How should a vent connector be positioned with respect to the vent?

The proper positioning of a vent connector in relation to the vent is crucial for ensuring effective venting and preventing backdrafts or condensation issues. An upward slope is essential because it allows for proper drainage of condensation that may form within the venting system and promotes the flow of exhaust gases away from the appliance and out of the building. This configuration helps maintain a positive pressure within the vent system, which is important for the safe operation of gas-burning appliances.

If the vent connector were level or sloped downward, it could lead to a risk of gas buildup and potential hazards. A downward configuration may trap gases or moisture, impairing the overall functionality of the vent system. Therefore, having the vent connector positioned with an upward slope ensures that it facilitates optimal performance and safety in venting appliances.
