Introduction
Read this manual thoroughly before operating or servicing
this unit.
Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as
required. Your personal safety and the proper operation of
this machine depend upon the strict observance of these
precautions.
Important Environmental Concerns
Scientific research has shown that certain man-made
chemicals can affect the earth’s naturally occurring
stratospheric ozone layer when released to the
atmosphere. In particular, several of the identified
chemicals that may affect the ozone layer are refrigerants
that contain Chlorine, Fluorine and Carbon (CFCs) and
those containing Hydrogen, Chlorine, Fluorine and
Carbon (HCFCs). Not all refrigerants containing these
compounds have the same potential impact to the
environment. Trane advocates the responsible handling of
all refrigerants-including industry replacements for CFCs
and HCFCs such as saturated or unsaturated HFCs and
HCFCs.
Important Responsible Refrigerant
Practices
Trane believes that responsible refrigerant practices are
important to the environment, our customers, and the air
conditioning industry. All technicians who handle
refrigerants must be certified according to local rules. For
the USA, the Federal Clean Air Act (Section 608) sets forth
the requirements for handling, reclaiming, recovering and
recycling of certain refrigerants and the equipment that is
used in these service procedures. In addition, some states
or municipalities may have additional requirements that
must also be adhered to for responsible management of
refrigerants. Know the applicable laws and follow them.
The three types of advisories are defined as follows:
WARNING Indicates a potentially hazardous
situation which, if not avoided, could
result in death or serious injury.
CAUTIONsIndicates a potentially hazardous
situation which, if not avoided, could
result in minor or moderate injury. It
could also be used to alert against
unsafe practices.
NOTICE Indicates a situation that could result in
equipment or property-damage only
accidents.
WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury. All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements for
field wiring installation and grounding as described in
NEC and your local/state electrical codes.
WARNING
Personal Protective Equipment (PPE)
Required!
Failure to wear proper PPE for the job being undertaken
could result in death or serious injury. Technicians, in
order to protect themselves from potential electrical,
mechanical, and chemical hazards, MUST follow
precautions in this manual and on the tags, stickers,
and labels, as well as the instructions below:
• Before installing/servicing this unit, technicians
MUST put on all PPE required for the work being
undertaken (Examples; cut resistant gloves/sleeves,
butyl gloves, safety glasses, hard hat/bump cap, fall
protection, electrical PPE and arc flash clothing).
ALWAYS refer to appropriate Material Safety Data
Sheets (MSDS)/Safety Data Sheets (SDS) and OSHA
guidelines for proper PPE.
• When working with or around hazardous chemicals,
ALWAYS refer to the appropriate MSDS/SDS and
OSHA/GHS (Global Harmonized System of
Classification and Labelling of Chemicals) guidelines
for information on allowable personal exposure
levels, proper respiratory protection and handling
instructions.
• If there is a risk of energized electrical contact, arc, or
flash, technicians MUST put on all PPE in accordance
with OSHA, NFPA 70E, or other country-specific
requirements for arc flash protection, PRIOR to
servicing the unit. NEVER PERFORM ANY
SWITCHING, DISCONNECTING, OR VOLTAGE

Pre-Installation
Receiving and Handling
Inspection
Upon delivery, thoroughly inspect all components for any
shipping damage that may have occurred, and confirm
that the shipment is complete. See “Receiving Checklist”
for detailed instructions.
Note: Delivery cannot be refused. All units are shipped
F.O.B. factory. Trane is not responsible for shipping
damage.
Packaging/Shipping
Gas heat sections arrive at the jobsite with an integral base
frame for the purpose of mounting units to a
housekeeping pad or roof curb. The base frame variables
in height from the standard 2.5 inches to 8 inches.
Outdoor gas heat sections ship with wooden blocks
fastened under the base channel. The blocks elevate the
section for shipping protection and ease of handling.
Leave the wooden blocks attached until the section is
placed in its final position to avoid bending the base
channel during rigging and handling.
Protective Covering
The large openings of the gas heat section are covered
with shipping protection parts. The parts are held in place
by sheet metal screws. Leave the covering attached to the
section until it is ready to install to prevent debris from
entering the section.
Flue Stack
A stainless-steel flue stack is provided with outdoor air
handlers. It ships inside the gas heat section or in one of
the other sections of the air handler, and must be mounted
on the flue opening on the side of the unit.
Hardware Kits
Hardware kids ship inside the air handler fan section in a
plastic bag or cardboard box. This kit contains gasketing
and screws. For outdoor units, roof joint connection strips
and wall panel seam caps are included. These are used
when fastening the gas heat section to the air handler.
Keep the hardware with the gas heat section until it is
ready to install.
Rain Hood
A rain hood is provided for outdoor units and is shipped
attached. Rain hoods for units with hurricane certifications
are shipped on a separate wood skid. A kit containing
mounting hardware ships inside the gas heat section and
must be removed before assembly to the air handler.
Instruction Manuals
Individual instruction manuals for all of the gas train
components (such as flame-control relay valves, pressure
switches, and actuators) ship inside the piping vestibule.
Retain these manual for future repair or troubleshooting.
Handling
The gas heat section is designed with the necessary
number of lift points for safe installation. The lift points are
designed to accept standard rigging devices and are
removable after installation.
Indoor sections size 4 to 30 will be shipped with a shipping
skid designed for forklift transport. If shipped on a skid, do
not remove the gas heat section from the skid at this time.

Dimensions and Weights
Service Clearances
A minimum clearance of the section width plus 12 inches
on the access door side of the gas heat section is
recommended for routine maintenance. This clearance
provides enough room to replace the heat exchanger in
the event of failure. The section side panels must be
removed to access the heat exchanger. Refer to the
following figure for service clearance recommendations
for the air handler.
Note: At a minimum, the clearance dimensions listed in
table below are recommended on one side of the
unit for regular service and maintenance. Refer to
as-built submittal for locations of items such as
filter access doors, coil, piping connections, motor
locations, hoods, pipe cabinets, etc. Sufficient
clearance must be provided on all sides of unit for
removal of access panels, plug panels, or section-
to-section attachment brackets. Clearance for
starters, VFDs, or other high-voltage devices must
be provided per NEC requirements. For specific
dimensional and weight information, refer to the
unit submittals. The dimensions and weights in this
manual are approximate. Trane has a policy of
