If fuse replacement is required, use ONLY a 3-amp fuse of identical size. PILOT — Check the pilot and clean if necessary at the beginning of each heating season. The pilot flame should be high enough for proper impingement of the flame-sensing element (or thermocouple) and to light the burners. Remove the accumulation of soot and carbon from the flame-sensing element (or thermocouple). Refer to Fig. 7 for proper location of pilot on burner assembly. TROUBLESHOOTING — Page 8 contains a troubleshooting chart. This chart can be a useful tool in isolating furnace operation problems. Beginning with the word ‘‘Start,’’ answer each question and follow the appropriate arrow to the next item. The chart will help identify the problem or failed component. After replacing any component, verify correct operating sequence as indicated by bold arrows. 5 FIELD 24-VOLT WIRING FIELD 115-, 208/230-, 460-VOLT WIRING FACTORY 24-VOLT WIRING FACTORY 115-VOLT WIRING THERMOSTAT W RGY 208/230- OR 460-VOLT THREE PHASE 208/230- VOLT SINGLE PHASE shown for proper operation. 115-VOLT FIELD- SUPPLIED FUSED DISCONNECT CONTROL AUXILIARY J-BOX BOX 24-VOLT TERMINAL BLOCK TWO-WIRE HEATING- ONLY FOUR WIRE FIELD-SUPPLIED FUSED DISCONNECT CONDENSING UNIT TWO WIRE NOTE: If any of the original wire, TERMINALS FURNACE R G C GND GND WHT BLK WHT BLK as supplied, must be replaced, use NOTE: Connect Y-terminal as GND same type or equivalent wire.
