Use a soap-and-water solution. A failure to heed this warning could result in personal injury or death. 4. Turn gas supply manual shut-off valve on and check inlet pressure tap plug for leaks. 5. Turn furnace gas valve control knob to ON and check all threaded pipe connections for gas leaks. 6. Turn on electrical supply. 7. When pilot ignites, check pilot gas-supply tube connections for leaks. When main burners ignite, check manifold orifices for gas leaks. 8. Determine gas input: a. Turn off all other gas appliances and pilots. b. Measure time (in seconds) for gas meter test dial to complete one revolution. c. Refer to Table 2 for cubic ft of gas per hour. d. Multiply cubic ft/hour by Btu cubic ft. Obtain heating value from local gas utility. NOTE: Be sure heating value of gas used for calculations is correct for your altitude. Consult local gas utility for altitude adjustment of gas heating value. High altitude: 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. e. Refer to unit rating plate for gas input rate. The measured input must be within 2 percent of the rating plate input. EXAMPLE: Btuh heating input = Btu/cubic ft times cubic ft/ hour Heating value of gas = 1070 Btu/cubic ft. Time for one revolution of 2-cubic-ft dial = 72 seconds Gas rate = 100 cubic ft/hour (from Table 2) Btu heating input = 1070x 100 = 107,000 Btuh 9. To adjust input rate: a. Remove cap that conceals adjustment screw for gas valve regulator. b. Turn adjustment screw either counterclockwise (out) to decrease input or clockwise (in) to increase rate. When adjusting input rate, do not set manifold pressure above 3.8 or below 3.2-ins. wc. Make any major adjustments by changing main burner orifices.

Measure adjusted gas input rate using method outlined in step 8. d. Replace regulator adjustment screw seal cap. 10. Inspect burner and pilot flame. The main burner flame should be clear blue, almost transparent. The pilot flame should be soft blue in color and it must provide good impingement on the pilot-sensing element. The flame should extend above the burner carryover port to provide proper burner ignition. See Figs. 2 and 3. When the pilot flame requires adjustment: a. Locate adjustment screw marked PILOT ADJ on top of gas valve. See Figs. 4 and 5. b. Remove cap and turn adjustment screw clockwise to decrease pilot gas flow. Turn screw counterclockwise to increase pilot gas flow. c. When proper adjustment is obtained, replace screw cap. 11. Turn furnace gas valve control knob to OFF. 12. Remove manometer and replace manifold pressure tap plug. 13. Turn furnace gas valve control knob to ON. 14. With main burners ignited, check pressure tap plugs for gas leaks. E. Check Lockout Timer Module (LOD) Operation 1. Turn ofl electrical supply. 2. With furnace off, remove wire from terminal No. 5 of gas valve. 3. Set room thermostat to “call for heat.” 4. Turn on electrical supply. 5. Let pilot spark until lockout timer breaks spark generator circuit (approximately 5 minutes). 6. Replace wire on terminal No. 5 of gas valve. 7. Electrically reset lockout timer by setting room thermostat below room temperature for approximately 30 seconds. 8. Sign and date conversion label P/N 310167-312 provided in kit, and attach to outside of blower compartment door. 9. ...
