INTERMITTENT PILOT INSTRUCTION

FOR HONEYWELL SYSTEM

STARTING BURNER

1.Depress the gas valve control knob on the combination gas valve and turn to “OFF”. See Figure 9.

2.Set the room thermostat above room temperature and wait five (5) minutes.

3.Set thermostat below room temperature.

4.Turn gas control valve knob to “ON”.

5.Set room thermostat higher than room temperature so that the burner will start.

SHUTTING DOWN THE BURNER

1.Depress the gas valve control knob on the combination gas valve and turn to “OFF”.

2.Turn off electrical supply.

OPERATION

FIRST STAGE -- TRIAL FOR PILOT IGNITION

On every call for heat (system start), the S8600 performs an internal safe-start check. A system start is prevented if the check shows that a flame-simulating condition is present..

During a normal start, the S8600 opens the first operator in the gas control. This allows gas to flow to the pilot burner. Simultaneously, the electronic spark generator in the S8600 produces a 15,000 volt spark pulse output. This voltage produces a spark at the pilot burner ignitor-sensor rod, igniting the gas flowing around the electrode. If the pilot flame is not detected during the trial for pilot ignition, the S86E an F will continue trying for pilot ignition until a flame is established. The S86G and H contain a safety locknut timer to limit the trial for pilot ignition period.

SECOND STAGE -- MAIN BURNER OPERATION

When the pilot flame is established, a flame rectification circuit is completed to the burner ground. The S8600 flame sensing circuit detects the flame current and shuts the spark generator off. At the same time the second operator (main) is opened in the gas control, allowing gas flow to the main burner. The pilot flame ignites the main burner conventionally. On the S86G and H the flame current also holds the safety lockout timer in the reset, or normal, operating condition.

SAFETY LOCKOUT TIME (S8600 only)

The safety lockout timer circuit starts timing the moment the trial for pilot ignition starts. When the timing period runs out, the trial for ignition ends, and the control module goes into lockout. Before another attempt to start can be made, the S8600 must be reset. Reset by adjusting the thermostat or controller below room temperature, or to its “OFF” position. An alternate method is to shut the system power “OFF”. Wait at least one (1) minute, then turn the system “ON”. If normal ignition does not occur, use the troubleshooting table to determine the problem.

SERVICE

PRELIMINARY CHECK

The following visual checks should be made before troubleshooting an after installation or maintenance.

1.Check the power to the appliance and S8600.

2.Manual shutoff cocks in gas line to appliance must be open.

3.Make certain all wiring connections are clean and tight.

4.S86G, H module must not be in safety lockout. First de-energize the system and wait at least one(1) minute. This resets the module, allowing a return to start condition.

5.Review the S8600 system normal sequence of operation.

SYSTEM TROUBLESHOOTING

Start the system by setting the thermostat or controller above required temperature. Observe system response. Establish type of malfunction or deviation from normal operation. Use the S8600 Intermittent Pilot System Troubleshooting Table (Page 13) to check for normal system operation.

Use table by following instruction question in box. If the condition is true or okay (answers yes), go down to next box underneath. If the condition is not true or not okay (answers no), go right to the next box alongside. Continue checking and answering conditions in each box encountered, until a problem and/or the repair are explained. After any maintenance or repair, the troubleshooting sequence should be repeated until the troubleshooting procedure ends with normal system operation.
