Maintaining the required floor size of a fire chamber is essential to avoid combustion inefficiencies. If the floor size is not within the specified limits, it can lead to improper combustion of the fuel, which may result in incomplete burning. This inefficiency can cause increased emissions of harmful substances, wasted fuel, and reduced heat output. An adequately sized fire chamber ensures that the combustion process functions optimally, allowing for more complete fuel usage and maximizing heating effectiveness.

In addition to combustion efficiency, the other factors mentioned, such as insulation, airflow, and safety regulations, play a role in overall system performance and safety. However, the direct link between the floor size and efficiency of combustion is the most critical reason for adhering to the required dimensions of the fire chamber.
