The minimum required clearance for an unlisted pool heater on all sides and the rear is set at 12 inches. This requirement is established to ensure safety and proper operation of the heater. Adequate clearance allows for sufficient airflow around the unit, which is critical for preventing overheating and ensuring effective combustion for gas-fired heaters.

Maintaining this clearance also helps to facilitate maintenance and service access, reducing the risk of accidents and ensuring that any required repairs or inspections can be conducted safely. Furthermore, the increased distance from combustible materials minimizes fire hazards, which is particularly important for equipment placed near pool areas where moisture and potential obstructions can increase risks. Therefore, adhering to the 12-inch clearance standard helps to uphold both safety regulations and effective operational performance of pool heaters.
