The kit can be used to convert propane gas 100% shutoff IID controls to natural 100% shutoff IID. It is designed for use in furnaces with 30,000- thru 100,000-Btuh nominal output capacity. These furnaces are to be installed only within California. NOTE: The definition of 100% shutoff refers to automatic shutoff of the pilot and main burner gas when the ignition source is not proven. NOTE: Read the entire instructions before starting the installation. There are additional parts shipped in the kit. When the installation is complete, discard the unused parts. A CAUTION Do not use this kit to convert 58DR and 58GS units to natural gas applications. A WARNING Improper installation, adjustment, alteration, service, maintenance, or use can cause carbon monoxide poisoning, explosion, fire, electrical shock, or other conditions which may cause personal injury or property damage. Consult a qualified installer, service agency, local gas supplier, or your Distributor or Branch for information or assistance. The qualified installer or agency must use only factory-authorized kits or accessories when modifying this product. New NOx burners must be installed along with this kit. The burners are not supplied with the kit. Order the required number of burners for the furnace being converted. Order burner P/N 309472-751.

A failure to follow instructions could result in serious injury or property damage. The qualified agency performing this work assumes responsibility for this conversion. A. Installation of Pilot Orifice 1. Turn off gas and electric supplies to furnace. 2. Remove control access door. 3. Disconnect pilot gas tube from gas valve. 4. Unplug electrode wire from spark generator. 5. Remove pilot assembly from burner and furnace. 6. Using backup wrench, remove gas supply tube from pilot. 7. Remove and discard propane gas pilot orifice (silver, 5/8-in. long, 0.012-in. diameter orifice, knurlj gas supply opening of pilot.

Install new natural gas pilot orifice (silver, 1/2-in. long, 0.018-in. orifice diameter). 9. Reinstall pilot gas supply tube on pilot. When tightening pilot tube, use backup wrench and turn pilot so that it will be on the same angle as before. Do not reinstall pilot at this time. B. Installation of Main Burner Orifices 1. Remove secondary air shield. 2. Remove main burners from manifold. 3. Remove and discard No. 55 (or field-installed per local application) orifices from manifold. 4. Install No. 45 main burner orifices provided in kit. Finger-tighten orifices at least one full turn so as not to cross-thread, then tighten with wrench. There are enough orifices in each kit for the largest furnace. Discard extra orifices. The full input rating with No. 45 main burner natural gas orifices is approved for altitudes up to 2000 ft. The input rating for altitudes above 2000 ft must be reduced by 4% 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. 5. Install new burners with NOx reduction screens on manifold. See Figs. 2 and 3 for proper orientation of burners and pilot. 6. Reinstall pilot assembly. 7. Reconnect pilot supply tube to gas valve. 8. Reconnect electrode wire to spark generator. 9. Reinstall secondary air shield. C. Conversion of Gas Valve and Inlet Gas Pressure Check 1. Remove regulator seal cap. See Fig. 4 for BDP 646A or Fig. 5 for White-Rodgers 36E Gas Valve. 2. Remove adjustment screw and propane gas regulator spring (red for 646A and white for 36E). 3. Install proper natural gas regulator spring (silver) provided in kit, in proper gas valve. See Table 1. 4...
