Trane BAYLPKT101C Conversion Kit

Trane BAYLPKT101C Conversion Kit

Trane

The Trane BAYLPKT101C LP Conversion Kit is the factory natural gas to propane (LP) conversion kit for Trane and American Standard single packaged gas/electric units in the 64K, 70K and 96K heating sizes. It is the current replacement for the discontinued BAYLPKT101A. A packaged unit leaves the factory set up for natural gas, and firing propane through natural gas burner orifices overfires the burners and stresses the heat exchanger, so the kit changes the two parts that meter the fuel: the #52 drill-size LP orifices and the propane regulator springs for the gas valve. An LP nameplate and a round LP conversion label are supplied to mark the unit as converted for the next technician.

Trane’s installer’s guide PKGR-SVN005B-EN covers YC packaged gas/electric, A5PG packaged and DC dual fuel units from 2 to 5 ton, and it picks the kit by heating size rather than by tonnage. The BAYLPKT101C is the kit for the 64K, 70K and 96K models, which includes the 70K 5YCC4030A1070A, 5YCC4036A1070A and 5YCC4048A1070A, the three-phase 5YCC4036A3070A, 5YCC4048A3070A, 5YCC4036A4070A and 5YCC4048A4070A, and the A5PG3030A1070A and A5PG3036A1070A. Its neighbors in the line are separate kits: BAYLPKT100C for 40K and 120K (#49 orifices), BAYLPKT102C for 75K (#50), BAYLPKT103A for 60K and 90K (#53) and BAYLPKT104A for 115K (#51). Check the heating input on the unit rating plate before ordering, because the orifice size is what sets the correct input. After conversion, Trane lists a target manifold pressure of 10 in. W.C. on single-stage units and 5.8 in. W.C. low fire with 10 in. W.C. high fire on two-stage units, fed by an incoming supply of 11 to 13 in. W.C.

The conversion is a critical gas procedure, so it belongs to a qualified service agency working from the guide. Shut off the gas and power, pull the controls/heat access panel, and unplug the connector at the gas valve before touching the manifold, since leaving it connected can damage the valve terminals. Measure and note the orifice depth before pulling the natural gas orifices, then seat the #52 LP orifices to that same depth. On a White-Rodgers 36G/H/J valve, replace the regulator spring with a kit spring (one on single-stage valves, one per stage on two-stage valves, keeping the spare with the unit); a Sanhua valve needs no spring change. Apply the labels, leak-test every joint with soap solution, set high fire first and then low fire, and finish by checking for soft, steady blue flames with no lifting or heavy yellow tipping. Above 2000 feet, derate the application 4% per 1000 feet.

Key Benefits

  • Heating-size match: One kit covers the 64K, 70K and 96K sizes with the #52 orifices Trane specifies, so the converted unit fires at its rated BTU input.
  • Both gas valve brands: The kit carries propane springs for White-Rodgers valves, while Sanhua valves convert with the orifices alone.
  • Labeled conversion: The LP nameplate and conversion label leave a visible record beside the unit nameplate and on the gas valve.
  • Current OEM number: Replaces the discontinued BAYLPKT101A and is the number Trane lists in the PKGR-PSD005B-EN submittal and the PKGR-SVN005B-EN installer’s guide.

Common Questions

  • Does the BAYLPKT101C replace the BAYLPKT101A? Yes. The BAYLPKT101A is discontinued, and the BAYLPKT101C is the current kit for the 64K, 70K and 96K models. Units in the 60K and 90K sizes go with the BAYLPKT103A instead.
  • Do I have to change the gas valve spring? Only on White-Rodgers valves, which use the propane springs supplied in the kit. Units fitted with a Sanhua gas valve do not need a regulator spring replaced, but the LP orifices and the manifold pressure setting still apply.
  • What pressures should I see after converting? Trane calls for 11 to 13 in. W.C. incoming supply pressure and a manifold setting of 10 in. W.C. on single-stage units, or 5.8 in. W.C. low fire and 10 in. W.C. high fire on two-stage units. If the supply differs from the unit nameplate value, contact the LP gas supplier.
