Pellet stoves smokes and blows out in high winds

[Randy]

My sister in law bought a new pellet stove and when the wind blows directly on the outside wall the stove is vented outside on it blows the stove out and smokes out the house. What can she do about this? I suggested she direct the vent pipe up through the roof on the outside so am I right? I would appreciate any help on this asap please. Thanks!!

Can try and extend the exhaust pipe away from the side of the house getting it away from the preasure of the wind on the side of the house.

What happens then if the wind blows in that direction?

Think of the side of the house is just like a sail, the greatest preasure is closest to the surface and is negligible away from it. I have had to extend two vents a bit more than three feet each to eliminate wind issues here in the valley.

Ok thanks now I get ya. Would it be best to vent through the roof though?

Some other things to consider.
Putting to much venting outside if your temps are real low can freeze and plug.
Ease of cleaning, pellet stoves and thier venting need regular cleaning and climbing ladders in winter is hazardous.

You could go thru the roof, but you can also go around the eave, with a 45 degree elbow up and then another 45 degree elbow, to go up a minimum of 2 ft above the roof line. As others have mentioned you could go further out from the wall, but I think going above the roof line is the safest bet, but going out further from the wall may be an inexpensive solution to try first.

What type of vent termination is currently on the vent? Sometimes you can get by with just changing the termination to a hood style. Just something to think about.

Install an OAK. My stove wall faces the prevailing winds, which are quite strong very often. No problems with fire or smoke. My stove has a direct vent out through the wall, no rise.

An OAK will alleviate the pressure difference between the outside and the inside of the house. That pressure difference is your problem.
