How to Install a Fresh Air Vent for a Pellet Stove in a Log Home

Obtain a fresh air vent kit if one did not come with your stove. You will need a steel pipe or noncombustible flex pipe with a steel interior. The piping must be compatible with the size of the intake valve on the back of the stove. In many cases, the intake valve is 3 inches in diameter, but measure yours to be sure. An elbow joint for the termination point and ring clamps are also required.

Set the stove in its intended location and complete the installation of the main venting system. Identify the intake valve on the back of the stove.

Cut a hole in the wall that lines up with the intake valve and matches its diameter. This may take several steps and the use of multiple tools. One way to achieve this is to firstly use a hole saw to grind as deep as you can into the surface. The hole saw may only allow you to cut 2 to 3 inches deep, but many log homes are 6 inches or more thick. Switch to a jig saw and continue cutting out the circumference of the circle as deep as possible. If necessary, switch back to the hole saw until you have cut completely through the wall.

Connect the pipe to the intake valve of your stove by sliding it in place or using ring clamps. When securing in place, adhere to manufacturer instructions, if they are available.

Run the piping through the wall until it reaches just past the exterior.

Install a down-turned, 90-degree elbow joint or a vent hood where the pipe terminates. Place a metal screen on the end of the pipe to keep out animals.
