FILTER CAUTION: This furnace requires unrestricted airflow for combustion and ventilation. For proper and safe operation, it is extremely important that the furnace receives an unobstructed flow of clean, fresh air to properly burn the fuel gas. If this flow of air is restricted, the partially burned combustion gases may create dangerous amounts of carbon monoxide that can cause personal injury or death.
