How should vent connectors be installed to prevent dips or sags?

To ensure the proper function of vent connectors and prevent the accumulation of condensate, they should be installed with a constant upward slope. This method facilitates the efficient movement of flue gases away from appliances and into the venting system. An upward slope encourages any condensation that may form to flow back toward the appliance rather than pooling in the connector, which could potentially lead to blockages and inefficiencies.

When vent connectors are installed correctly with this upward incline, it enhances the overall performance and safety of the venting system. This approach is fundamental in maintaining adequate draft and minimizing the risk of venting failures, as properly directed condensate reduces the potential for corrosion and related issues impacting the longevity and operation of the vent system.

Other installation angles, such as horizontal or downward slopes, can create areas where condensation can accumulate, which is contrary to the intended design of an effective venting system.
