SAFETY WARNING
Only qualified personnel should install and service the equipment. The installation, starting up, and servicing
of heating, ventilating, and air-conditioning equipment can be hazardous and requires specific knowledge and
training. Improperly installed, adjusted or altered equipment by an unqualified person could result in death or
serious injury. When working on the equipment, observe all precautions in the literature and on the tags,
stickers, and labels that are attached to the equipment.

Warnings, Cautions and Notices
Warnings, Cautions and Notices. Note that warnings, cautions and notices appear at
appropriate intervals throughout this manual. Warnings are provided to alert installing contractors
to potential hazards that could result in personal injury or death. Cautions are designed to alert
personnel to hazardous situations that could result in personal injury, while notices indicate a
situation that could result in equipment or property-damage-only accidents.
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 such as HCFCs and HFCs.
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. 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.
WARNING
Contains Refrigerant!
System contains oil and refrigerant under high pressure. Recover refrigerant to relieve pressure
before opening the system. See unit nameplate for refrigerant type. Do not use non-approved
refrigerants, refrigerant substitutes, or refrigerant additives.
Failure to follow proper procedures or the use of non-approved refrigerants, refrigerant
substitutes, or refrigerant additives could result in death or serious injury or equipment damage.
ATTENTION: Warnings, Cautions and Notices appear at appropriate sections throughout
this literature. Read these carefully.
WARNING: Indicates a potentially hazardous situation which, if not avoided, could
result in death or serious injury.
CAUTION: Indicates 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.

Warnings, Cautions and Notices
WARNING
Proper Field Wiring and Grounding Required!
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. Failure to follow codes could result in death or serious injury.
WARNING
Personal Protective Equipment (PPE) Required!
Installing/servicing this unit could result in exposure to electrical, mechanical and chemical
hazards.
• Before installing/servicing this unit, technicians MUST put on all Personal Protective
Equipment (PPE) recommended for the work being undertaken. ALWAYS refer to appropriate
MSDS and OSHA guidelines for proper PPE.
• When working with or around hazardous chemicals, ALWAYS refer to appropriate MSDS and
OSHA guidelines for information on allowable personal exposure levels, proper respiratory
protection and handling recommendations.
• If there is a risk of arc or flash, technicians MUST put on all Personal Protective Equipment (PPE)
in accordance with NFPA70E or other country-specific requirements for arc/flash protection
PRIOR to servicing the unit.
Failure to follow recommendations could result in death or serious injury.

General Information
Description
The gas heat section consists of a drum-and-tube heat exchanger, burner, gas train components,
and a control panel for electrical connections. It is an integral part of the entire air-handling system.
An access door is provided for service and maintenance of the burner and gas train components.
The gas heat section must be in a blow-thru position downstream from the supply fan.
Downstream sections must be separated by a blank access section and discharge temperatures
must be controlled so as not to exceed the temperature limits of components in the downstream
sections.
Depending on the heater size, an external vestibule that extends the width of the gas heat section
may be used to house the burner and gas train components (see Figure 2). The external vestibule,
if required, ships attached to the gas heat section. Some heaters have gas train components in an
internal vestibule (see Figure 3). Refer to Tab le 2 for vestibule locations.

Pre-Installation
Gas Heat Sections Upon Arrival at Jobsite
Gas heat sections arrive at the jobsite with an integral baseframe for the purpose of mounting units
to a housekeeping pad or roof curb. The baseframe variables in height from the standard 2.5-
inches to 8 inches.
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 3-30 will also be shipped with a shipping skid designed for forklift transport.
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.
Flue Stack for Outdoor Air Handler
A stainless-steel flue stack is provided with outdoor air handlers. It ships inside the gas heat section
and must be mounted on the flue opening on the side of the unit. The flue stack must be installed
on the gas heat section before assembling the gas heat section to the air handler.
Note: It is very difficult to remove the flue from inside the unit once the unit is assembled.
Flue Stack for Indoor Air Handler
Indoor air handlers require a field-engineered and field-installed flue stack. Local codes and
practices vary throughout the country. The engineer should size the flue based on MBh output,
horizontal and vertical run lengths, type of flue material, NFPA 54 Fuel Gas Code, and local codes.
The flue should be designed for 800 degrees F (430 degrees C). If horizontal runs over 20 feet or
other static-increasing transitions are necessary, a flue booster fan will be required.
NOTICE:
Equipment Damage!
Do NOT use type B flue stacks with this product as they are not suitable for the flue gas
temperatures. Using a Type B flue stack could result in equipment or property damage.
Protective Covering
The large openings of the gas heat section are protected by an Oriented Strand Board (OSB) panel
covering. The OSB panel is 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.
Hardware Kits
Hardware kits 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 with internal vestibules. The rain hood is 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 manuals for
future repair or troubleshooting.
