90 seconds

The pre-purge time for a low pressure boiler is typically set to 90 seconds. This duration is essential for ensuring that any residual combustion gases are cleared from the combustion chamber before the ignition sequence begins. A proper pre-purge helps to prevent the risk of explosion from igniting accumulated gases, thereby enhancing safety during operation.

This time frame allows for sufficient ventilation, ensuring that any potentially harmful gases are expelled, which is critical in a safety-conscious environment such as that governed by New York's low-pressure boiler operations. By adhering to this standard, operators can ensure safer startup procedures while maintaining compliance with safety regulations. Understanding the role of the pre-purge cycle is crucial for anyone involved in the operation and maintenance of low pressure boilers.
