SAFETY CONSIDERATIONS

Installing and servicing air conditioning equipment can be hazard­ous due to system fuels. Only trained and qualified personnel
should install, service, or repair air conditioning equipment.

Untrained personnel can perform basic maintenance functions
such as cleaning coils, or cleaning and replacing filters. All other
operations should be performed by trained service personnel.
When working onair conditioning equipment, observe precautions
in the literature, on tags, and on labels attached to the unit.

Recognize safety information. This is the safety-alert symbol
When you see this symbol on the unit and in instructions or
manuals, be alert to the potential for personal injury.

Understand the signal words DANGER, WARNING, and CAU­TION. These words are used with the safety-alert symbol. DAN­GER identifies the most serious hazards which will result in severe
personal injury or death. WARNING signifies a hazard which
could result in personal injury or death. CAUTION is used to
identify unsafe practices which would result in minor personal
injury or product and property damage. NOTE is used to highlight
suggestions which will result in enhanced installation, reliability,
or operation.

Follow all safety codes. Wear safety glasses and work gloves.
Have a fire extinguisher available.

Before converting a unit to LP, remove the burner assembly
and inspect the heat exchanger tubes. If there are V-shaped
NOx baffles installed in the firing tubes (See Fig. 1). THEY

MUST BE REMOVED PRIOR TO CONVERTING
THIS UNIT TO LP. Discard the baffles after removal.

This unit is designed to operate at 3.5 in. wg (±0.3 in. wg) of
manifold pressure with liquid propane (LP) gas. Exceeding
this pressure may result in explosion, injury or death.

→

These instructions cover the installation of a liquid propane
conversion kit on models 48GS, 582A, PY1P-B, 48GX, 583A,
PY2P-B, 48GP, and 583B that are equipped with a White Rodgers
combination automatic gas valve regulator.

This kit is applicable to units with heating inputs from 60,000 to
130,000 Btu/hrinstalled at standard altitudes from 0 ft to 2000 ft.

It cannot be used for high altitude installations or on units with
heating inputs of 40,000 Btu/hr. High altitude conversions
(2001–6000 ft) should use kit #CPLPCONV007A00. All conver­sions of 40,000 Btu/hr units should use Kit
#CPCLPCONV008A00 (applicable for any altitude from 0 ft to
6000 ft).

C00151

This conversion kit is to be installed by qualified service
personnel in accordance with these instructions and all codes
and requirements of the authority having jurisdiction, and in
Canada, in accordance with the requirements of the
CAN/CGA (Canadian Gas Association) B149.2 Installation
Code. Failure to follow these instructions could result in
serious injury, property damage or death. The qualified
agency performing this work assumes responsibility for this
conversion.

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

1. Turn off gas supply first, then power to unit.

2. Remove the front access panel from unit.

3. Disconnect the gas pipe from the gas valve.

4. Disconnect orange sparker cable at the ignition control.

5. Disconnect yellow flame sensor wire from the ignition con­trol.

6. Remove the screw securing the brown wire from the burner
assembly and the green wire from the induced-draft motor at
the sheet metal partition. Save screw.

7. Disconnect the gray and brown wires from the gas valve, and
remove blue wires from the rollout switch.

and slide out the entire burner rack assembly from unit. Save
screw.

9. Inspect the inlet of the heat exchanger tubes for presence of
V-shaped NOx baffles (see Fig. 1.) If baffles are present they
must be removed prior to converting unit for LP gas. Slide
the baffles out of the tubes (on some models a retaining clip
must be released). IMPORTANT: If it is expected that this

unit will be converted back to natural gas at a later time,
these baffles should be retained for reuse. Otherwise the
baffles may be discarded.

10. Using a 5/16 in. nut driver, remove the four screws securing

the manifold/gas valve assembly to the burner assembly. Save
these screws.

11. Remove the natural gas orifices from the manifold using a
9/16 in. wrench and install the correct LP gas orifices in the
manifold (See Table 2 to select correct orifice size based on
input. See Fig. 2 for orifice installation).

12. Replace the manifold/gas valve assembly into the burner
assembly using the four screws saved from Step 10.

13. Reconnect the blue wires to the rollout switch and reinstall
rollout switch.

14. Reconnect the gray wire removed in Step 7 to terminal 1 (M1)
of the gas valve. Reconnect the brown wire to terminal 2 (C2)
on the main gas valve.

15. Reconnect orange sparker cable and the yellow flame sensor
wires at the ignition control.

16. Slide burner rack assembly into basepan. Align burner rack
with screws on sheet metal partition and slide assembly back
tight to the partition. Replace the screw attaching the burner
rack to the basepan, removed in Step 8.

17. Reconnect the brown wire from the burner assembly and the
green wire from the induced-draft motor to the sheet metal
partition.

18. Remove the 1/8” pipe plug on the gas manifold and connect a
pressure manometer.

19. Reconnect electrical power and gas supply to the unit.

20. Fire unit and verify proper ignition. Verify that the pressure
manometer reads 3.5–in. ± 0.3–in. wc. If the pressure is
outside this range, adjust the gas valve settingby removing the
slotted brass fitting and turning the nylon adjustment screw.
Replace brass fitting.

21. Turn off unit, remove pressure manometer and replace the
1/8–in. pipe fitting on the gas manifold.

22. Attach warning label (P/N 48GS500615) to visible side of gas
valve.

23. Attach conversion label (P/N 48GS500614) above unit rating
plate on exterior of unit.

24. Attach completed conversion responsibility label (see Fig. 3,
P/N 48SS500283) inside service access panel.

25. IMPORTANT: Restart unit and leak check all gas connec­tions including the main service connection, gas valve, gas
spuds, and manifold pipe plug.

26. After all leaks are eliminated, replace service panel.
