How do I properly vent my pellet stove?

You probably will have a few options for venting a pellet stove. Most pellet stoves require type “L” vent pipe. Many will have a 4” vent pipe requirement. L-vent uses a small air space between a stainless steel inner pipe and a galvanized outer pipe. Since the exhaust on pellet equipment is pressurized, all joints between pipe components must be siliconed or have a tight, gasketed/sealed connection.

Pellet stoves can be vented vertically through the roof or horizontally through a side wall. It’s always a good idea to get some vertical rise with the L-vent pipe, before venting horizontally through a side wall. If power is interrupted while the stove is operating, there will be a natural draft established with a bit of rise in the vent profile. This will help to remove the smoke from the stove if there’s a power failure or little hands accidentally unplug the stove from the wall outlet. This vertical rise can be achieved inside before the vent pipe is exited through the sidewall, or outside if you prefer an installation with no pipe showing inside. Inside or out, usually 3 or 4 feet of rise is sufficient.

If you plan to replace a wood burning stove with a pellet model, another venting option is to use the existing chimney for the wood stove. Rigid L-vent pipe can be installed from the pellet stove to the chimney. Special adapters at the chimney will allow a 4” flexible, stainless steel pipe to be installed up the chimney. Your dealer can help you evaluate your best venting option.

Never use PVC pipe, gas vent pipe, dryer vent pipe or single wall black stove pipe to vent your pellet stove.

    I purchased a Wise Way gravity feed pellet stove and would like to put it in my basement. What horizontal venting system would you recommend?? Thanks

      Hello Richard, thanks for reaching out. I am not familiar with the Wise way pellet stove. It might be best to contact the store where you bought it from, or reach out to the manufacturer for guidance. Stay warm! Dominique

    Hi, if I run the vertical rise on the exterior of the house, how much clearance do I need from the ground where the elbow/T for the vertical rise begins? I know the top of the exhaust pipe needs to be a minimum of 3' but is there a ground clearance for the base of the rise? Also, if the exhaust runs through a brick wall, can I just run the pipe out without the 3" wall thimble? Thanks, B

      Hello Bonnie Thanks for reaching out. You need to keep at least one inch to combustibles with pellet vent. As per the wall thimble, it is mandatory to use it. All the best! Dominique
