The input rating for altitudes above 2000 ft must be reduced by 4 percent for each 1000 ft above sea level. Consult the current edition of the National Fuel Gas Code NFPA No. 54/ANSI Z223.1, Part 8.1 and Appendix F, Table F-4, for input adjustment for high altitude. In Canada, the adjustments must be made in accordance with the CAN/C.G.A.-B149 Installation Code. 8. Reinstall burners, from right to left, and burner bracket. Ensure that burner crossovers are aligned. See Fig. 4 and 5 for proper orientation of ignitor and burners. Ensure wiring is routed properly; see label on burner enclosure front regarding wiring. & ~o r 11/32" IGNITOR ASSEMBLY A91064 Fig. 4—Position of Burner and Ignitor (Side View) A91064 Fig. 3—Combustion-Air Diffuser Location A84153 Fig. 5—Position of Burner and Ignitor (Top View) WA 9. Reinstall combustion-air diffuser with vents to front. (See Fig. 3.) 10. Do not reinstall burner enclosure front at this time. Step 2—Conversion of Gas Valve and Inlet Gas Pressure Check 1. Remove regulator seal cap. (See Fig. 6.) REGULATOR SEAL CAP -REGULATOR ADJUSTMENT SCREW REGULATOR SPRING (PROPANE - WHITE, 6 TURNS NATURAL - SILVER, 10 TURNS) CONTROL KNOB GAS PRESSURE REGULATOR BURNER ENCLOSURE REFERENCE PRESSURE TAP MANIFOLD PRESSURE TAP Fig. 6—White-Rodgers 36E Gas Valve A90224 2. Remove regulator adjustment screw and natural gas regulator spring (silver). 3. Install white propane regulator spring provided in kit. 4. Replace regulator adjustment screw. Do not reinstall regulator seal cap at this time. 5. Remove 1/8-in. pipe plug from inlet pressure tap on gas valve. (See Fig. 7 or 8.) PRESSURE SWITCH (LGPS) A88209 Fig. 7—Installation of Pressure Switch (Downflow Furnace) 6. Check inlet propane gas pressure as follows: A87420 Fig. 8—Installation of Pressure Switch (Upflow Furnace) NOTE: This kit is to be used only when inlet propane gas pressure is between 11.0-in. wc and 13.6-in. wc. a. Attach manometer at inlet pressure tap on gas supply side of furnace gas valve. A CAUTION Do not operate furnace more than one minute to check inlet gas pressure since conversion is not complete at this time. b. Set room thermostat to “call for heat.” c. Turn gas supply manual shut-off valve ON. d. Turn furnace gas valve control knob ON. e. Turn ON electrical supply to furnace. f. When burners have ignited, confirm proper inlet gas pressure. g. Turn furnace gas valve control knob OFF. h. Turn gas supply manual shut-off valve OFF. i. Turn OFF electrical supply to furnace. j. Remove manometer. NOTE: Use a propane gas resistant pipe dope. Do not use Teflon tape. NOTE: The inlet gas pipe must be disconnected from the valve so the pressure switch can be installed. 7. Apply pipe dope sparingly to both ends of pipe nipple (provided in kit) and install nipple in 1/8-in. tapped opening in gas valve; finger tighten. (See Fig. 7 or 8.) 8. Apply pipe dope sparingly to threaded end of street elbow (provided in kit). Install elbow on nipple; finger tighten. Use small pipe wrench for final tightening. 9. On upflow furnaces, point male end of street elbow vertically up and tilted back to clear control compartment access door. (See Fig. 8.) 10. On downflow furnaces, point male end of street elbow towards front of gas valve. (See Fig. 7.) 11. Apply pipe dope sparingly to end of inlet gas pipe and reconnect pipe to gas valve. 12. Install propane pressure switch (provided in kit) on street elbow. After switch has been finger tightened, use small wrench on base of pressure switch for final tightening. When pressure switch is tight, switch terminals should point toward right side of furnace. Step 3—Wiring 1. Disconnect yellow wire from heat exchanger differential pressure switch (PRS) on inducer housing; add splice connector to this wire. 2. Connect uninsulated terminal of one yellow wire (provided in kit) to the splice connector; connect other end to terminal C on low gas pressure switch (LGPS) on gas valve. 3. Connect insulated terminal of second yellow wire (provided in kit) to terminal NO on pressure switch LGPS; connect other end to pressure switch PRS. 4. Route yellow wires along wire harness; secure wires with wire tie provided. Step 4—Check Furnace Operation and Make Necessary Adjustments 1. Ensure gas and electrical supplies to furnace are OFF. 2. Attach manometer at manifold pressure tap on downstream side of gas valve. 3. Set room thermostat to “£all for heat.” 4. Turn ON gas supply manual shut-off valve. A WARNING Never use a match or other open flame to check for leaks. Use a soap-and-water solution. Failure to follow this warning could result in personal injury or death. 5. Turn furnace gas valve control knob ON and check all threaded pipe connections for gas leaks. 6. Turn ON electrical supply to furnace. 7. When hot surface ignitor glows, check it for cracks in silicon carbide. 8. When burners ignite, check manifold orifices for gas leaks. 9...
