide Unit Support
ROOF CURB MOUNT — Curb should be level. This is
necessary for unit drain to function properly. Unit leveling tolerances are show in Fig. 4. Refer to Accessory Roof Curb Installation Instructions for additional information as required.
Fig. 4 — Unit Leveling Tolerances
Accessory roof curb details and dimensions are shown in
Fig. 5. Assemble and install accessory roof curb in accordance
with instructions shipped with the curb.
NOTE: 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. 5. Improperly applied gasket can also
result in air leaks and poor unit performance.
Install insulation, cant strips, roofing felt, and counter flashing as shown. Ductwork must be attached to curb and not to the
unit. The accessory thru-the-base 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
bly 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 roof curb.
If electric and control wiring is to be routed through the
basepan, attach the accessory thru-the-base service connections
to the basepan in accordance with the accessory installation
instructions.
SLAB MOUNT (HORIZONTAL UNITS ONLY) —
Provide a level concrete slab that extends a minimum of 6 in.
(150 mm) beyond unit cabinet. Install a gravel apron in front of
condenser coil air inlet to prevent grass and foliage from obstructing airflow.
NOTE: Horizontal units may be installed on a roof curb if
required.
ALTERNATE UNIT SUPPORT (IN LIEU OF CURB
OR SLAB MOUNT) — A non-combustible sleeper 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
three equally spaced 4-in. x 4-in. (102 mm x 102 mm) pads on
each side.

exceed 0.35 in. wg (87 Pa) with economizer or 0.45 in. wg
(112 Pa) without economizer. For vertical ducted applications, secure all ducts to roof curb and building structure.
Do not connect ductwork to unit. Fabricate supply
ductwork so that the cross sectional dimensions are equal
to or greater than the unit supply duct opening dimensions
for the first 18 in. (458 mm) of duct length from the unit
basepan. Insulate and weatherproof all external ductwork,
joints, and roof openings with counter flashing and mastic
in accordance with applicable codes.
Ducts passing through unconditioned spaces 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.
CAUTION
Failure to follow this caution may result in damage to roofing materials.
Membrane roofs can be cut by sharp sheet metal edges. Be
careful when placing any sheet metal parts on such roof.
Step 6 — Rig and Place Unit — Keep unit upright and
do not drop. Spreader bars are required. Rollers may be used to
move unit across a roof. Level by using unit frame as a reference. See Table 1 and Fig. 6 for additional information.
Lifting holes are provided in base rails as shown in Fig. 6.
Refer to rigging instructions on unit.
Rigging materials under unit (cardboard or wood to prevent
base pan damage) must be removed PRIOR to placing the unit
on the roof curb. When using the standard side drain connection, ensure the red plug in the alternate bottom connection is
tight. Do this before setting the unit in place. The red drain pan
can be tightened with a
1
/2-in. square socket drive extension.
For further details see Step 11 — Install External Condensate
Trap and Line on page 14.
Before setting the unit onto the curb, recheck gasketing on
curb.
CAUTION
Failure to follow this caution may result in equipment
damage.
All panels must be in place when rigging. Unit is not
designed for handling by fork truck.
POSITIONING ON CURB — Position unit on roof curb so
that the following clearances are maintained:
clearance between the roof curb and the base rail inside the
front and back, 0.0 in. clearance between the roof curb and the
base rail inside on the duct end of the unit. This will result in
the distance between the roof curb and the base rail inside on
the condenser end of the unit being approximately
(6.4 mm).
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 (1220 mm) from electric and gas meters, gas regulators, and gas relief equipment. Minimum distance between
unit and other electrically live parts is 48 inches (1220 mm).
Flue gas can deteriorate building materials. Orient unit such
that flue gas will not affect building materials. Locate mechanical draft system flue assembly at least 48 in. (1220 mm) from
an adjacent building or combustible material.
NOTE: Installation of accessory flue discharge deflector kit
will reduce the minimum clearance to combustible material
to 18 in. (460 mm).
After unit is in position, remove rigging skids and shipping
materials.

Other hardware required to complete the installation of the
gas supply line will include a manual shutoff valve, a sediment
trap (drip leg) and a ground-joint union. A pressure regulator
valve may also be required (to convert gas pressure from
pounds to inches of pressure). The manual shutoff valve must
be located within 6-ft (1.83 m) of the unit. The union, located
in the final leg entering the unit, must be located at least 9-in.
(230 mm) away from the access panel to permit the panel to be
removed for service. If a regulator valve is installed, it must be
located a minimum of 4-ft (1220 mm) away from the unit’s
flue outlet. Some municipal codes require that the manual shutoff valve be located upstream of the sediment trap. See Fig. 17
and 18 for typical piping arrangements for gas piping that has
been routed through the sidewall of the curb. See Fig. 19 for
typical piping arrangement when thru-base is used. Ensure that
all piping does not block access to the unit’s main control box
or limit the required working space in front of the control box.

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:
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 appropriate
straps, hangers, etc. Use a minimum of one hanger every
6 ft (1.8 m). For pipe sizes larger than
1
/2-in., follow rec-
ommendations 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.
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 instructions.
4. Pressure-test all gas piping in accordance with local and
national plumbing and gas codes before connecting piping to unit.

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).
WARNING
Failure to follow this warning could result in personal
injury, death and/or property damage.
• Connect gas pipe to unit using a backup wrench to
avoid damaging gas controls.
• Never purge a gas line into a combustion chamber.
• Never 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.
• Use proper length of pipe to avoid stress on gas control manifold.
NOTE: If orifice hole appears damaged or it is suspected to
have been re-drilled, check orifice hole with a numbered
drill bit of correct size. Never re-drill an orifice. A burr-free
and squarely aligned orifice hole is essential for proper
flame characteristics. See Fig. 20.
Fig. 21 — Condensate Drain Pan (Side View)
The piping for the condensate drain and external trap can be
completed after the unit is in place. See Fig. 22.

Step 12 — Make Electrical Connections
WARNING
Failure to follow this warning could result in personal
injury or death.
Do not use gas piping as an electrical ground. Unit cabinet
must have an uninterrupted, unbroken electrical ground to
minimize the possibility of personal injury if an electrical
fault should occur. This ground may consist of electrical
wire connected to unit ground lug in 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.

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
male spade connector from the 230-v connection and moving it
to the 200-v
1
/4-in. male terminal on the primary side of the
transformer. Refer to unit label diagram for additional information.
Voltage to compressor terminals during operation must be
within voltage range indicated on unit nameplate. See Tables 7
and 8. 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 7 and 8 to determine the percent
of voltage imbalance. 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.
NOTE: Check all factory and field electrical connections
for tightness.

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%. Use the following formula to determine the percentage of voltage imbalance:
% Voltage Imbalance = 100 x
Example: Supply voltage is 230-3-60
AB = 224 v
BC = 231 v
AC = 226 v
Average Voltage = 100 x
Determine maximum deviation from average voltage.

(AB) 227-224 = 3 v
(BC) 231-227 = 4 v
(AC) 227-226 = 1 v
Maximum deviation is 4 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.
