What must be done if an appliance is installed in a confined space?

When an appliance is installed in a confined space, providing adequate ventilation is essential to ensure safe operation and compliance with the National Fuel Gas Code. Confined spaces can limit airflow, which may lead to insufficient oxygen for combustion. This can increase the risk of carbon monoxide buildup, potentially posing serious health hazards.

Adequate ventilation allows for the necessary airflow to support combustion processes and also helps to remove any combustion byproducts, maintaining a safe environment. Following the code's specifications for ventilation ensures that the appliance operates efficiently and safely, preventing negative effects on indoor air quality and adhering to safety standards. Therefore, it is crucial to assess the space and implement appropriate ventilation solutions as mandated by the applicable regulations.
