What minimum amount of slope per foot should a vent connector have upward toward the chimney?

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

Answer: (B)

The minimum required slope for a vent connector that leads towards the chimney is 1/4 inch per foot. This specific slope is crucial because it helps ensure that any condensation that may occur within the venting system can effectively drain back toward the appliance, rather than pooling or collecting within the vent. If the slope is not sufficient, it could lead to improper venting, increased risk of blockages, and potential backdraft issues where exhaust gases could flow back into the living space instead of venting outside. Adhering to this requirement is vital for maintaining a safe and efficient venting system in gas appliances.
