Proper operation relies on correct wiring, as illustrated in Fig․ 1, and accurate adjustment of control settings․
Gas Ignition Process Overview
The Honeywell S8610U initiates the gas ignition process through a carefully orchestrated sequence․ Initially, the control energizes the gas valve, allowing a small volume of gas to flow to the pilot burner․ Simultaneously, it activates the igniter, creating a spark to ignite the gas-air mixture․ Form 69-1955 comprehensively details this process, including timing parameters and safety checks․
Flame rectification, a key safety feature, verifies successful pilot ignition․ Once a stable pilot flame is detected, the control proceeds to open the main gas valve, initiating burner operation․ Fig․ 1 illustrates the typical wiring connections for this system․ Any interruption in this sequence triggers a lockout, preventing gas flow and ensuring safety․
Understanding this process is vital for diagnosing ignition issues and performing effective maintenance․

Troubleshooting Common Issues
Refer to Form 69-1955 for diagnosing ignition failures, flame rollout problems, and lockout situations with the S8610U, ensuring safe operation․
Diagnosing Ignition Failures
Ignition failures with the Honeywell S8610U often stem from several key areas, requiring a systematic approach to diagnosis․ First, verify the gas supply is active and reaching the appliance; insufficient gas pressure is a common culprit․ Second, inspect the igniter itself for visible damage or lack of glow – a faulty igniter necessitates replacement․
Third, carefully examine all wiring connections, as loose or corroded wires can interrupt the ignition sequence․ Referencing Fig․ 1 in the manual (Form 69-1955) is crucial for correct wiring verification․ Fourth, check the flame sensor; a dirty or misaligned sensor won’t detect the flame, causing a lockout․
Finally, consider the control module itself; intermittent failures may indicate an internal issue requiring professional assessment or replacement․ Always prioritize safety and disconnect power before inspecting any electrical components․ Detailed troubleshooting steps are outlined within the comprehensive S8610U manual․
Addressing Flame Rollout Problems
Flame rollout, a serious safety concern with the Honeywell S8610U, indicates the flame is lifting from the burner and contacting the appliance’s exterior․ First, ensure proper gas pressure – too low or too high a pressure can cause unstable combustion․ Second, inspect the burner for obstructions like dust or debris, hindering proper flame pattern․
Third, verify correct burner alignment; misalignment can lead to flame impingement and rollout․ Fourth, check the venting system for blockages, restricting airflow and causing flame instability․ Referencing Form 69-1955, the full S8610U manual, provides detailed venting specifications․
Fifth, a faulty flame sensor can falsely indicate flame presence, allowing gas flow without proper ignition, leading to rollout․ Immediately shut off the gas supply and address the issue before attempting restart․ Consult a qualified technician if the problem persists, as flame rollout poses a significant fire hazard․
Resolving Lockout Situations
Lockout on the Honeywell S8610U signifies the control has repeatedly attempted ignition without success, shutting down the gas supply as a safety measure․ First, verify the gas supply is on and adequate pressure is reaching the control․ Second, check for a blocked vent pipe, restricting proper combustion airflow․
Third, inspect the flame sensor for cleanliness and proper positioning; a dirty or misaligned sensor won’t reliably detect the flame․ Fourth, review the wiring connections, ensuring secure and correct connections as detailed in Fig․ 1 of the S8610U manual (Form 69-1955)․
Fifth, a faulty gas valve can prevent gas flow, triggering lockout․ To reset, typically a manual reset button is located on the control module․ However, repeated lockouts indicate an underlying issue requiring professional diagnosis and repair․ Ignoring lockouts can lead to dangerous gas buildup․
