What is the purpose of a combustion analyzer in a gas furnace?

The purpose of a combustion analyzer in a gas furnace is to assess the efficiency and safety of the combustion process. This instrument plays a crucial role in ensuring that the furnace is operating correctly and safely. It measures various parameters, such as the carbon monoxide levels, carbon dioxide levels, excess oxygen, and flue gas temperature. These measurements help technicians determine whether the combustion process is complete and whether the furnace is burning fuel efficiently.

Using a combustion analyzer allows for the adjustment of air-to-fuel ratios, ensuring optimal performance and minimal emissions. This is vital not only for the efficiency of the system but also for the safety of the occupants, as improper combustion can lead to dangerous conditions like carbon monoxide poisoning. Therefore, the overall goal of the combustion analyzer is to ensure that the heating system operates at peak performance while maintaining safety and compliance with environmental standards.
