    Default How to vent Grill Smoke

    Hi everyone. I have a patio, roughly 15'x25' that has a ridged roof with a passive ridge roof vent installed (there is no finished ceiling). I framed out and installed a system that allows the patio to be screened during the summer months, but it also has soft plastic panels which travel on a track which allows the patio to be enclosed during the cold months/bad weather. I have two ceiling fans installed in the space. Heres my dilemma/question. I like to barbecue out here all year long. When the patio is "open" (screened), it hasn't been too much of a problem with smoke buildup due to pretty good air circulation/fans. During the winter, I usually try to open some of the panels AND put the ceiling fans on...but the area turns into a smokehouse with the fans just swirling around the smoke. What can I do? Are there any types of grills/barbecue kits that I can place in the space that would vent the smoke out (of a chimney)? Is there anything I can do up in the ridge to possibly help exhaust the smoke out of the ridge vent? Exhaust fans in the roof? I like being able to barbecue when it's raining or snowing outside SO I'd rather not locate the grill outside of the space. Thanks for any input.

    I think I would install something along the lines of a attic fan/gable vent or better would probably be a power vent (whirlybird).

    Here's the thing, with the smoke rising and getting trapped in the roof structure, you've got to get an exhaust fan up there to remove it. A side venting gable vent would probably be the best/easiest, however the smoke is going to discolor the outside wall and eaves.

    If you go with a power vent through the roof you won't have that problem. I believe that you can either purchase an eyebrow vent with a fan or you can get a whirlybird with a fan.

    I think gable fans might be the easiest solution. I would probably put a fan in each gable and maybe switch them separately so depending on the wind direction you might only need one turned on.

    I also could see an upblast exhaust fan, the kind that are seen on restaurants as being a good solution. I only have seen them in commercial installations, so they may not be easy to get and be somewhat expensive. The fan could be located over the grill to take the smoke out more directly.

    How about a conventional type kitchen range hood mounted relatively close to the grill, but not too close so as to avoid flame ups. Try to intercept the smoke before it goes all over the enclosure.

    I was thinking the same thing too like a free standing island type of fan hood. Somebody probably makes one rated for an outdoor installation.
    I like to grill all winter too, except mine is on an open deck. Snow, rain & wind puts a damper on it. The cold weather works in my favor though when grilling things like birds or roasts that take hours to cook.

    Personally, I doubt you can get enough air flow from the typical residential range hood to make much of a difference, unless it was directly over the exhaust of the grill, even then it would be over burdened. A bath fan would move more air, but I still think the OP needs something to clear the cathedral ceiling area.

    You could be right Spruce. I haven't researched it that much. The cheaper units probably would not. They tend to be noisy too.

    I have bought venting devices from this website before: www.ventingdirect.com
