The function of a combustion analyzer during an audit is to assess the efficiency of combustion appliances. This tool measures exhaust gases and combustion byproducts, providing real-time data on the performance of heating systems. By analyzing factors such as carbon monoxide levels, oxygen levels, and flue gas temperature, the combustion analyzer helps to determine how effectively an appliance is converting fuel into heat and whether it is operating within safe and efficient parameters. This information is crucial for ensuring that the appliance is not only energy-efficient but also safe to operate, reducing the risk of hazardous conditions like backdrafting or incomplete combustion.

In contrast, measuring indoor air quality pertains to evaluating contaminants in the indoor environment, while structural integrity assessments focus on the physical condition and safety of the building structure. Examining insulation effectiveness deals with how well insulation material is performing in terms of thermal resistance, which is separate from the specific function of a combustion analyzer. Thus, the focus of the combustion analyzer is clearly centered on evaluating combustion appliances and their respective efficiencies.
