If your vent pipe is in good condition, you should be able to reuse it with your new water heater. Check your water heaters instruction manual for the correct vent pipe diameter. A reducer should NOT be used if the recommended vent pipe diameter is larger than the vent hood. Using adjustable vent pipe, insert one end into the water heater vent hood and begin attaching the other pipe sections. Be sure to check your water heater manufacturer manual for the correct diameter. Adjust the elbows prior to installing to allow the vent pipe to align as closely to straight as possible.

Secure all the vent pipe sections by pushing them together so that each fits tightly to the other. Use self-tapping sheet metal screws to secure the vent sections to the water heater vent hood and the other vent sections. Use at least 2 screws at each connection.

Open a hot water faucet, this will alert you that the tank is full. Check for leaks on each end of the two flexible water lines. When water runs from the hot water faucet, the tank is full. Allow the water to run for several minutes to eliminate the air in the tank.
