What size chimney is needed for a factory with a total BTU input of 962,000 from two Category I fan-assisted appliances?

• A. 6 inch
• B. 8 inch
• C. 9 inch
• D. 10 inch

Answer: (C)

To determine the appropriate chimney size for a factory with a total BTU input of 962,000 from two Category I fan-assisted appliances, one must consider several factors, including the type of appliances, their configuration, and the manufacturer's specifications for venting requirements. Category I appliances typically require a chimney or venting system designed to handle a specific volume of flue gases, which relates directly to their BTU output. For fan-assisted appliances, the flue gas temperature and the volume and type of fuel being used also play a significant role in selecting the correct chimney diameter. In this scenario, the total output of 962,000 BTU needs sufficient venting capacity to ensure safe and effective exhaust of combustion gases. The general guideline for sizing vents for Category I appliances relies on the BTU output and the specific standards set forth in codes such as the National Fuel Gas Code (NFPA 54) or the International Fuel Gas Code (IFGC). Based on these considerations, a 9-inch chimney size is often considered the minimum required for high BTU inputs approaching 1,000,000 BTUs in such scenarios to maintain proper ventilation and prevent backdrafting issues. Therefore, the selection of a 9-inch chimney is essential for accommodating
