What is the proper flame current range for a Honeywell spark ignition module?

The proper flame current range for a Honeywell spark ignition module is commonly recognized to be between 1 to 1.5 microamps. This range is critical for ensuring that the ignition module effectively detects the presence of a flame. The flame current is generated by the ionization of the combustion products and is an essential factor that the module uses to confirm that combustion is taking place safely and effectively.

In this context, if the flame current falls below 1 microamp, it may indicate a weak or nonexistent flame, prompting safety protocols to prevent gas leaks or other hazardous situations. Conversely, a current exceeding 1.5 microamps could suggest an overly rich mixture or other issues that might compromise system performance or safety. Thus, operating within the specified range ensures reliable ignition while maintaining safe operational conditions for the equipment.
