What is the appropriate action if a vent pipe is improperly pitched?

Adjusting the vent pipe to pitch toward the furnace is the correct action because proper venting is essential for safe and efficient operation of heating systems. If a vent pipe is improperly pitched, it can lead to condensation, which could cause water to accumulate in the pipe. This accumulation can create an environment conducive to corrosion and may obstruct the flow of exhaust gases. By ensuring that the vent pipe is pitched correctly, you support effective drainage of condensation back toward the furnace, thus improving the overall performance and safety of the heating system.

Proper pitch helps maintain the necessary airflow and pressure within the venting system, ensuring that harmful flue gases are expelled from the home safely. Proper installation and maintenance of vent pipes are critical to compliance with building codes and standards for safe heating system operation.
