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.

    Appreciated your information and it greatly helped me in planning for our future pellet stove placement.

    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
    • Dominique Page
      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
    • Dominique Page
      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

      Hi am I able to take off vertical from the stove inside the house then exit horizontal a few feet above?

    How far should the cold air i take be from the exhaust of a pellet stove. Thanks,
    • Joe Bodden
      Roy, thanks for the question. It's always best to check with the manufacturers requirements regarding air intake distance from the exhaust cap on a pellet stove. If this info is not available, a good rule of thumb is 4 feet or more. I hope this answers your question, and thanks for your interest.

    I am installing a stove in my home using 80mm double walled tubes. The stove flue shoots out straight through the masonry wall into a Tee and then straight up. That is ok. The bottom end of the tee is supposed to have a removable cap for cleaning off pellet ash. My problem is that the removable cap is not on a ground floor but there is a 95 foot drop. I was wondering if I could extend the part where the ash cleaning cap is fitted by an additional 6 foot DOWN so that it can be reached out by a window on a lower floor in the building. There are no bends in the flue. All pipes are straight vertical. I do not know what effect such an addition to the pipework would do. Some advise would be welcome. Thanks
    • Joseph Bodden
      Tonio: Congratulations on your new pellet stove. We have a hunch you're really going to enjoy it! Extending the tee down for easier clean-out access should not pose a problem for you, as long as the same pellet vent pipe is used as the rest of the venting system and local codes permit a vent pipe to be installed that close to a window. But, as noted in the article, it's important that the joints of the pellet vent pipe are sealed. Most pellet vent pipe manufacturers have a gasket that seals the pipe when twist-locked together. If not, use silicone at each pipe connection. It's also important to thoroughly brace or support the pipe every 4 or 5 feet with a wall bracket support, so that the wind cannot move it and that it will remain secure when you remove the tee cap for cleaning. Thank you for your question and please spread the work about WeLoveFire.com to your family and friends!

    Can you use a brick chimney as the exhaust vent
    • Joseph Bodden
      Hello Art and thank you for your inquiry. You can use a brick chimney as a "conduit" to house a flexible, 4" stainless steel pipe, assuming that's the flue collar size of your pellet stove. It's important to size the vent pipe properly from the stove all the way to the cap. If you just run the correct size pellet vent pipe to the chimney, you're going to be asking for trouble because the existing brick chimney will be too large. The difficulty with a chimney to big for the appliance is that the by products of combustions will linger in the chimney too long because of insufficient draft. Deterioration of the inside of the brick chimney will soon follow. By installing the proper size vent for your pellet stove, you're ensured that the velocity of the draft will be sufficient to dispel the by-products to atmosphere. So, our recommendation is to run pellet vent pipe to the brick chimney, then with adapters use a flexible 4" stainless steel pipe up the brick chimney. Terminate the SS pipe at the top of the brick chimney with an anchor plate, support clamp and a cap with a storm collar. You'll be happy you did it the correct way and likely get better performance from your stove, too!

    I am replacing my old pellet stove and the location of the flue outlet is not the same . I am using a 45 and a 90 degree turn then a 12"section that goes through the wall thimble to a tee with a clean out. then it goes straight out through the eave. Is this to many bends?
    • Joseph Bodden
      Alan: Thank you for your question. If I'm picturing the venting profile correctly, you're coming off the back of the stove with a 45 degree elbow, followed by a 90 degree elbow and a 12" length of pipe through the wall to a tee. From this tee you said you're going straight OUT through the eave. Did you mean straight UP through the eave? If you meant UP through the eave, I think you should be in pretty good shape. As you read in the article, it's always a good idea to get some vertical rise with pellet vent pipe. Pellet stoves have a fan assisted exhaust system. Without any rise in the vent pipe there could be a potential issue with smoke backing up into the house if power is interrupted while the stove is operating. But with vertical rise either inside or outside the house, there will be a natural draft established if power is interrupted. This will help to remove the smoke from the stove if there's a power failure or if a little one accidentally unplugs the stove from the wall outlet. The key is getting some rise with the pipe, either inside or outside the house. Usually 3-4 feet (or more) of rise is adequate. That being said, I would encourage you to thoroughly read the owner's manual and definitely check with the dealer where you bought the pellet stove as there may be limits or restrictions on the venting profile. Good luck and thanks again for your inquiry Alan. Please tell your family members and friends about WELOVEFIRE.com!
