New York Low Pressure Boiler COF Practice 2026 - Free Practice Questions and Study Guide

Gas-fired boilers with a heating surface not exceeding 100 square feet must be equipped with a hood diverter that can be either of the single or double cone type. This flexibility allows for various designs that meet installation requirements while ensuring safe operation of the boiler.

A single cone diverter effectively directs flue gases, helping to ensure proper venting and preventing backdraft or the possibility of flue gas leakage into occupied spaces. On the other hand, a double cone diverter offers an additional layer of efficiency and safety, enhancing the dispersion of combustion gases before they exit the system.

This requirement is in place because the appropriate type of diverter significantly contributes to proper ventilation, ensuring that combustion gases are directed safely away from the area and minimizing the risk of hazardous buildup. Using either single or double cone diverters provides the necessary safety assurances while accommodating different boiler configurations.

Understanding this aspect is crucial for ensuring compliance with safety regulations and enhancing the overall functionality of gas-fired boilers in settings with limited heating surface areas.
