Recheck ignition sequence as follows: • Reconnect main valve wire. • Set thermostat to call for heat. • Watch ignition sequence at burner. • If spark still does not stop after pilot lights, replace ignition module. • If main burner does not light or if main burner lights but system locks out, check module, ground wire, and gas control as described in control module instructions. 3 60-0653—8 Fig. 7—Example of unsatisfactory pilot flames.

Assure that ignition cable is not in contact with metal surfaces. 2. Assure that ignition cable is not more than 3 feet [1 m] long. 3. Assure connections to the ignition module stud terminal and the igniter-sensor are clean and tight. 4. Check electrical continuity of ignition cable. CHECK GROUNDING 1. If ground is poor or erratic, safety shutdown will occur. Therefore, if nuisance shutdowns are reported, check the ground precautions in Wire Igniter-Sensor section. 2. If leadwire is damaged or deteriorated, use no. 14 to 18 gauge, moisture-resistant, thermoplastic, insulated wire with 221° F [105° C] minimum rating as replacement. 3. Excessive temperature at the ceramic flame rod insulator will permit electrical leakage to ground. a. If bracket is bent, bend it back to correct position. b. If insulator is cracked, replace pilot burner/ igniter-sensor. TEST SAFETY LOCKOUT Refer to appliance manufacturer instructions to test for proper safety lockout times.
