TABLE 1—INTERMITTENT PILOT IGNITION MODULES. IGNITER- 100 SENSOR TYPE PREPURGE PERCENT LOCKOUT IGNITION MODEL TYPE OF GAS TIMING SHUTOFF TIMING SEQUENCE a S8600A, Separate Natural None No No Spark on until pilot S8610A lightoff or manual S8600F, Combination shutoff; pilot valve S8610F open until manual shutdown.
2 CORROSIVE CHEMICALS Corrosive chemicals can also attack the module and gas control and eventually cause a failure. Where chemicals may be used routinely for cleaning, make sure the cleaning solution cannot reach the controls.
We recommend mounting the module with the terminals down to protect them from dripping water and dust. It can also be mounted with the terminals on either side. DO NOT MOUNT with terminals pointing up. Fasten securely with four No. 6-32 machine or No.
4 Ground Control System The igniter, flame sensor and ignition module must share a common ground with the main burner. Use thermo- plastic insulated wire with a minimum rating of 105 ° C [221 ° F] for the ground wire; asbestos insulation is not accept- able.

call for heat. ❏ Make sure pilot lights smoothly when gas reaches the pilot burner. ❏ Make sure main burner lights smoothly without flash- back. ❏ Make sure burner operates smoothly without floating, lifting, or flame rollout to the furnace vestibule or heat buildup in the vestibule.
13 69-0463 TRIAL FOR IGNITION Pilot Ignition Following prepurge timing (S8660, S8670), or on the call for heat (S8600, S8610), the module energizes the first main valve operator. The first main valve opens, which allows gas to flow to the pilot burner.
14 WARNING When performing the following steps, do not touch stripped end of jumper or SPARK terminal. The ignition circuit generates over 10,000 volts and electrical shock can result. ❏ Energize the module and immediately touch one end of the jumper firmly to the GND terminal on the module.
15 69-0463 • Make sure electrical connections are clean and tight. Replace damaged wire with moisture-resistant No. 18 wire rated for continuous duty up to 105 ° C [221 ° F]. • Check for cracked ceramic insulator, which can cause short to ground, and replace igniter-sensor if neces- sary.
Fig. 15 — S8660, S8670 troubleshooting guide. 16 Check continuity of ignition cable and ground wire. NOTE: If ground is poor or erratic, shutdowns may occur occasionally even though operation is normal at the time of checkout. If checks are okay, replace module.

19 69-0463 EXHIBIT A RECOMMENDED PROCEDURE FOR SAFETY INSPECTION OF AN EXISTING APPLIANCE INSTALLATION AS A PRELIMINARY STEP TO APPLYING AN AUTOMATIC INTERMITTENT PILOT SYSTEM The following procedure is intended as a guide to aid in determining that an appliance is properly installed and is in a safe condition for continuing use.
EXHIBIT B PROCEDURE FOR INSTALLING AUTOMATIC INTERMITTENT PILOT SYSTEMS Prior to beginning this procedure, a preliminary ex- amination of the appliance and the automatic intermit- tent pilot system should be made to determine that the automatic intermittent pilot system can be properly applied to the appliance.
