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.
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.
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.
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.
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.
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/national 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 Safety Data Sheets (SDS) and OSHA guidelines for proper PPE.
- When working with or around hazardous chemicals, ALWAYS refer to the appropriate 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 TESTING WITHOUT PROPER ELECTRICAL PPE AND ARC FLASH CLOTHING. ENSURE ELECTRICAL METERS AND EQUIPMENT ARE PROPERLY RATED FOR INTENDED VOLTAGE.
Follow EHS Policies!
Failure to follow instructions below could result in death or serious injury.
- All Trane personnel must follow the company’s Environmental, Health and Safety (EHS) policies when performing work such as hot work, electrical, fall protection, lockout/tagout, refrigerant handling, etc. Where local regulations are more stringent than these policies, those regulations supersede these policies.
- Non-Trane personnel should always follow local regulations.

General Information
These instructions describe converting gas heat unit models from natural gas to propane (LP) gas. Conversion from natural gas to LP gas is a critical procedure, therefore, these instructions must be followed.
Inspection
- Unpack all components of the LP conversion kit.
- Check carefully for any shipping damage and/or missing parts. Contact local Trane Parts Center, if assistance is needed. The gas nipple orifice and spring, if included, must all be replaced for a complete conversion.
Note: This kit contains the correct parts required to complete the LP conversion.

Note: Prior to conversion ensure that gas supply to unit is shutoff and power to unit is disconnected.
- Remove gas valve access panel(s).
- Undo union(s) on gas train.
- Remove nipple as identified in the appropriate figure:
- IntelliPak 1 for 2–stage and modulating, see Figure 2, p. 5 through Figure 4, p. 5.
- IntelliPak 1 for ultra modulating, see Figure 5, p. 5 through Figure 7, p. 6.
- IntelliPak 2 for 2–stage and modulating, see Figure 8, p. 6

- Install the nipple with orifice from the kit. Ensure that the nipple is installed with the orifice closest to the burner. Refer to flow arrows on the nipple.
- Reinstall the gas train by reversing disassembly procedure. Secure all the components.
- For IntelliPak 1 ultra modulating and IntelliPak 2 only, install the LP spring in the pilot pressure regulator. See Figure 9, p. 6

- Attach the LP labels provided in the conversion kit to the burner labels. See Figure 10, p. 6.
Figure 10. Kit label placement on burner
- Attach the Trane LP conversion label (supplied with the unit literature packet) to the inside of the gas heat control panel near the gas heat nameplates. See Figure 11, p. 7.
- Check all piping joints and electrical connections for tightness.
- Turn on the gas supply to the unit.
- Measure the gas pressure. If the pressure exceeds 14” w.c., reset the regulator at the gas supply.
- Restore unit power.
- Check the manifold gas pressure of each gas valve. Follow the appropriate Burner Setup procedure in the Gas Furnace Startup section of the unit IOM (RTSVX072- EN for IntelliPak 1 and RT-SVX073-EN for IntelliPak 2). Set the Seimens controller fan speed, the shutter position, and the ratio regulator turns according to the LP settings tables in the unit IOM’s Installation section for Gas Heat Units.
- Replace access panel(s).
