For a Category I appliance, what is the required slope for a vent connector toward the chimney or vent?

• A. 1/8 inch per foot
• B. 1/4 inch per foot
• C. 1/2 inch per foot
• D. 3/4 inch per foot

Answer: (B)

The required slope for a vent connector toward the chimney or vent for a Category I appliance is 1/4 inch per foot. This slope is essential to ensure that any condensate that may form within the vent connector properly drains back toward the appliance instead of pooling in the vent. Proper drainage helps maintain the efficiency of the venting system and prevents potential issues such as vent blockage or corrosion. A slope of 1/4 inch per foot is considered an industry standard that balances efficient venting and adequate drainage, ensuring the safe operation of gas appliances. Other slopes such as 1/8 inch, 1/2 inch, or 3/4 inch per foot could lead to insufficient drainage or excessive pitch, which could result in operational issues and safety risks.
