• A. 8 feet
• B. 10 feet
• C. 12 feet
• D. 15 feet

Answer: (C)

For a Type B-W gas vent, the requirement stipulates that the minimum vertical height must be at least 12 feet above the bottom of the furnace. This specification is crucial for ensuring that the vent operates effectively by providing sufficient draft for exhaust gases to rise and disperse safely. A proper height minimizes the chances of backdraft and promotes the effective expulsion of combustion byproducts, which is vital for safety and efficiency in gas appliances. Ensuring that the vent meets this height requirement is essential in preventing issues related to venting efficiency and potential health hazards from the improper release of gases. This regulation is in line with industry standards to maintain safe and effective operations of gas appliances.
